Run SFC directly on Windows
- Save work and open Command Prompt or Windows Terminal as administrator.
- Run the system scan:
sfc /scannow - Leave the window open until verification reaches 100%, then review the result.
- If Windows reports corruption it could not repair, run DISM RestoreHealth, restart, and run SFC again.
Run it on a remote computer
Use only an authorized administrative channel such as PowerShell remoting or a managed support agent. Confirm the target computer before starting because the scan can be lengthy and may require follow-up.
With Screensie Command Center
Open the saved PC, choose Command Center, then Tech → SFC /scannow. Screensie requests confirmation, reports real operation progress, supports cancellation and returns the final output without taking over the remote screen.
Reference: Microsoft: use DISM and SFC to repair Windows.
Run repair tools only on computers you own or are authorized to administer. Back up important data first.
