I've installed that script that enables me to take ownership of that folder, but I still can't delete any of the files (I assume the older ones would be OK to delete). What can I do?
If you use method from item 2 of this answer:
- You save last restore point file,
- Another restore points was deleted.
It's preferred for me.
It works for my Windows 10. I don't test in Windows Vista.
Win+R → print
cleanmgr → Enter →
More Options →
All system restore points
except the last restore point
must be deleted.
3. Alternative method
If you want to delete custom file from
System Volume Infomation folder,
Make sure that you know what you are removing.
4. Extra links
- System restore points in Windows 10 (in Russian).
On XP, you can delete old System Restore points via the Disk Cleanup wizard (
Start Menu > All Programs > Accessories > System Tools > Disk Cleanup). On the
More Options tab, clicking the
Clean up... button deletes all but the most recent System Restore point.
I hope Vista provides a more granular control over deleting old points.
