Hi, good day!
I'm sorry you're having trouble with Windows Update.
To help narrow down the cause, could you please provide a bit more information?
- Do you receive any error message or error code when the update fails?
- Does the PC restart and then roll back the update, or does it simply return to the "Download and restart" prompt without installing anything?
- Have you already tried any troubleshooting steps, such as running the Windows Update Troubleshooter or restarting your computer?
I look forward to receiving your update and I'm willing to collaborate with you till we resolve the issue. Do keep me informed by clicking "Add comment" below.
