A customer's PC is getting very slow after being switched on for some hours.
Seems to be some kind of disk issue....
When going into System Protection, most selections are greyed out and not available (see attached screenshot)
Don't know if this is causing the slowdown, but it doesn't look right.
Have checked (and fixed) the disk for errors (chkdsk).
Uninstalled un-needed applications. User has administrator privileges.
Any suggestions how to get this system protection up and running again?
