Hello Inessa, this is Emily.
If you just want to do a regular system check to make sure there's no corruption or whatnot, I think you can run the sfc scan.
To do so, type cmd in the search on the taskbar and select Run as Administrator to launch it, then run
sfc /scannow
This scan will let you know at the end if corruption is found and if it is repaired successfully. If it is not repaired successfully, you can run additional command such as this:
dism /online /cleanup-image /restorehealth
You do need to make sure computer is connected to the internet when you run the above.
Another command you can consider running is the chkdsk scan, it will look for logical and physical errors on the drive and attempt repair if necessary. This one can take a while and I always recommend starting it before you go to bed as you cannot use the computer at the same time.
Once again, launch command prompt using admin, then run this:
chkdsk C: /r
It will give you a follow up question, type Y and hit enter. It will stage the scan but it won't run until you restart the computer.
