A critical service failing in Windows 10 can lead to system instability, crashes, and the dreaded Blue Screen of Death (BSOD). This guide outlines a troubleshooting process based on a real-world scenario involving application errors, boot failures, and unsuccessful repair attempts.
After experiencing repeated crashes in a heavily modded game and subsequent errors in Photoshop and Microsoft Word, the system encountered a BSOD and failed startup repairs. The only successful boot option was disabling driver signature enforcement, a temporary workaround that requires repetition with each restart. Furthermore, essential utilities like Device Manager and Windows Defender became inaccessible.
Several troubleshooting steps were undertaken to address the “critical service failed” issue in Windows 10. The first attempt involved running the System File Checker (sfc /scannow). While corrupted files were detected, the utility was unable to repair some of them, indicating a potentially deeper issue.

Next, Windows System Restore was employed, but it also failed to rectify the problem. This failure suggests the issue might predate the available restore points or that the restore process itself encountered an error.
The Deployment Image Servicing and Management (DISM) tool was then utilized with both the /Scanhealth and /Restorehealth options. However, neither command yielded any positive results, further complicating the troubleshooting process. This suggests that the underlying system image might be severely compromised.
A potential link to the page file size was investigated. Initially set to a low value (400MB), increasing it temporarily restored access to Device Manager. However, this fix proved to be short-lived, and Device Manager became inaccessible again. This indicates that while insufficient page file size might contribute to instability, it’s not the root cause of the “critical service failed” error.
While a complete system reset from the boot menu remains an option, concerns remain about whether it’s a worthwhile solution if the root cause is a hardware problem. A hardware malfunction, such as a failing hard drive or faulty RAM, could be responsible for the corrupted system files and persistent errors.
In conclusion, troubleshooting a “critical service failed” error in Windows 10 can be a complex process. When standard repair utilities like SFC, System Restore, and DISM fail, the possibility of a hardware issue should be considered. Further diagnostics, such as memory tests and hard drive checks, may be necessary to pinpoint the root cause before attempting a system reset. If hardware issues are confirmed, replacing the faulty component might be the only effective solution.
