There are many times when you have to change the ownership of a folder or a file so that other users can use them as well or if you want to transfer files to them, or an old account has been removed and all the files need to be assigned to a new user. Windows 10 keeps all these files locked under the account by default which created a folder or file. So unless a user is an admin or if the file belongs to that particular user, other users won’t be able to access or edit the file. So if you want to change the ownership of a folder or a file, then you’ve come to the right place as this post will guide you on how exactly you can do that.

To get started, make sure to follow the instructions provided below carefully.

Step 1: First, you need to open File Explorer by tapping the Win + E keys. Once you’ve opened it, navigate to the folder or file that you want to change the ownership. Step 2: Right-click on the folder or file and click on Properties and then go to the Security tab. Step 3: From there, click on the Advanced button located at the bottom right part of the window to open the Advanced Security Settings of the folder or file. Step 4: As you can see, the current owner will be listed with the Change link available next to the “Owner” label. Now click on this link to open the Select User or Group window. Step 5: After that, click on the Advanced button once again and click on the “Find Now” button to see the list of all the users as well as groups that are available in the computer. Step 6: Then select the user you want to give ownership to and click on the OK button and then click the OK button once more to save the changes made. Step 7: This will take you back to the Advanced Security Settings window but this time, the owner will be changed to whoever user you’ve selected. But you’re not done yet as you still have to check two additional options to help you completely transfer the ownership of the sub-folders as well as the files. You have to check the checkbox of the following options:

• Replace owner on sub-containers and objects
• Replace all child permission entries with inheritable permission entries from the object.

Step 8: After that, you need to click the Apply and OK buttons to confirm and save the changes made. This will completely transfer the ownership of the file. However, there is still one last thing you have to do – you have to go back to the Advanced Security Settings window to remove the access of any other user on the folder or file. Once you’re there, remove the existing user to make sure that the only assigned user has the access to the folder or file.

If you have multiple keyboards, things can get quite tricky. There are times when the keyboard language changes on its own since the keyboard changes while you are typing. The thing is, the keyboard changes because sometimes we accidentally tap shortcuts like Win key + Space key or Alt + Shift or Ctrl + Shift which changes the keyboard pairs or language. Thus, if your keyboard language changes on its own, there are two ways to resolve it. First, you have to make sure that Windows 10 does not add keyboards without your permission. Second, you have to make sure that the shortcut keys don’t change the keyboard language. This second option is what we’re going to discuss in this post. You need to first set a different input method for each app window. To do that, you have to disable the change in layout. Refer to these steps:

• Go to Settings > Language and input.
• Next, type “switching input methods” to open the Advanced keyboard settings with this option inside.
• After that, select the checkbox labeled as “Let me set a different input method for each app window” and then click the Save button.
• Restart your computer.

Now that you’ve disabled the change in layout, you now have to find the keyboard settings. Just go to Settings > Devices > Typing > Advanced Keyboard settings. From there, you have the option to select which keyboard is going to be used for any app. When you change the keyboard every time you use an app, usually, Windows remember it so that you won’t have to set it up all over again. In addition, the Advanced keyboard settings page also allows you to override the default input method which could be different from the first one in your language list. Aside from that, there is also a Language bar option that comes in handy as you can quickly switch between keyboards. And if you removed it, you have the option to restore the language bar back as well. Now all that’s left for you to do is to change the Language Settings under the Administrative tab. A user from a forum that came up with this solution, reported that the issue occurred when he started typing in some program with non-Unicode characters which caused Windows to use the default system local language to interpret these characters even though the language is unavailable in the Language bar. To change the Language Settings under the Administrative tab, follow these steps:

• Go to Settings > Time and Language > Language > Administrative language settings.
• After that, click on Copy Settings under the Administrative tab.
• Now make sure that all the Display language, Input language, and Format are English (United States) or any language you prefer.
• Then mark the two checkboxes in “Copy your current settings to Welcome screen and system accounts & New user accounts”.
• After that, click OK and then exit.

Note: You also have the option to disable those shortcut combinations which can change your keyboard settings accidentally.

In previous versions of Windows changing the system, the font was a pretty straightforward process, but it seems Microsoft did not want this feature to keep for whatever reason and there is no option as of the time of the writing of this article to do it in standard options in Windows 10. But do not worry, you are still able to customize your Windows and choose which font would you like to see inside it in all of its dialogs. You can choose whichever font you desire, the only prerequisite is it to be installed on your system. This guide will require you to change values in the registry of Windows itself so please follow step-by-step instructions and always make a backup of the registry before changing it in order to prevent some permanent Windows issues. All of that being said, let's start.

Setting new font

First thing is to open notepad, in the notepad paste the next block of code:

Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts] "Segoe UI (TrueType)"="" "Segoe UI Bold (TrueType)"="" "Segoe UI Bold Italic (TrueType)"="" "Segoe UI Italic (TrueType)"="" "Segoe UI Light (TrueType)"="" "Segoe UI Semibold (TrueType)"="" "Segoe UI Symbol (TrueType)"="" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes] "Segoe UI"="NEW_FONT"

Where in "Segoe UI"="NEW_FONT" instead of NEW_FONT you need to write the exact name of the font that you wish to use as a system font. Once you have replaced the default system font with your desired one, go to File and save as, from file type drop-down menu, choose all files and save this file as .REG type giving it whatever name you wish. When the file is saved, close notepad, right-click on the saved file and choose the merge option. Confirm with YES and click on OK. Reboot your system and your Windows will now use the font of your choice as its default system font.

Restoring default font

If you wish to return the old default system font as it was, follow the same steps but in your notepad paste this code:

Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts] "Segoe UI (TrueType)"="segoeui.ttf" "Segoe UI Black (TrueType)"="seguibl.ttf" "Segoe UI Black Italic (TrueType)"="seguibli.ttf" "Segoe UI Bold (TrueType)"="segoeuib.ttf" "Segoe UI Bold Italic (TrueType)"="segoeuiz.ttf" "Segoe UI Emoji (TrueType)"="seguiemj.ttf" "Segoe UI Historic (TrueType)"="seguihis.ttf" "Segoe UI Italic (TrueType)"="segoeuii.ttf" "Segoe UI Light (TrueType)"="segoeuil.ttf" "Segoe UI Light Italic (TrueType)"="seguili.ttf" "Segoe UI Semibold (TrueType)"="seguisb.ttf" "Segoe UI Semibold Italic (TrueType)"="seguisbi.ttf" "Segoe UI Semilight (TrueType)"="segoeuisl.ttf" "Segoe UI Semilight Italic (TrueType)"="seguisli.ttf" "Segoe UI Symbol (TrueType)"="seguisym.ttf" "Segoe MDL2 Assets (TrueType)"="segmdl2.ttf" "Segoe Print (TrueType)"="segoepr.ttf" "Segoe Print Bold (TrueType)"="segoeprb.ttf" "Segoe Script (TrueType)"="segoesc.ttf" "Segoe Script Bold (TrueType)"="segoescb.ttf" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes] "Segoe UI"=-

Reboot your system and your Windows will now revert the font of your choice as its default system font.

As you know, the Start Menu in Windows 10 is quite a stable experience. However, there are times when it can encounter some issues as well like getting corrupted. If your computer is going through the same problem, you’ve come to the right place as this post will guide you on how you can fix the “Tile Data is corrupt” error. This kind of problem is actually quite common among a lot of Windows 10 users. This kind of problem prevents the Start Menu from working properly and no amount of clicking the keyboard keys or mouse will resolve the issue. Fixing it is important since the Start Menu is required for the operating system to function properly and even though there are several ways to get around in using the Start Menu, it can get quite problematic. Even if you manage to open the Start Menu, the ability to click on apps to open them is out of the question and you need to fix the problem. Worry not for the potential fixes provided in this post are not hard to follow. You can try to run the Start Menu troubleshooter or run the DISM tool. You could also reset the folder for Tile Database or re-register the Windows 10 Start Menu. For more details, refer to each one of the options provided below.

Option 1 – Try running the Start Menu troubleshooter

The first and basic thing you can do to fix the problem is to run the Start Menu troubleshooter as it can help you fix the problem automatically. Since this is not a built-in troubleshooter, you can download it from the official website of Microsoft. After you download it, run it and wait until it’s done identifying the problem and automatically fixing it.

Option 2 – Try running the DISM tool

You can run the DISM tool as well to help fix the “Tile Database is corrupt” error. 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
  • Dism(.)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.
• Once it’s done, check if it was able to fix the corrupted Start Menu or not.

Option 3 – Try to reset the Tile Database folder

• First, you need to restart your computer and log into another user account where the Start Menu works.
• Next, navigate to this folder location, C:/Users/<userX>/AppData/Local/Tile/DataLayer.
• From there, copy the “TdlData.xml” file and save it to another drive.
• Once done, restart your computer and log into the user account where the Start Menu is corrupted.
• After that, navigate to this folder location, C:/Users/<userY>/AppData/Local/Tile/DataLayer.
• Now paste the TdlData.xml file you copied earlier and navigate to this location, %LocalAppData%MicrosoftWindowsShell.
• Afterward, copy the DefaultLayouts.xml file from the user account that’s working fine to the user account where the Start Menu is corrupted.

Option 4 – Try to re-register the Windows 10 Start Menu

• Tap the Win + X and select the “Windows PowerShell (Admin” option from the menu.
• After opening PowerShell, execute this command: Get-AppXPackage -AllUsers |Foreach{Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)AppXManifest.xml"}
• Wait until the command is executed and then see if it fixed the problem with the Start Menu or not.

There are times when the WMI Repository gets corrupted which results in the Provider Load Failure. To resolve this issue, you need to repair or rebuild the WMI Repository in your Windows 10 computer. In this post, you will be guided on how exactly you can do that. In case you don’t know, the WMI which stands for Windows Management Instrumentation is a set of specifications from Microsoft to consolidate the management of devices and applications in a network. The WMI is a database that stores meta-information and definitions for WMI classes. Using only these, the conditions of the systems can be known. You can find the WMI Repository in %windir%System32WbemRepository. It provides end-users with the status of the local or remote computer system. Keep in mind that you must not use this on the Server 2012 Cluster machine. Although there are command-line tools that can fix or restore the Windows Management Instrumentation repository. However, Microsoft suggests that it’s better if you verify if there is corruption. Here are a list of errors as well as permission issues you might encounter:

• Unable to connect to root default or rootcimv2 namespaces. It fails with the error code “0x80041002” pointing to “WBEM_E_NOT_FOUND.”
• 0x80041010 WBEM_E_INVALID_CLASS
• When you open Computer Management and Right Click on Computer Management (Local) and select Properties, you get the following error: “ WMI: Not Found” or it hangs trying to connect
• Trying to use wbemtest , and it hangs
• Schemas/Objects missing
• Strange connection/operation errors (0x8007054e)

To verify if there is corruption, you can try running the following command in an elevated Command Prompt:

winmgmt /verifyrepository

 After you enter the command, if there is a response saying, “repository is not consistent”, then the repository has an issue. If not, then something else is causing the problem. Since you are certain that corruption exists in the WMI repository, then here are some suggestions you need to check out to repair or rebuild the WMI repository.

Option 1 – Try to reset WMI Repository

• Type “command prompt” in the Start Search and right-click on Command Prompt from the search results and then select “Run as administrator”.
• After opening Command Prompt with admin privileges, type and enter this command: winmmgmt /salvagerepository

The command you entered is used when the winmmgmt command performs a consistency check. So if an inconsistency is detected, it will rebuild the repository.

• Next, execute this command to see if the WMI repository now comes back as consistent: winmgmt /verifyrepository

This command will perform a consistency check on the WMI repository.

• If it states that the WMI repository is not consistent, then you need to type and enter this command: winmgmt /resetrepository

This command is used to reset the repository to its initial state when the operating system was first installed.

Option 2 – Try to force recover the WMI Repository

The WMI Repository comes with a built-in self-recovery process so when the WMI service restarts or detects any corruption, it will automatically trigger the self-recovery procedure. This can happen in two ways:

• AutoRestore: This will use the backup images if the Volume Shadow copy or VSS backup is turned on.
• AutoRecovery: The rebuilding process will generate fresh images of the WMI repository based on the registered MOFs. The MOFs are available in the registry located at HKLMSoftwareMicrosoftWBEMCIMOM: Autorecover MOFs

Note: Autorecover MOFs is a key so double click on it to check its value. On the other hand, if the self-recovery procedure does not work, you can try to use the force-recovery process instead. How? Refer to these steps:

• First, you need to check the reg key value is empty or not under this registry path: HKLMSoftwareMicrosoftWBEMCIMOMAutorecover MOFs
• If the reg key value is empty, you have to copy-paste the reg key value from another computer. Just make sure that it’s from the System which is equivalent to the computer in question.
• Next, type and enter this command: Winmgmt /resetrepository
• After you enter the command, if you get an error that says, “WMI repository reset failed. Error code:0x8007041B. Facility: Win32”, then you have to stop all the Dependency Services on the WMI service by running the following commands:
  • net stop winmgmt /y
  • Winmgmt /resetrepository

This should fix the problem.

If you suddenly encountered the PDC WATCHDOG TIMEOUT BSOD Blue Screen stop error with a bug check value of 0x0000014F, then it’s probably due to a system component that has failed to respond with the allocated period which prevents the system from exiting connected standby. This kind of Blue Screen error could be caused by both hardware and software components. To fix this Stop error, here are some possible fixes you can try that might help but before you proceed, make sure that you create a System Restore point first and boot your computer into Safe Mode with Networking.

Option 1 – Try to rollback, update or disable drivers

The next thing you can do to fix the PDC_WATCHDOG_TIMEOUT Stop error is to roll back, or update, or disable device 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 your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Open the Devices Manager from the Win X Menu.
• After opening the Device Manager, look for the device driver named “IDE ATA/ATAPI controllers” and expand it.
• Then look for the SATA AHCI Controller entry and right-click on it. If you haven’t updated this driver in a while, select the “Update Driver” option. On the other hand, if you’ve just updated this driver, then select the Uninstall Device option.
• Next, follow the screen option to update or uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically if you have chosen to uninstall them.

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 2 – Try to disconnect or disable newly installed hardware

In this option, you will have to disable or remove the hardware you’ve just installed recently since external devices could be the one that’s causing the Blue Screen of Death error to appear. To do that, just disconnect any external device that’s connected to your computer physically and then check if it fixes the PDC_WATCHDOG_TIMEOUT Blue Screen error.

Option 3 – Try running the Memory Diagnostic Tool

The Memory Diagnostic tool in windows can help resolve the PDC_WATCHDOG_TIMEOUT Blue Screen error by checking and automatically fixing any memory-based issues. To run it, refer to these steps:

• Tap the Win + R keys to open Run and type mdsched.exe and hit Enter to open the Windows Memory Diagnostic Tool.
• After that, it will give two options such as:
  • Restart now and check for problems (Recommended)
  • Check for problems the next time I start my computer
• Once your computer has restarted, perform a basic scan or you could also go for the “Advanced” options such as “Test mix” or “Pass count”. Simply tap the F10 key to start the test.

Option 4 – Try to update the BIOS

Updating the BIOS can help you fix the PDC_WATCHDOG_TIMEOUT BSOD error but as you know, BIOS is a sensitive part of a computer. Even though it is a software component, the functioning of the hardware depends on it largely. Thus, you must be careful when modifying something in the BIOS. So if you don’t know much about it, it’s best if you skip on this option and try the other ones instead. However, if you are well-versed in navigating the BIOS, then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “msinfo32” in the field and press Enter to open System Information.
• From there, you should find a search field on the bottom where you have to search for the BIOS version and then press Enter.
• After that, you should see the developer and version of the BIOS installed on your PC.
• Go to your manufacturer’s website and then download the latest version of BIOS on your computer.
• If you are using a laptop, make sure that you keep it plugged in until you have updated the BIOS.
• Now double click on the downloaded file and install the new BIOS version on your computer.
• Now restart your computer to apply the changes made.

Option 5 – Try running the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like PDC_WATCHDOG_TIMEOUT. It can be found in the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Microsoft allows its users to download a copy of Windows to install on PCs. However, when you enter the key after the installation and you got the Activation Error 0xC004F212 instead, then it means that the license key and the Windows version you’ve just installed, do not match. When you encounter this error, you will see the following error message on your screen:

“The product key used on this PC didn’t work with this edition of Windows. Activation Error 0xC004F212.”

Every time Microsoft generates a license for a copy of Windows, it is associated with one particular Windows variant. Windows comes in many editions like Enterprise, Home, Professional, and so on. For instance, if you bought a license for Windows 10 Enterprise but you have installed Windows 10 Professional instead, then the activation will surely fail and you’ll encounter the Activation Error 0xC004F212. You will be asked to select which edition you want to install when you reinstall Windows 10 using a digital license. If you opted for an edition other than the one you are licensed to use, then you will most likely get the Activation Error 0xC004F212. If you have purchased your license key from a store or some website, you might want to check back with them about the exact version of Windows. Doing so will help you narrow down the problem. And if you have second thoughts about the license key’s validity, you can just reach out to a Microsoft Support agent to check the validity of the license key. Also, if have bought it from the store, there should be an option to get a refund. That way you can choose to buy the right version of Windows.

Option 1 – Try running the Windows 10 Activation Troubleshooter

The first thing you can do to resolve the Activation Error 0xC004F212 is to run the Windows 10 Activation Troubleshooter. 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.

The Windows 10 Activation Troubleshooter will determine if your license key is a valid Windows 10 digital license for an edition that is not currently installed. If it turns out that it’s not, then the troubleshooter will show you how to install the correct edition.

Option 2 – Try forcing Windows 10 ISO to use the right version

You can also try to force Windows 10 ISO to use the correct version depending on the product key. Note that this option only works between Windows 10 Home and Professional version since they both have a common ISO. So if it’s Enterprise, then this option won’t work for you.

• Extract the Windows 10 ISO files using an extractor.
• Then browse to the folder you created and go to the sources folder.
• From there, you need to create a text file named “PID.txt” and make sure to follow the exact format given below:

[PID] Value=xxxxx-xxxxx-xxxxx-xxxxx-xxxxx

Note: “xxxxx” is the KEY to your Windows version.

• Next, you need to create the ISO again or bootable media that will repack everything and then create the Media file. You can use the Media Creation tool for this.

Note: Windows will check the key during the installation and will figure out the right version of Windows.

Option 3 – Contact Microsoft Support for assistance

If you’re at your wits’ end in trying to update your Windows 10 computer, you should consider contacting Microsoft Support for help as they can offer you various options that would make fixing Windows Activation Error 0xC004F212 a lot easier and faster.

In case you don’t know, Windows 10 supports installation and use of a number of removable devices which includes plug and plays mouse, keyboard, and other USB-based devices. But this could actually pose a threat to the integrity of a computer system and thus, some organizations pose a restriction in using these kinds of devices. the restriction on these devices is also useful especially if you keep on leaving your computer idle and someone tries to mess it up by plugging in a removable device. In such situations, the restriction will defend the user against data theft. Thus, in this post, you will be guided on how you can prevent the installation of removable devices on your Windows 10 computer. There are two options that can help you in preventing the installation of any removable devices on your computer – you can either try to use the Registry Editor or use the Group Policy Editor instead. Follow whichever option you want to use the instructions given below but before you start, don’t forget to create a System Restore Point first.

Option 1 – Prevent installation of Removable Devices via Registry Editor

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and hit Enter to open the Registry Editor.
• Next, navigate to this registry path: HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsDeviceInstallRestrictions
• From there, look for a DWORD named “DenyRemovableDevices” and set its value to “0”. On the other hand, if you can’t find this DWORD, just simply create it and set its value to 0.
• Once done, exit the Registry Editor and reboot your PC to apply the changes made.

Option 2 – Prevent installation of Removable Devices via Group Policy Editor

Keep in mind that the Group Policy Editor is not available in the Home Edition of the Windows operating systems. Thus, if you are using one, just stick to the first option, otherwise, proceed to the following steps.

• Tap the Win + R keys to open the Run utility and type “gpedit.msc” and click OK or tap Enter to open the Group Policy Editor.
• After that, go to this policy setting: Computer ConfigurationAdministrative TemplatesSystemDevice InstallationDevice Installation Restrictions
• Next, look for the “Prevent installation of removable devices” entry and once you find it, set it as “Enabled”. From this window, you should see the following description of this policy setting:

“This policy setting allows you to prevent Windows from installing removable devices. A device is considered removable when the driver for the device to which it is connected indicates that the device is removable. For example, a Universal Serial Bus (USB) device is reported to be removable by the drivers for the USB hub to which the device is connected. This policy setting takes precedence over any other policy setting that allows Windows to install a device. If you enable this policy setting, Windows is prevented from installing removable devices and existing removable devices cannot have their drivers updated. If you enable this policy setting on a remote desktop server, the policy setting affects redirection of removable devices from a remote desktop client to the remote desktop server. If you disable or do not configure this policy setting, Windows can install and update device drivers for removable devices as allowed or prevented by other policy settings.”

• Then click the Apply and OK buttons to save the changes made.
• Now restart your computer to save the changes made. This should prevent the installation of any removable devices in your Windows 10 computer.
