I tried access control panel and I got:
"This operation has been cancelled due to restrictions in effect on this computer. Please contact system admin".
Under my Local Disck (C:) --> Properties --> Security..
All the users:
Authenticated Users, SYSTEM, Administrators, Users lost all the allow permission.
But I am able to login to windows, surf the internet.
Is there any software that can allow me to modify these permission in safemode or other modes?
Hope to hear from someone.
