Practical Solutions for Installing Windows Upgrade 11 KB5034765

In addition to installation problems, update KB5034765 introduced other bugs, including the disappearance of the taskbar. This is just one of the many glitches that Windows 11 users face with some regularity, despite extensive testing by Microsoft prior to the release of updates. Compatibility with all devices is never guaranteed, especially if the operating system is installed on unsupported hardware.

Identification and Removal of Folder $WinREAgent

One of the main causes preventing the installation of KB5034765 is the presence of the hidden $WinREAgent folder. This folder can interfere with the update process, but fortunately it can be eliminated through the following methods:

  • Using Disk Cleanup
    • Open “Disk Cleanup” as an administrator.
    • Select the system drive (usually C:).
    • Choose the Temporary Files option and any other relevant settings.
    • Confirm your selection and proceed to remove the files, including those within the $WinREAgent folder.

  • Manual Exploration and Deletion from File Explorer
    • Open File Explorer and navigate to the system drive.
    • Be sure to enable the display of hidden items in the folder settings.
    • Find the $WinREAgent folder and remove it manually, making sure to confirm the deletion if prompted.

  • Removal Via Command Prompt
    • Open the Command Prompt as an administrator.
    • Type the command rmdir /S /QC:\$WinREAgent and press Enter.
    • This command will remove the $WinREAgent folder, clearing the way for the upgrade.

Next Steps

After deleting the $WinREAgent folder, it is advisable to follow some additional steps to ensure a smooth installation of the update:

  • A simple restart can solve many problems related to updates.
  • Go to Settings > Update and Security > Windows Update and look for new updates. Update KB5034765 should now install smoothly.

If installation of update KB5034765 continues to fail despite deletion of the $WinREAgent folder, further troubleshooting actions, such as using the Windows Update troubleshooting tool or consulting Microsoft Technical Support, may be necessary. Keeping your operating system up-to-date is crucial to the security and performance of your device, so it is important not to neglect these updates.

Solution to Taskbar Problems in Windows 11 After Update KB5034765

Before proceeding with any solution, make sure your device is up to date. Go to Settings > Update and Security > Windows Update and check for new updates. Installing these may fix the problem without further action.

If the malfunction persists even after installing the latest updates, you may need to consider uninstalling update KB5034765. Here’s how to do it:

  • Open Settings and go to Windows Update.
  • Select Update History.
  • Click on Uninstall updates.
  • Find KB5034765 in the list, select it, and click Uninstall.
  • Confirm your choice and reboot your device once the uninstallation is complete.

After rebooting, it is advisable to recheck for updates in Windows Update to reinstall any necessary security patches, including a potentially corrected version of KB5034765.

If the above steps do not solve the problem, you might consider some alternative solutions such as:

  • Use a recovery point created before the installation of the problematic update (if available).
  • Sometimes, user profile-specific problems can cause similar malfunctions. Creating a new user profile can be an effective solution.

Fixing the crash of File Explorer and the disappearance of the taskbar

Update KB5034765 led to an increase in reports of File Explorer malfunctioning and the taskbar disappearing, compromising system usability. Microsoft acknowledged these problems and implemented server-side fixes to mitigate the impact on users.

The error manifests with a message indicating a problem with explorer.exe, specifying that “The instruction in 0x00007FFB20563ACa referenced memory at 0x000000000024. The memory could not be written.” This suggests a problem related to memory management by the application.

Resolution strategies

  • If you have a game controller, such as an Xbox 360 controller, connected to your PC, try unplugging it before rebooting or shutting down. Although the direct role of these devices in causing the problem is unclear, some users have noticed a correlation.
  • Make sure all drivers on your system, especially those for external devices such as game controllers, are up to date. Visit the device manufacturer’s site to download the latest version available.
  • Open the command prompt as administrator and type sfc /scannow to run a full scan of your system files for corruptions or errors and repair them automatically.
  • Use the Windows memory diagnostic tool to check for problems with your PC’s RAM. You can also consider using external tools such as memtest86+ for more in-depth analysis.
  • If none of the previous solutions solve the problem, consider doing a clean installation of Windows 11. This can eliminate any software conflicts or system corruptions that could cause File Explorer to crash.

Facing problems with Windows updates can be frustrating, but understanding the underlying causes of these glitches and knowing possible solutions can help mitigate the impact on our digital experience.
