i don't know what's wrong, honestly. I booted into safe mode and mine shows the security tab.
don't do anything with what i'm about to share unless someone else says it's ok? alright, because i really don't know if this is what you need, but i've been posting it a few times because it really saved my computer's life once and it works real well as a registry restore. but it's all manual.
Unable to create a System Restore Point!!!
the next QUALIFIED person who views this thread, please give the ok for this, alright?
