Windows 10 has a number of features that help optimize its performance on a particular computer. When the operating system encounters an error, it has the ability to provide the user with appropriate resources to resolve the problem or simply fix the problem itself. Sometimes the user is not notified and the problem is bypassed or resolved in the background. One of these functions is the diagnostic car repair function, which runs when the PC starts up. At these times, you will see a message – diagnose your PC or prepare for automatic repair. This feature has proven to be effective, but some users have reported that the repair process is blocked.

Faulty Car Repair Utility – As reported by various users, this problem may also be due to unidentified problems with the system’s hard drive.

One way to avoid this problem is to bypass the auto-repair screen by disabling the utility from the extended CMD window.
Corrupted BCD data – In the most severe cases, this problem can also be caused by corrupted boot data that interfere with the boot process. In this case, you can update all components of the operating system, including the boot data, by performing a clean installation or repair.
