Enumerating user sessions to generate ...

The Windows 10 operating system supports the logging in of multiple users at the same time. Aside from that, it also allows administrators to create a Guest Account that has limited rights. However, there are some instances when you could encounter an error when you use the Guest Account. The error may state:

“Shell Infrastructure Host has stopped working. A problem caused the program to stop working correctly. Please close the program”.

This error indicates that the Shell Infrastructure Host or SiHost.exe process that is used for handling graphical elements, has crashed. And to fix this error, there are several options you can check out. You can try to reinstall the Microsoft Redistributable Packages or run a System File Checker scan. In addition, you can also use a new Guest Account or troubleshoot the problem in a Clean Boot State.

Option 1 – Try to install or repair Microsoft Visual C++ Redistributable 2013

A corrupted Microsoft Visual C++ Redistributable package or the absence of it can trigger the “Shell Infrastructure Host has stopped working” error – so if you do not have this package yet, you have to install it but if you already have it, follow the steps below to repair it.

• Open Control Panel and proceed to Program and Features.
• Under Programs and Features, look for Microsoft Visual C++ Redistributable package among the list.
• Then right-click on it and click the Change button.
• Next, you should see the Repair option – click on it to repair the installation of the Microsoft Visual C++ Redistributable package.
• The process may take a couple of minutes before it finishes so once it does, you have to restart your PC.

After doing all these steps and you still encounter the problem, you might have to uninstall this package and download it directly from Microsoft’s website. However, if you are using Windows 10, you might not be able to do so since it only supports Windows versions up to Windows 8.1 so just proceed to the next option below.

Option 2 – Try to run a System File Checker scan

• In the Windows Start Search, type “command prompt” and right-click on Command Prompt from the search results, and then select the “Run as administrator” option.
• After opening Command Prompt with admin privileges, type the “sfc /scannow” and tap Enter to execute it.
• Once the scan is finished, restart your computer and see if the Windows Script Host error.

Option 3 – Try using a new Guest Account

You might want to use a new Guest Account as it could help get rid of the error. All you have to do is have your admin delete the old Guest Account and create a new one and see if it helps in fixing the error.

Option 4 – Try troubleshooting the problem in a Clean Boot State

Setting your computer in a Clean Boot State can help you diagnose and later troubleshoot the problems in your computer. During this state, the system will start with a minimal number of drivers and startup programs that help in isolating the problem with the interfering software. To put your computer in a Clean Boot State, follow the given steps below.

• Log onto your computer as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

Recently, a number of users reported that they were not able to use the “Run as administrator” context menu option when they tried using it or opening a program with administrator privilege. If you are one of these users facing this problem, then you’ve come to the right place as this post will guide you in fixing this issue. At the time of writing, it isn’t clear what the cause of the issue is but there are potential fixes you can try to fix the problem. You can try turning on the User Account Control or clean up the Context Menu items change the Group Membership. On the other hand, you can also perform both SFC and DISM scans via Command Prompt or troubleshoot the problem in a clean boot state as it is possible that some third-party programs are the ones that are causing the problem. You could also run an anti-malware scan using Windows Defender or your antivirus program.

Option 1 – Try to turn on the User Account Control

When you open a program with administrator privilege, the User Account Control or UAC prompt will pop up asking you to confirm the permission. However, if you have disabled the User Account Control by mistake or some malware has disabled it, then it’s no wonder why the “Run as administrator” option is not working. Thus, you need to check if UAC is turned on or not. All you have to do is go to the User Account Control settings.

Option 2 – Try changing the Group Membership

• First, you need to sign in with your administrator account or ask your administrator to sign in for you. So if you only have a Standard User account, you have to add that account to the Administrators group.
• In the taskbar search box, type “netplwiz” and check the search results.
• From there, select your user account and click the Properties button.
• After that, go to the Group Membership tab and select Administrator.
• Now click on the Apply and OK buttons to save the changes made and then sign in to your computer again and see if the “Run as administrator” option is working or not.

Option 3 – Try to create a new Administrator User account

If you have a standard account, you can try creating a new account but this time, you create an administrator user account and then see if you can now use the Run as administrator option or not. Note that you have to sign in with your main account before you can create an admin account.

Option 4 – Run the DISM tool

You can run the DISM tool as well to help fix the problem with the “Run as administrator” option. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 5 – Perform a System File Checker scan

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the problem with the “Run as administrator” option on your Windows 10 computer. SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow and hit Enter.

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Once done, restart your computer.

Option 6 – Put your computer in a Clean Boot State

You can also troubleshoot the problem in a Clean Boot state. It could be that there are some third-party applications in your computer that are preventing you from using the “Run as administrator” option and to isolate this possibility, you need to boot your computer in a Clean Boot State and then try to use the Run as administrator again. Putting your computer in this state can help you identify which program is the culprit and thus isolates the problem. In a Clean Boot state, your computer will start using only the pre-selected minimal set of drivers and startup programs. Note that you have to disable and enable one process at a time.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• After you’ve set your computer into a Clean Boot State, try to check if the error is now fixed and that you can now view the Properties.

Option 7 – Try scanning your computer using Windows Defender

As mentioned, if your computer was recently infected with some malware, it is possible that the malware changed the User Account Control settings which is why you’re not able to use the Run as administrator option. Thus, you need to scan your computer using Windows Defender.

• Tap the Win + I keys to open Update & Security.
• Then click on the Windows Security option and open Windows Defender Security Center.
• Next, click on Virus & threat protection > Run a new advanced scan.
• Now make sure that Full Scan is selected from the menu and then click the Scan Now button to get started.

As you know, the Taskbar is one of the integral parts of the Windows desktop and it has been there since the release of Windows 1.0 and up until now with Windows 10. Since then, Microsoft has been modifying the Taskbar with a new design which makes it a home for new features such as Windows Search, Task View, and many more. However, there are times when you may that the Taskbar has disappeared or has stopped responding. If you experience either one of these scenarios, read on as this post will walk you through what you can do to resolve the problem. Here are some suggestions you can check out to resolve the issue with the Taskbar in Windows 10 but before you proceed, make sure that you create a System Restore point first. To do that, follow these steps:

• In the Start search, type in “create a restore point” and click the entry “System Properties”.
• Next, select the main system drive under Protection Settings and click on the Configure button.
• After that, select the “Turn on system protection” option and then click on the Apply and OK buttons to save the changes made.

Once you’ve created a System Restore point, refer to the troubleshooting steps below to fix the Taskbar in Windows 10.

Option 1 – Try to restart the Explorer process

This may sound really basic but it actually is a proven method to fix the Taskbar issue. So if anything gets stuck on the system tray or the Taskbar, you can always fix it by restarting the explorer.exe. How? Refer to these steps:

• First, right-click on the Taskbar and select the Task Manager.
• After opening the Task Manager, go to the Processes tab and look for the process named “Windows Explorer”.
• Then right-click on that process and select the option to Restart. Afterward, you should now be seeing the Taskbar as this will reload the whole Windows Shell.

Option 2 – Unhide the Taskbar using the Settings app

It is possible that the Taskbar could be hidden so you can try to unhide it using the Settings app.

• Tap the Win + I keys to open Settings.
• After that, go to Personalization > Taskbar.
• From the main section, make sure that the “Automatically hide the task in desktop mode” is toggled to the off position. However, if it’s already off then proceed to the next options below.

Option 3 – Make sure that you are not in Tablet Mode

Since Windows 10 is designed to work on both desktop and mobile devices, it could be that your computer has slipped into Tablet Mode which explains why you’re not seeing the Taskbar. To check if your computer is really in Tablet Mode, follow these steps:

• Go to the Start menu and select Settings.
• Next, select the System setting and from the left pane select the Tablet Mode.
• From there, make sure that the buttons next to the options given below are set to the off position:

• Tap the Win + P keys to open the Windows Projection settings.
• Next, make sure that you select the “PC screen only” option and then check if your Taskbar has now appeared or not.

Recently, a lot of users reported getting several error messages when they upgraded their Windows 10 computers. One of these error messages users encountered during a Windows 10 upgrade is the Error 0x8007002C-0x4001E. if you are one of the users who is facing this error, read on as this post will help you fix it. When you encounter this error, you will see the following error message on your screen:

“We couldn’t install Windows 10 We’ve set your PC back to the way it was before you started installing Windows 10 0x8007002C-0x4001E, The installation failed in the SECOND_BOOT phase with an error during PRE_OOBE operation.”

To resolve the 0x8007002C-0x4001E, The installation failed in the SECOND_BOOT phase error, here are some suggestions that might help.

Option 1 – Try flushing the SoftwareDistribution and Catroot2 folders

You have to stop a couple of services such as BITS, Cryptographic, MSI Installer, and Windows Update Services. And to do that, you need to flush the contents in the SoftwareDistribution folder. The Software Distribution folder in the Windows operating system is a folder that can be found in the Windows directory and is used to store files temporarily which might be required to install the Windows Update on your PC. Thus, it is required by the Windows Update and maintained by WUAgent. Aside from that, it also contains all the Windows Update History files and once you delete them, you will most likely lose the Update history. As a result, the next time you run the Windows Update, it may result in a longer detection time.

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net start cryptSvc net start bits net start msiserver

• After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic, and the MSI Installer
• Next, go to the C:\Windows\SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.

After flushing the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:

• Type each one of the following commands.

net start wuauserv net start cryptSvc net start bits net start msiserver

• After that, exit Command Prompt and restart your computer, and then try to run Windows Update once more.

Option 2 – Select the Keep your files option

You can also select the option to perform an in-place upgrade and opt for the “Keep my files” option during an installation as it might make the process a lot smoother and if you need to perform a clean install, you can do so once the setup is completed.

Option 3 – Try to run the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter could also help you resolve the 0x8007002C-0x4001E, The installation failed in the SECOND_BOOT phase error. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button.

Option 4 – Try to run Microsoft’s online troubleshooter

Aside from the Windows Update Troubleshooter, you can also run the online troubleshooter of Microsoft as it can help you with Windows 10 upgrade errors.

Option 5 – Perform a clean install

If none of the options worked, you can try to clean install Windows 10. Just make sure that you have the ISO from the official Microsoft Website and then a bootable USB drive to install Windows 10 again. Take note that this will delete all the data from your drive where Windows 10 was installed previously.

If you got an Activation Error 0xC004F211 after having installed or upgraded your Windows 10 PC, then this indicates that some hardware in your computer has changed which’s causing the error to pop up. Windows might not be able to determine if the key is used on a new computer or if it’s still the same one if you have just removed or upgraded old hardware. But worry not for this post will guide you in fixing the Windows Activation Error 0xC004F211 on your Windows 10 computer. When you encounter this error, you will see the following error message on your screen:

“Cannot activate Windows 10. Try activating again later. If that doesn’t work, contact support. Error code: 0xC004F211.”

Note that although hardware changes cause this error, the minor ones don’t really cause any issues with activation, however, if you have made any significant hardware change such as replacing your motherboard, it will most likely cause the activation error. In such cases, the Windows Activation system will treat this as new hardware and you will need a new license for that. Even if your Windows 10 computer has a genuine key, it might still fail to get activated which results in the Windows Activation Error 0xC004F211. Thus, before you do other troubleshooting steps, you need to run the Windows 10 Activation Troubleshooter first. To do so, follow these steps:

• Go to Settings and then select Activation.
• After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

In addition, there is an exception offered by Microsoft – if you are connected to a Microsoft account prior to the hardware change, then you can most certainly use the same license key to reactivate Windows 10 again. Microsoft calls this an “Exception path” which should be fixed easily by the Windows Activation Troubleshooter as pointed out earlier. However, if the Windows Activation Troubleshooter isn’t able to resolve the error you can try purchasing a new license. In such rate case, even if you do have a Microsoft account available on your Windows 10 computer, and if Windows was never activated, this solution will not work. And if you haven’t connected your Microsoft account with your Windows 10 computer prior to the major hardware change, then your only option left is to purchase a new license. For you to do that here are some steps you can follow.

• To purchase a new Windows license, the first thing you have to do is click on the Start button > Settings > Update & Security.
• From there, go to Activation and select the “Go to Microsoft Store” option.
• After receiving your new license, you need to go back to Update & Security then go to Activation and select the “Change product key” option.
• Now update your Windows 10 computer using the new key and it should automatically activate your computer.
• Next, you have to create a Microsoft account or connect your existing local account to your online account.
• Once the system links the key and the account, you need not buy a new license in case something like this happens again.

Note: If you are an IT administrator, you need to keep in mind that there is a limit to the number of times you can reactivate Windows on your computer. Moreover, if you don’t see any option to reactivate the license, and it is a work computer, you need to contact your organization’s tech support.

Cyclic Redundancy Check Error - What is it?

To begin with, Cyclic Redundancy Check is basically an error checking technique. This technique is used for data verification. It detects accidental changes in the data. It is used by computers to specifically check the data stored in the hard drive or optical disks (DVD’s and CD’s). The Cyclic Redundancy Check error occurs when the data being verified on the hard drive or optical disks is corrupt. Symptoms for this error code include program lock-ups, slow PC performance, inability to run and execute the desired program, system freeze and shutdown and startup issues.

Error Causes

The Cyclic Redundancy Check error code occurs due to the following reasons:

• Cluttered hard disk
• Registry corruption
• Misconfigured files
• Unsuccessful program installation

All these causes points towards registry issues and poor PC maintenance. The registry is the main database of the computer. This part of the PC saves practically every activity you perform on it including activities like application installation and deletion and web browsing to name a few. With time and frequent PC usage, the files generated from every activity you execute on your system begin to load the registry. These include even the unnecessary files like junk files, internet files and files of applications that you’ve uninstalled. All these files overload the registry and acquire a lot of hard disk space. And when you don’t remove these files on your system, eventually it leads to file misconfiguration, cluttered disk, and registry corruption. New program versions that you want to install and run on your system also don’t function because the files of the old program version still saved in the registry.

Further Information and Manual Repair

As the Cyclic Redundancy Check Error causes data corruption on the hard disk, it is advisable to fix this error right away. The reason is that it can have serious consequences. It can lead to data loss, fatal crashes, and system failures. When it comes to resolving Cyclic Redundancy Check Error, there are two ways to fix it:

Run the CHKDSK application.

This is a built-in feature in your Windows system. It checks for hard disk damage and attempts to resolve it.

Each time when you press WINDOWS + PrtScn key on your keyboard a screenshot is taken and saved on your Hard drive, to be more precise, it is saved in a specific folder which is in c:\Users\Your user name\Pictures\Screenshots. Now, this specific location is not anything that's bad but it is a little deep and not so user-friendly for quick access.

Luckily this default location can be changed into any folder that you like.

Changing location

First thing is to open File Explorer and then navigate to your PC. Once you go to your PC, go to Pictures, and inside right-click on the Screenshots folder. If there is no screenshots folder inside, this means that since Windows was installed no screenshots were taken with WINDOWS + PrtScn key combination. Please note that just by pressing PrtScn you will create a screenshot but you will place it inside the clipboard ready to be pasted somewhere, with WINDOWS + PrtScn you are saving the screenshot directly in a file on your hard drive.

So once you clicked on the Screenshots folder, go to the bottom and click on properties. Inside properties go to the Location tab. In the location, tab clicks on MOVE and browse to your new location where you would like screenshots to be saved. Once you select the folder for screenshots, click on the Select Folder button and confirm with OK. After this, Windows will ask you would you like to move existing screenshots into the chosen folder. Click YES or NO, depending on your preference.

After this easy setup, all of your new screenshots will be placed now inside the chosen folder.

Thank you for reading and I hope to see you tomorrow. Take care.

As you know, the functioning of the Windows Sandbox feature is supported by various components in the background of the Windows operating system. And the only way for you to enable the Windows Sandbox feature in your computer is through the Turn Windows features on or off utility. This feature will work directly on the basis of Virtualization which is also supported by Hyper-V. However, there are some reports claiming that some computers have the Windows 10 Sandbox item greyed out in the Turn Windows features on or off utility. Thus, in this post, you will be guided on what you can do to resolve such a problem in your Windows 10 computer. In this kind of problem, you should know that this has something to do with the Second Level Address Translation which is one of the important pillars of how the Windows 10 Sandbox feature functions. Thus, if the Second Level Address Translation or SLAT feature in Windows Sandbox is not supported by the CPU of your computer, there is no way for you to use Windows Sandbox on your computer. On the other hand, if SLAT is supported, then there is definitely something you can do to resolve the greyed-out Sandbox item in Windows 10.

To get started, follow the steps provided below.

Step 1: First, you have to boot into the BIOS of your PC. Step 2: After that, make sure that the following options are set to their respective configurations:

• Hyper-V – Enabled
• VM Monitor Mode – Yes
• Virtualization – Enabled
• Second Level Address Translation (VT-d or RVI) – Enabled
• Data Execution Prevention – Enabled

Step 3: Once you’re done, save the configuration and then restart your Windows 10 computer as usual. Step 4: Once your computer has restarted, you should see the same option in the Turn Windows features on or off utility and it should no longer be greyed out. Then you can now enable the feature and follow the onscreen instructions need to use the feature as best as you can.
