If the issue still persist, please perform In-place Repair/Upgrade.

In-Place Repair

• In-place repair/upgrade or repair reinstall is a process of re-installing Windows without touching any of your applications or personal files. In this way if there's any data corruption, damaged system files or missing system files on your computer, this repair will fix or repair them.

To start we need to download an ISO file of Windows 11 and save it to your computer. Please follow the instruction on the link below to create an ISO file

After the ISO is created, follow the steps below on how to perform repair install on your computer.

Note: Please make sure that you're signed in or have administrator rights to be able to proceed for the repair install.

1. Unplug all external hardware except mouse, keyboard and LAN cable.
2. Disable or uninstall any third-party antivirus program/application to prevent them from interfering with the repair install.
3. Run the ISO file that you downloaded, if there's a prompt asking you "Do you want to allow this app to make changes to your device?" Click Yes
4. Windows 11 setup will open, read the license terms then Click Accept button.
5. Select Upgrade PC now then click Next button.
6. Follow the steps on your screen.

This process will take some time to complete so you need to be very patient in waiting until the process completes. Once done, restart your computer and check if the issue is resolved.

Hope this help. Have a good day.

Thank you,

Jerico T.
