Windows 11 and Windows 10 carry a number of features which help it optimize its performance on a given computer. When an error is encountered by the operating system, it has capabilities to provide proper resources to the user to get the issue fixed or just fix it by itself. Sometimes, even the user is not notified and an issue is either dodged or repaired in the background. One such feature is the Diagnosis of the Automatic Repair feature which starts when the PC is booting. At such times you will see a message – Diagnosing your PC or Preparing Automatic Repair. This feature has proven to be effective, but some users have been reporting that the fixing process gets stuck.

You will then have to power down your computer and boot Windows in Safe Mode. You can then carry out these fixes to get Windows 11/10 out of the stuck Diagnosing your PC, Attempting repairs or Preparing Automatic Repair screen. If you are unable to even boot into Safe Mode, then only the 4th option suggested below will help you.
