windows 10 hack ,ways to stop update

There is no greater Windows 10 controversy than its policy of forced updates. While great in theory, for many users the reality of updates which download and install automatically has been horribly differentand the question on many users lips is: How do you stop them?

Now we have an answer: with three potential options. Each has its own pros and cons, so read on to find out which is most suitable for you.

Word of Warning: automatic updates are typically a good thing and I recommend leaving them on in general. As such these methods should primarily be used for preventing a troublesome update from automatically reinstalling (the dreaded crash loop) or stopping a potentially troublesome update from installing in the first place.

Limitations - For Windows 10 Home users there is no way to stop security updates. These are not delivered using the Windows Update Service, but I would not recommend stopping them in any case. The methods below are to give you power over feature and driver updates, less essential areas where I believe users should have control.

Windows 10 will be great, but it needs more time - Image credit Microsoft

Option 1: Stop The Windows Update Service

As central as it is to the core of Windows 10, Windows Update is actually just another Windows process so it can be stopped with these simple steps:

1. Open the Run command (Win + R), in it type: services.msc and press enter
2. From the Services list which appears find the Windows Update service and open it
3. In ‘Startup Type’ (under the ‘General’ tab) change it to ‘Disabled’
4. Restart

To re-enable Windows Update simply repeat these four steps, but change the Startup Type to ‘Automatic’

Option 2: Setup A Metered Connection

Windows 10 offers users on metered connections a compromise: to save bandwidth Microsoft confirms the operating system will only automatically download and install updates it classifies as ‘Priority’.

While Microsoft doesn’t reveal its method of classification, this does cut down more frivolous updates which typically include new drivers and software features - both of which have already caused stability problems.

1. Open the Settings app (Win + I)
2. Open the ‘Network & Internet’ section
3. Open ‘Wi-Fi’ and click ‘Advanced Options’
4. Toggle ‘Set as metered connection’ to ‘On’

Note: If your PC uses an Ethernet cable to connect to the Internet the Metered Connection option will be disabled as it works with Wi-Fi connections only (silly I know).

Windows 10 is the single operating system working across all Microsoft desktops, laptops, tablets and phones

Option 3: Group Policy Editor

This is a halfway house: the group policy editor will notify you about new updates without automatically installing them (how previous generations of Windows always worked) - though again security updates will still install automatically.

Note: Windows 10 Home users have to sit this one out, it is only for Windows 10 Education, Pro and Enterprise editions.

1. Open the Run command (Win + R), in it type: gpedit.msc and press enter
2. Navigate to: Computer Configuration -> Administrative Templates -> Windows Components -> Windows Update
3. Open this and change the Configure Automatic Updates setting to ‘2 - Notify for download and notify for install’
4. Open the Settings app (Win + I) and navigate to -> Update and Security -> Windows Updates. Click ‘Check for updates’ which applies the new configuration setting
5. Restart

Read more - Windows 10: Should You Upgrade?

Alternatively for Windows 10 users without group policy access:

1. Open the Run command (Win + R), in it type: regedit and press enter
2. Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU
3. In there create a ‘32-bit DWORD’ value called ‘AuOptions’ and under ‘Value Data’ type 2 and click ‘OK’
4. Open the Settings app (Win + I) and navigate to -> Update and Security -> Windows Updates. Click ‘Check for updates’ which applies the new configuration setting
5. Restart

Antivirus safe your mobile

Your phone probably has sensitive information on it, so it may be a good idea to install some security software on it. There’s some debate about whether you really need antivirus apps on your smartphone. Much depends on whether you sideload apps, but there’s no denying that malware has grown into a much greater concern since we first wrote this article back in 2012. Luckily, security apps have improved dramatically to keep pace with the new threats, so you have plenty of great protection to choose from.

The majority of security apps go beyond antivirus protection for Android to include a host of other tools from contact filtering to remote lock or wipe. We decided to take a look at the top five Android security apps and find out what they do. We are taking a look at these from a consumer point of view, so be warned that some of the "free" apps are only free for personal, non-commercial useAveraging a 99.9 percent malware detection rate over the last two years, Trend Micro is a consistently solid choice. In the latest report, it managed 100 percent for real-time detection and 100 percent for malware discovered in the last four weeks. It also returned no false positives and it won’t impact noticeably on battery life or performance.

You get a handful of other tools with the free version of Trend Micro’s app. There’s protection against phishing sites, a privacy scanner for Facebook, and some tools to help you save battery life and memory. There’s also a neat “Just-a-Phone” feature that kills all non-essential background processes. There’s a 7-day free trial of the premium features, which include malware blocking and cleaning, anti-theft tools, app locking, call filtering, and more. At $36 per year, we’re not convinced it’s worth it, but the free version will cover you for malware detection and it already has some handy extras.As a genuinely free app for the Android platform, Avast Mobile Security offers an impressive range of tools. It has antivirus protection, it scans your apps to provide details on what they are doing, and it has a web shield that scans URLs for malware.

There are various additional tools in the package including a call blocker for blacklisting problem numbers, an app locker to PIN protect private apps, and Wi-Fi scanning options for improved security and speed. Sadly, the app locking and anti-theft features require you to subscribe to the "Pro" version, which also removes ads and gives you direct support access from the app.

If you have a rooted device, then there’s also a firewall that allows you to control network traffic. You can block access to Wi-Fi or the network for specific apps, which is handy for security and may potentially save battery life as well.According to the latest AV-Test report of 21 popular Android security apps from September 2017, Avast is a solid option with a detection rate of the latest Android malware in real time of 99.8 percent, rising to 100 percent for malware discovered in the last four weeks. That puts it near the very top of the charts in terms of malware detection, which, combined with the extra functionality, makes it worth considering. It has a light footprint with no discernible drain on battery life and no impact on general performance. It also returned no false positives.

The free version of this Android security app provides a decent range of features, keeps you safe from malware, and offers extra protection for rooted devices, making it a strong contender. If you’re looking for a security solution for your Android smartphone, and your primary concern is malware and safe browsing, then this could be the right app for 

IDM CRACK MANUALLY FOR WIN 7

CRACK IDM MANUALLY (SPECIALLY FOR WINDOWS 7 USERS)

Hi Friends,

Mostly time after updating your IDM, it shows error "you have registered IDM using fake serial key". In my old post, I posted to download IDM without any keygen, but it shows error while installing it in Windows 7 something like "Windows cannot find 'crys18.exe' make sure that u typed the name correctly". Later I search on net how to crack IDM, then finally I found a solution. If you are windows 7 users, then this post is for you, because for XP/Vista users , users can easily access full version IDM by downloading it from here without any keygen & error, follow these steps:

• Download the IDM, then click on Registration.

Safe using of social media

With so many of us using social media today, sites like Facebook, Twitter, and LinkedIn make perfect targets for scams.

Here are our top 10 tips to stay safe on social media:

1. Use a strong password.  The longer it is, the more secure it will be.
2. Use a different password for each of your social media accounts.
3. Set up your security answers.  This two factor authentication is available for most social media sites.
4. If you have social media apps on your phone, be sure to password protect your device.
5. Be selective with friend requests. If you don’t know the person, don’t accept their request.  It could be a fake account.
6. Click links with caution.  Social media accounts are regularly hacked.  Look out for language or content that does not sound like something your friend would post.
7. Be careful about what you share. Don’t reveal sensitive personal information ie: home address, financial information, phone number.  The more you post the easier it is to have your identity stolen.
8. Become familiar with the privacy policies of the social media channels you use and customize your privacy settings to control who sees what.
9. Protect your computer by installing antivirus software to safeguard.  Also ensure that your browser, operating system, and software are kept up to date.
10. Remember to log off when you’re done

Safe using of emails

Email is a wonderful tool for sending and receiving a lot of information quickly and securely. However, it’s important that your personal information remains secure and safe and that you aren’t open to viruses or hackers.

 

Here are some safety tips when using email:

 

• Change your password regularly and keep it in a safe place.
• Don’t share your password with anyone.
• Don’t open attachments from anyone you don’t know.
• Log out or sign off from your account when you’ve finished looking at/sending your email.
• Don’t reply to spam or forward chain emails.
• Keep your personal information personal – don’t share bank or credit card information by email.
• Your bank will not discuss your private financial situation by email. If you receive any correspondence that claims to come from your bank, telephone your branch to verify it and discuss the matter over the telephone instead.
• Make sure that you have antivirus software installed and keep it up to date.

 

Trouble shooting of motherhood

Troubleshooting a Computer Motherboard

The motherboard is the computer, so the usual symptom of a failed motherboard is a completely dead system. Fans, drives, and other peripherals may spin up if the motherboard is dead, but more often nothing at all happens when you turn on the power. No beeps, no lights, no fans, nothing.

If you think you have a dead motherboard, think again. The most likely cause of a dead system is a blown fuse or breaker at the wall receptacle. If you're certain the system is getting power and you have just installed the motherboard, it's much more likely that you've neglected to connect a cable or made some other basic error than that the motherboard itself is bad, assuming of course that the problem motherboard is a highquality product.

When Bad Motherboards Turn Good

Many online vendors have stopped accepting returns of "bad" motherboards for just this reason. As it turns out, about 19 of 20 motherboards returned as defective are perfectly good. The buyer simply didn't install the motherboard correctly. Even so, many upgraders choose to buy their motherboards from a big-box store or other local source, because of their generally better return policies. In fact, some people troubleshoot their systems by buying a motherboard locally and then returning it if the motherboard turns out not to be the problem. We think that's unethical, but as any vendor will tell you, it's common practice.

What's in a Name?

Most name-brand motherboards, particularly those made by Intel and ASUS, are of very high quality; cheap motherboards, including those used in most consumer-grade mass-market systems, are of very poor quality. We've used Intel and ASUS motherboards for years. In a shipment of 100 motherboards, it's unusual to find even 1 DOA. In a shipment of 100 cheap motherboards, it's not uncommon to find half or more DOA, and many of the remainder failing soon after they're installed.

In a working system, it's very uncommon for a high-quality motherboard to fail other than from lightning damage (see Computer Power Supplies and Protection) or other severe abuse. In particular, it's nearly unheard of for a motherboard to fail while it is running, as opposed to when you start the system. A dead system is more often caused by a dead power supply than a dead motherboard, so the first step to troubleshoot an apparently dead motherboard is to swap in a known-good power supply. If the system remains completely dead with a known-good power supply, it's likely that the motherboard is defective and must be replaced.

It's not uncommon for a motherboard to fail partially. For example, an ATA interface or the embedded video, audio, or LAN may stop working, while the rest of the motherboard functions appear to work normally. It's possible to work around such partial failures; for example, by disabling the failed function in BIOS Setup and installing an expansion card to replace the failed embedded function. We recommend against this practice, however, because a partial motherboard failure is often soon followed by a complete failure.

Configuring CMOS

Each time a system boots, the BIOS boot screen appears momentarily. While this screen is being displayed, pressing a designated key runs the CMOS Setup program, which resides in firmware. CMOS Setup is used to configure BIOS and chipset settings ranging from those as obvious as the Date and Time to those as obscure as memory timings and bus settings.

BEAUTY IS ONLY SKIN DEEP

Some motherboards replace the standard BIOS boot screen with a logo splash screen. Display the standard BIOS boot screen on such systems by pressing the Escape key while the logo is visible.

To invoke CMOS Setup, you normally press F1 (AMI), Del (Award), or F2 (Phoenix). Other BIOS manufacturers use different keys, and some system and motherboard manufacturers modify a standard BIOS to use another key. The key that invokes CMOS Setup nearly always appears on the BIOS boot screen, but if your BIOS boot screen isn't displayed or doesn't show that key, try Esc, Del, F1, F2, F10, Ctrl-Alt-S, or refer to the documentation.

The exact appearance of CMOS Setup and the available options depend on the chipset, the BIOS make and version, and changes made to the BIOS and CMOS Setup programs by manufacturers. For example, two motherboards may use the same chipset and BIOS, but one may give users complete freedom to configure chipset options, and the other allows users access to only some of the settings and uses hard-wired values for other settings.

All BIOSs default to a reasonable set of settings, one that allows the system to boot and function normally. Beyond that, it's up to you to choose settings to configure the system as you want it and to optimize its performance. Some BIOS settings are obvious things like time and date, power management, boot sequence, and so on. Others, particularly those segregated as advanced settings and chipset settings, are anything but obvious. The brief help descriptions provided with them are usually not much help unless you already understand the issue. The primary rule here is if you don't understand what a setting is for, don't change it.

That's easy to say, but it ignores the fact that accepting default settings for obscure options can result in a PC that performs significantly below its potential. PC and motherboard manufacturers differ in how "aggressive" they are in choosing default settings, particularly those for such things as memory timing. Those that tend toward slower, more conservative default settings say, with some justification, that they cannot predict what components particularly what speed and quality of memory a user will install. Choosing conservative settings allows them to be sure that the motherboard will at least work, if not optimally. Those who are more aggressive often PC makers who control the specific memory and other components that are installed and who assume that users want the highest possible performance level and use components that support those aggressive settings.

The first place to look for detailed CMOS Setup instructions is in the manual that came with the computer or motherboard, or on the web page that supports that product. Some manufacturers provide detailed explanations of general CMOS Setup and Chipset Setup options, but many cover only basic BIOS settings and ignore chipset settings entirely. If that's the case with your manual, the best sources of information about advanced BIOS settings are Wim's BIOS (http://www.wimsbios.com) and Phil Croucher's The BIOS Companion(http://www.electrocution.com/biosc.htm).

Updating the BIOS

When you upgrade a system without replacing the motherboard, the BIOS version it uses can be a critical consideration. Some system features e.g., support for faster or more recent processors, large hard disks, high-speed transfer modes, and AGP are BIOS-dependent, so an in-place upgrade often requires a BIOS upgrade as well. Fortunately, recent systems use a flash BIOS, which can be upgraded simply by downloading a later version of the BIOS to replace the existing BIOS.

Don't Take Chances

Be extraordinarily careful when upgrading the system BIOS. Make absolutely sure that the BIOS upgrade patch you apply is the exact one required for the current BIOS. Applying the wrong BIOS update may make the motherboard unusable, short of returning it to the factory for repair.

The exact method required to update the BIOS varies by motherboard manufacturer and model. Some motherboards are updated simply by copying the updated BIOS file to a floppy disk or CD and booting from it. Other motherboards use a DOS-based "flasher" program that runs from floppy disk and installs the BIOS file when it executes. Intel motherboards support Intel Express BIOS Update, which allows updating the BIOS from within Windows simply by double-clicking an executable file. (Fortunately, Intel also provides floppy disk based BIOS update routines that those of us who run Linux or other non-Windows operating systems can use to update our BIOSs.)

Although updating the BIOS is a pretty intimidating operation the first time you try it or the tenth time, for that matter BIOS updates usually complete successfully if you do everything by the numbers. But if you accidentally apply the wrong patch or if the update process fails through no error of your own, the PC can end up nonbootable. If this happens, there may not be an easy way to recover. Depending on the BIOS, one of the following methods to recover from a failed BIOS update may be usable:

• A few motherboards have dual BIOS chips. If you corrupt one BIOS during an update, you can boot the system from the other BIOS and reflash the corrupted BIOS.
• Intel motherboards have a jumper that configures the motherboard for one of three modes of operation: Normal, BIOS Update, and Recovery. To update the BIOS, you must set that jumper to update mode. If the update fails for any reason, you can reset the jumper to the Recovery position, which gives the motherboard just enough smarts to access the floppy drive at boot time and attempt to load a BIOS update from the floppy drive.

BELT AND SUSPENDERS

Because a failed BIOS update can have such dire results, never update a BIOS without first connecting the system to a UPS, if only temporarily while doing the update. The one time we violated that rule, sure enough, the lights flickered about five seconds after we started the update. Hoping against hope that the PC hadn't crashed (this update was one where the screen stays blank until the update is complete), we sat staring at the blank screen for another half hour before we admitted to ourselves that we'd probably just killed the motherboard. With our fingers crossed, we powered the system down and back up again, but, as expected, it was deader than King Tut. Unless your luck is better than ours, always use a UPS when flashing a BIOS.
