My desktop PC (used primarily for development) has recently been telling me (via Action Center) that it needs to perform "maintenance". I allow it to do so, and hours later (I left it running overnight a couple of times) it is still reporting Maintenance in progress.
Task manager reports no significant CPU or disk usage, and I have separately trimmed/defragmented my disks (a 256GB Samsung SSD and separate 1TB HDD).
Can anyone suggest what might be boing on?
