Resetting Permissions

[Adam]

I recently dabbled in the security options an file sharing
option (right clicking on the drive, security options)
after I had a scare that someone might have hacked my
system

Is it normal to have an "Everyone" user? When I tried to
remove it, I was completely locked out of my computer, so
I had to restore it. Since then when I log on as
Administrator, my system tells me it can load the user
environment and instead will load the default one.

I can't install programs, I get error messages, out of the
4 I tried to install, 3 failed.
Errors 1607 (Run time) & 1603

I searched through the knowledge base to find info on
resetting but there is really nothing there, How do I
restore the "default" permissions and get back the power
to install programs?

Run:
cacls c:\*.* /T /E /C /P Everyone:F <enter>
from the console window in safe mode.
So long as cacls is available there ;-)

/T Changes ACLs of specified files in the current
directory and all subdirectories
/E Edit ACL instead of replacing it
/C Continue on access denied errors
/P Replace specified user's access rights
(F == full control)
