Hi,

It seems that after enabling the Unified Write Filter (UWF) on your Dell AIOs, you are encountering a black screen issue on reboot. This issue might occur due to a UWF servicing mode where UWF disables some system updates[^1]. To fix this issue, you can try the following:

1. Try accessing Windows recovery options by pressing the power button three times during the boot process. From there, select Troubleshoot > Advanced Options > Startup Repair. This may repair any damaged system files and resolve the black screen issue[^2].
2. If the issue persists, you can try disabling UWF and restarting the computer. Once the computer restarts, you can try enabling UWF and see if the issue is resolved. To disable UWF, run the command uwfmgr filter disable in Command Prompt with admin rights [^1].
3. If the above steps do not solve the issue, you can completely turn off UWF and create a new UWF configuration following the steps mentioned here [^2].
