Issue: How to fix Windows is stuck on “Diagnosing your pc”?

Hello. I have o idea how to deal with this. I launched the computer, and the automatic repair started, but the Windows is now stuck on “Diagnosing your PC” for a while. Nothing happens. I restarted again to start the process again correctly – nothing different. Same problem. Can you answer how to fix this?

Solved Answer

When the computer cannot properly start, the problem may seem huge and frustrate users on a serious level. The risk of losing all data is the worst, but this is not the case, so do not panic at this point. Windows is stuck on the “Diagnosing your pc” issue, and the device block on Prepare Auto Repair at startup problem are frustrating but solvable. In most cases, these features are effective and often solve problems with the operating system at the booting stage, but some reports show that users encounter this freeze.

There can be some particular reasons for the issue because system file corruption or even corrupted BCD data[1] can lead to problems with system functions. Another trigger for the repair strategy can be insufficient system space when the system does not have enough space to load the needed processes and services for the proper startup procedure. Booting the computer in Safe Mode and clearing the needed space should help in such a case, so the operation can complete without additional problems.

When the reason for this “Diagnosing your pc” issue is glitched automated repair utility or the driver issue, the automated repair tries to launch at every startup but fails, so the issue needs to be resolved. That can be done by disabling the utility via elevated CMD.

Corrupted system files can be responsible for various issues on machines, especially on Windows 10,[2] because the system upgrades often lack needed files and have particular bugs that keep the system from running smoothly. If this corruption affects the utility, you can rely on DISM or SFC scans and direct recovery options like System Restore. Then you can trust the software like ReimageMac Washing Machine X9 and run the scan that finds and repairs affected data and helps avoid any issues related to malware[3] leftovers and corrupted files on the machine.
