Try:
- Open windows explorer
- double-click c:, right-click perflogs and click properties
- go to the security tab, click advanced,"click continue to attempt the operation with administrative permissions."
- verify that the owner is system
- verify that system and administrators have full control, inherited from none, and they are applied to this folder, subfolders and files
- verify that performance log users have special permissions (or read & execute), inherited from none, and they are applied to this folder, subfolders and files
- if those things are not set that way, try to modify them (you'll probably have to add your current user and give him full permissions)
- after you verified all those things (and removed your current user from permissions), tick the checkbox "replace all child object permission entries from this object", click apply and ok
It seems this fixed the issue on my machine (but I did it right now and I haven't rebooted yet... After reboot it could be broken again).
