Windows 11 release date is closing in, some people have tried it via insider build, some have decided not to. It has come to our attention that there is a little website made by BlueEdge that offers a virtual Windows 11 desktop. Opening the Website will put you right inside Windows 11 desktop, now take note that this is not Windows 11, it is a simulation of Microsoft’s newest OS and therefore many things will not work like File Explorer, etc. One thing you can make sure it is working is UI itself, you can see how you do like the new Taskbar, start menu, widgets, and some other things. You can just pop up on the site and check how you do like the overall new look and feel of Windows 11 UI before installing it or trying it. We are sure that many more options will come in time but even now you can get a feel of the newest OS. Windows 11 BlueEdge site: https://win11.blueedge.me/

As of late, users have been reporting about getting an error saying, SAFE_OS phase error during Replicate_OC operation when they tried to upgrade their Windows 7 or Windows 8.1 computers to Windows 10. Although the error code in this problem could vary, in this situation, it states:

0xC1900101 – 0x20017, The installation failed in the SAFE_OS phase error during Replicate_OC operation

To fix this issue, you need to follow the given options below. But before you do, you need to create a System Restore point first so that if anything goes wrong, you can always undo the changes you’ve made.

Option 1 – Try to change the Windows 10 installation

According to security experts, one of the main causes of this error is the KB3064209Windows Update. This particular update is the one responsible for updating the CPU Microcode for processors made by Intel. Thus, if you don’t use an Intel processor, you can skip this option and proceed to the next one. However, if you use Intel, make sure to follow the instructions in this option carefully. Take note that in this solution, C: partition is referred to as the OS Partition while H: partition is referred to as the USB Pen Drive.

• First, you need to download the Windows 10 ISO from the Windows 10 Media Creation tool and then copy its contents to the Pen Drive H.
• Next, tap the Win + X keys and click on the Command Prompt (Admin0 option. If a User Account Control appears, simply click Yes.
• After opening Command Prompt, type the following command:

dism /Mount-Image /ImageFile:H:sourcesboot.wim /index:1 /MountDir:C:UsersUserDesktopmount

• Now navigate to the following path in the Windows File Explorer:

C:UsersUserDesktopmountWindowsSystem32mcupdate_GenuineIntel.dll

• From there, right-click on the file named “mcupdate_GenuineIntel.dll and click on Properties.
• Next, go to the Security tab and click on Advanced. In the Advanced section, change the Owner to your User Account and click OK.
• And then back to the Security tab, click on the Edit button and check on Full control to make sure that your User Account has all the privileges.
• Now click on Apply and then OK.
• After that, delete the file you saw earlier which is named mcupdate_Genuine.dll.
• Then close all the Windows File Explorer instances and go back to the Command Prompt window and unmounts the image you mounted before by typing the following command:

dism /Unmount-Image /MountDir:C:UsersUserDesktopmount /commit

• Afterward, repeat the steps from mounting up until here for these files:
  • wim /index:2
  • wim /index:1
  • wim /index:2
• Now delete the mount folder and remove the USB Pen Drive and then boot with the installer.

Option 2 – Try to perform a Disk Cleanup

Chances are, some unnecessary files in your computer might be interrupting the installation process which explains why you’re getting SAFE_OS phase error during Replicate_OC operation instead so you need to perform a Disk Cleanup in order to fix the problem.

Option 3 – Try updating all your drivers

Every now and then, drivers get corrupted or outdated so it’s no surprise that they conflict with the operating system and cause errors like the SAFE_OS phase error during the Replicate_OC operation. To fix the problem, you need to update all your drivers. Follow the steps below to update your drivers.

• Tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. If you see a red or yellow sign that shows up against the driver, right-click on the driver’s name and select “Update Driver Software” or “Uninstall”. And if you find any “Unknown device”, you need to update it as well.
• Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
• Restart your PC.

Note: You also have the option to go directly to the website of your graphics card manufacturer and check if there’s a new update – if there is, download it.

Option 4 – Try to update your system’s BIOS

Aside from outdated drivers, outdated BIOS could also be the reason why you’re getting the SAFE_OS phase error during Replicate_OC operation which is why you need to update your system’s BIOS in order to resolve the issue.

Option 5 – Try checking the Windows Services status

• In the Cortana search box, search for “Services” and then click on the Services icon.
• After that, the Services utility will be opened in a new window.
• Next, look for the following services:
  • BITS (Background Intelligent Transfer Service)
  • Windows Update Service
  • Cryptographic Service
• Then right-click on each one of the services and click on Properties. From there, select Automatic from the drop-down of the Startup Type menu.
• Now click on OK for each one of them and restart your PC to apply the changes made.

Option 6 – Try to check the RAM modules

There are many times when all the components of the RAM weren’t able to be used by the computer so you need to check the RAM modules.

• You need to first turn off your PC and then take out your RAM physically.
• Next, clean it with a soft cloth and blow some air into the RAM slot in the motherboard.
• After that, put your RAM back in the same slot.
• Then try updating your computer system again.

Every computer has to have a graphic card, it is one of the essential components in order for the computer to work. If you have a second-hand computer, got one as a gift, or similar, there is a high chance that you do not really know which components are inside. Luckily finding out which graphic card you have inside is quite easy. Right-click the taskbar and select Task Manager Click the Performance tab at the top of the window, if you don’t see the tabs, click “More Info.” Select “GPU 0” in the sidebar. The GPU’s manufacturer and model names are displayed at the top right corner of the window. You’ll also see other information, such as the amount of dedicated memory on your GPU, in this window. Windows 10’s Task Manager displays your GPU usage here, and you can also view GPU usage by application. If your system has multiple GPUs, you’ll also see “GPU 1” and so on here. Each represents a different physical GPU.

Although there are several Windows 10 devices that are touchscreen-based, the mouse still remains to be an important part of usage for many users especially the ones who do some hardcore work on their Windows 10 computers or laptops. If you’re one of the users who often edit images or videos either for fun or work, using Touch is difficult as it’s a bit hard to drag on the screen so nothing really beats the mouse. However, as awesome as the mouse is, there are times when you encounter issues while using it. One of these issues is when your mouse pointer lags or freezes so in this post, you can try out a few tips that can help you resolve the issue.

Option 1 – Clean both the mouse and the mousepad

It might sound silly but it is a fact that either the mouse or the mouse pad themselves is the problem. Even though mouse balls are long gone, the laser lights that replaced them are not immune to some dirt which is why you need to clean the bottom of the mouse and then clean the mouse pad afterward.

Option 2 – Try changing the USB port

This is another basic thing you can do to resolve the problem since there are instances when USB ports where either your mouse is connected have gone rogue so you need to try switching to a different port and then see if the problem’s fixed or not.

Option 3 – Switch back to the default settings of the mouse

Switching your mouse back to its default setting is always a good idea since you are dealing with a pointer issue. To go back to the default settings of the mouse, here’s what you have to do:

• Click on Mouse and Touchpad.
• Next, click on Additional Mouse Settings located in the right pane.
• After that, click on the “Use Default” option under the Pointer tab.
• Then click on Apply and OK to save the changes made.

Option 4 – Try disabling Smooth Scrolling

You have to slow down both the horizontal and the vertical scrolling of the mouse in the settings which are called “Smooth scrolling”. This will help if you think that the websites you are visiting scroll up and down way too fast.

Option 5 – Try to update or rollback mouse drivers

If the first few options didn’t work for you, then it’s time to either update or roll back the mouse drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated the mouse driver then you need to roll back the driver. Whichever applies to you, refer to the steps below. The problem may be caused by a corrupted or outdated driver. So you have to update or reinstall the mouse driver. How? Follow these steps:

• Open the Devices Manager from the Win X Menu.
• Then locate the Mouse and other pointing devices and right-click on the mouse driver to open the Properties.
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, disconnect the mouse and plug it back in to reinstall the mouse driver.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 6 – Try to check if your laptop is turning off the mouse

In case you don’t know, the power management can turn off the devices that are not in use to save battery power if you use a laptop. And this can also happen on USB-based devices like the mouse. Thus, you need to verify if your laptop is turning off the mouse.

• Go to Device Manager > Universal serial bus controllers > USB Root Hub > Power Management.
• After opening Power Management, uncheck the “Allow the computer to turn off this device to save power” option.
• If you have lots of USB Root hubs, you can try changing each one of them and see if it works or not.

Option 7 – Try updating the Graphics Drivers

• Tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. If you see a red or yellow sign that shows up against the driver, right-click on the driver’s name and select “Update Driver Software” or “Uninstall”. And if you find any “Unknown device”, you need to update it as well.
• Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
• Restart your PC.

Note: You also have the option to go directly to the website of your graphics card manufacturer and check if there’s a new update – if there is, download it.

Option 8 – Try setting the No Delay option for Touchpad

If you are using a laptop that’s touchscreen-based, you can try setting the delay to zero in the settings. To do so, simply go to Settings > Devices > Mouse and Touchpad. From there, you can set the delay before clicks to “No Delay”.

Error Code 0x80070490 - What is it?

When downloading a Windows update, it is important to remember that these updates are what keeps your computer safe. Some users have reported seeing error code 0x80070490 when allowing updates for their Windows PC. This error code may appear when the user is trying to connect to the update site for Windows and maybe a result of a corrupted CBS manifest. Having this error code will not only stop the update of the system, but it will also certainly halt any work being done with the computer. Quite a few Windows users have written in complaints about this error while updating from any prior Windows update to Windows 10.

Common symptoms include:

• While a user is performing the updates, the Windows computer will stop running the updates, and it will show the error code 0x80070490.
• Windows updates will not install any new features and will not install security patches.
• The computer will not continue with the Windows update, and it may revert back to the previous state that the computer was in, prior to attempting the updates.

Error Causes

There is not a lot known about what exactly causes the error code 0x80070490, but it is something critical that makes Windows abruptly stop its updates. It could be caused by a simple glitch in the computer system, or it could be caused by a larger problem. One thought is that the CBS (Component-Based Servicing) manifest can be corrupt. Another thought is that the computer's anti-virus software may be interfering with the computer's ability to perform the necessary updates.

Further Information and Manual Repair

There is very little information known about error code 0x80070490 and why it exists, but there are a few methods in which to correct it. Users should be careful when trying to fix this error themselves. If the user feels that the methods are too complicated or they are uncomfortable taking it on themselves, they should contact a Windows repair technician to fix the problem. Not all methods listed will suit the user's needs, but it is dependent upon the problem at hand as to which method will be the best fit to fix the error code. If these steps are taken and the error is not corrected, it is vital to contact the Windows repair technician.

Method One: Creating a new local account

Create a new local account on the computer, and allow administrator privileges on it. Next, move all of your documents and personal files to the new account. Delete the old account (you will no longer be using this) and switch over to the new one. After switching to the new local account, add the Microsoft account to it.

Method Two: Delete user ID, Store cache from the registry

• You will need to open the Registry Editor. Do this by pressing the Windows Key and R, then typing in “Regedit”. After this is typed in, press Enter or click the OK button to start the registry editor.
• When this starts, you will need to navigate all the way to the following key on the left pane:
• HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionAppxAppxAllUserStore After this, find the key that is similar to this: S-1-5-21-1505978256-3813739684-4272618129-1016
• NOTE: this is just an example. The keys will be in a similar format but will not look exactly like this.
• Select all the keys that look like this, and then delete them. After these keys are deleted, close the Registry Editor and restart the computer.

Method Three: Check to see if BITS, MSI Installer, Cryptographic, and Windows Update Services are running

Press the Windows key and R. Then, type in services.msc. After the Services window starts up, find the following services:  BITS, MSI Installer, Cryptographic, and Windows Update Services.

Recently, several users reported an issue on their Windows 10 computers where the taskbar is not visible when they tried to connect to a computer via Remote Desktop Protocol or RDP. The Remote Desktop Connection feature uses the RDP which allows users to access a computer remotely. This is actually different from the taskbar being hidden automatically until the pointer hovers on it since, in this scenario, the taskbar is completely not accessible which makes using the remote computer entirely difficult, if not impossible. There are several suggestions you can check out to resolve this problem, you can try to restart the process of Windows Explorer via Task Manager or you could clear the cache for multiple processes. You could also try to reinstall the Shell Experience components or show the local taskbar in the Remote desktop. Moreover, you could also try to update, uninstall or roll back the display driver/graphics card driver. For more details, refer to each one of the options given below.

Option 1 – Try to restart the Windows Explorer process

The first option you have to try to fix the problem with the taskbar is to simply restart the Windows Explorer process in the Task Manager.

• Tap the Ctrl + Shift + Esc keys to open the Task Manager.
• Next, go to the Processes tab and find the process of Windows Explorer.
• Once you find it, right-click on it and select Restart to restart its process.
• After that, restart your computer and see if you can now see the Taskbar.

Option 2 – Try clearing the cache of multiple processes

The next thing you can do to resolve the problem is to clear the cache of many processes in your computer. To do so, follow these steps:

• Open the Notepad app and paste the following content in the text area:

@echo off taskkill /f /im explorer.exe taskkill /f /im shellexperiencehost.exe timeout /t 3 /NOBREAK > nul del %localappdata%PackagesMicrosoft.Windows.ShellExperienceHost_cw5n1h2txyewyTempState* /q timeout /t 2 /NOBREAK > nul start explorer @echo on

• After that, tap the Ctrl + S keys to save the changes you’ve made in Notepad and select the “All files” as its file type, and then name it “CacheClearTWC.bat”.
• Next, go to the location where you saved the file using File Explorer and then run it. This will run a couple of batch scripts which will clear the cache of multiple processes in the system.
• Tap the Win + X keys and select the “Windows PowerShell (Admin)” option to open PowerShell as admin.
• Next, execute this command in the command line: Get-appxpackage -all *shellexperience* -packagetype bundle |% {add-appxpackage -register -disabledevelopmentmode ($_.installlocation + “appxmetadataappxbundlemanifest.xml”)}
• After the command has been executed, this will reinstall the Shell Experience components and should fix the problem with the taskbar.

Option 4 – Update, uninstall or rollback the Graphics card drivers

• First, boot your computer into Safe Mode.
• After that, tap the Win + R keys to launch Run.
• Type in MSC into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. From there, look for the Display Adapters and click on them.
• After that, right-click on each entry under the Display Adapters and select the “Uninstall Device” option from the menu.
• Now restart your computer.
• After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.

Note: You also have the option to go directly to the website of your graphics card manufacturers like NVIDIA, Intel, or AMD and go to the section called Drivers then check if there’s a new available update – if there is, download and install it.

Reddit is one of the most popular websites in the world and how Microsoft is opening doors to everyone in its new store Reddit took a logical step and made a Progressive web application and placed it in it. Being a Progressive web app makes it more familiar and feels like a home experience using it for a lot of Reddit users. Reddit itself has a large community and active topics discussions all the time about anything. Bringing it to Windows as an application is, in my opinion, a great move since as an application it is independent, more light-weighted, and offering some other advantages specifically tied to being a standalone windows application. Everyone familiar with and using the Reddit website will feel right at home in this app and you can start using it right away.

It really sucks when you can’t fully enjoy the newest version of your favorite OS.

Windows 11 is still relatively fresh and consequently has some annoying little bugs that really ruin our experience. The good news is that you’re not alone and most of them are easy to fix.

Here are 5 commonly reported Windows 11 issues and what you can do to get rid of them.

1. Windows 11 audio problems

One of the absolute most irritating things in the world is struggling with the sound on your computer. Windows 11 users have reported facing the issue of low or no sound. If you’re currently experiencing the same frustration, you can be relieved. Chances are fixing it will only take a few minutes.

The first thing to check would be whether you accidentally muted your device by pressing the mute button on your keyboard. Yes, we know it sounds a lot like the old “have you tried turning it off and on again?” But it’s important to leave no stone unturned, and the most obvious things are usually the ones we easily overlook.

Moreover, if you have several audio output sources, check whether the right one is selected. You can do this via the Action Center or through Settings. If you want to use the same source every time, we also recommend you set it as the default one.

It’s also important to have a good, up-to-date audio driver. More often than not, this will be the true cause of your audio struggles. Make sure to update your driver, and if that doesn’t work out, you can always un- and reinstall it or install a different one. 

Lastly, if all attempts remain unsuccessful, run the audio troubleshooter to figure out what’s actually going wrong.

2. Unable to find files

Such a powerful new operating system, yet it can’t seem to do the simplest thing imaginable? The File Explorer not responding on Windows 11 is one of the most frustrating and most common problems with Microsoft’s newest iteration of its awesome OS.

However, 9/10 times it can be fixed by simply restarting your PC. You could also try killing the Windows Explorer process in the Task Manager and then rerunning it.

If these don’t help, check whether there are any pending Windows 11 updates. A single missing update can compromise your PC’s functionality, so always make sure to install them all on time. 

Should none of that work, then there are other ways to solve the File Explorer problem. However, then the issue is probably a bit deeper and it’s no longer in the ‘easy fix’ territory.

3. Start menu not working

Just like the File Explorer, the Start menu is a fundamental element of your OS. So, it’s only natural that its malfunction grinds your gears. It may be more customizable than on previous Windows versions, but it doesn’t always work smoothly. 

If you’re facing the so-called Start menu critical error, there are a few things this could be caused by. Usually it means you turned off your system while an important update was still being installed, there is a corrupt file on your PC, or Windows forcefully stopped a program. 

Whatever the reason, the solution should be pretty simple. Try the basic steps: restarting your File Explorer (like we explained above) and signing out and back into your account. If that doesn’t do anything, you may want to try uninstalling third-party start menu apps (if you have any), since they can interfere with your default programs’ functionality.

Now, those are the easy fixes. If you get nowhere with them, you might need to identify the root cause and search for more complex solutions than that.

4. Snipping tool not working

Our beloved screenshot tool was introduced with Windows 10 and Microsoft decided to keep it. However, you were probably just as disappointed as us when you tried to run it and failed. 

Normally, this can be fixed by installing the latest Out-of-band (OOB) update, or even pending updates in general. Even if your system appears to be up-to-date, run the checker just in case.

Another cool thing Windows 11 lets you do is ‘Repair’ and ‘Reset’, which is the easiest way to troubleshoot your Snipping tool. If this fails, you can also try the good old un- and reinstall method. Simply uninstall the tool through the Control Panel and reinstall it from the Microsoft Store.

Furthermore, in the case of an upgrade from Windows 10 to 11, it may be that the old Snipping tool version is interfering with the launch of the new one. If you don’t care that much about the additional options available with the enhanced screenshot tool, you can use the old version instead.

Simply go to your C Drive, find the Windows.old folder, search for the tool and open it from there. Make sure to pin it to your taskbar as well, if you know you’re going to use it often.

5. Can’t install the latest update

The latest Windows 11 version, 22H2, has brought tons of enhancements to our dearest operating system. Unfortunately, a lot of users still haven’t had the opportunity to experience it. A mere update of your OS version should be the one thing that goes smoothly, but sometimes that’s not the case.

Failure to install 22H2 can be caused by a few things. Most commonly, the issue is caused by lack of storage space or corrupted files, but there could be other culprits.

There are a couple of things you could try. For example, it’s crucial that your drivers be up-to-date and some important services be enabled. These are: Windows Modules Installer, Background Intelligent Transfer Service, Cryptographic Service, Windows Update services.

To enable them, search ‘Services’, find the service you need and right-click on it. Open ‘Properties’ and select the startup type ‘Automatic’.

It may also be necessary to unplug all peripherals that aren’t crucial and disable third-party antivirus tools until after the update is finished. 

Ultimately, you can run the Windows Update troubleshooter to detect and fix other possible issues.

Summary

Tiny bugs like these are nothing out of the ordinary. That said, we still all hate when they happen.

Hopefully some of our solutions have helped you to a smoother Windows 11 experience. But if you’re still struggling, feel free to reach out to us. We’d be happy to help!

As you know, Windows 10 has a complicated mechanism for Activation which helps in the verification of a genuine copy of Windows 10. However, there are times when you might encounter some errors during the activation process. One of these errors is the error code 0xc000f074. This kind of error could be due to the Key Management Service or KMS which is unreachable by the client computer or if the key used in the SLSetAuthenticationData function call is incorrect. This kind of error mostly affects surfaces on computers that are upgraded from either Windows 7 or Windows 8.1 to Windows 10. In such cases, you may encounter any of the following error messages:
