Solved Unknown program running on startup- CHKDSK

[AJ2001]

Hi all,
I started up my PC just now and before booting up properly, there were messages on-screen about something called CHKDSK running, verifying files. It ran through the wholes system, verifying everything, then said it was deleting some index entries and recovering orphaned files. My knowledge of computers is limited to GCSE Computer Science, so I don't know what any of this means, but the PC then started up as normal. Can anyone inform me as to what was happening? I have attached some photos if it helps.

Welcome to the forum. It's a normal disk check which starts when it thinks there are problems with the drive often caused by a bad shutdown no problems it fixed the errors

Chkdsk is part of windows. It's purpose is to check for and correct errors and corruption in the file structure of your disks. It is automatically run at boot if the system wasn't shut down properly, or if Windows detected errors while it was running and marked them to be corrected at the next boot.


You can manually run chkdsk yourself if you open a Command Prompt as an administrator. Type CHKDSK /? to get it's help page.
