There is an old post about this topic but it looks like it wasn't resolved. System Reserve is 7% fragmented
My SYSTEM is now 9% fragmented. It has gotten to this level after 1.5 years, but most of it occured in the last six months or so.
I use the built-in Defrag tool and it is set to default. In the old thread OldMX mentions that the tool should defrag the SYSTEM unless a setting was changed, which I don't think I did. And indeed the settings say it should defrag the SYSTEM.
I have not manually tried to defrag that partition. Windows Backup and Restore was mentioned in the post, I do use it but only have the most recent backup saved.
Should I be concerned about the fragrmentation? If so what should I do about it?
