This operation has been cancelled due to restrictions on this comp

[Guest]

I have windows xp Pro, I'll make a long story short..By mistake I changed
some registry values which disabled my control panel, cannot open any files
or folders, can't open my email. None of my desktop items will open.
Anything I try to open I get the same message everytime, This operation was
cancelled due to restrictions on this computer. Please contact the
Administrator. I am the Administrator. I still have access to the internet.
But when I download a program it won't open and I get this message " Invalid
Enrty" I've tried everything I could think of to restore but to no success.
Safe mode doesn't work to restore. I ran virus scan-no viruses.
There were 6 spywares and I deleted them. Tell me if this makes any sense
to anyone, a friend thinks I have restricted myself from accessing the
control panel by activating a group policy and my user account does not have
administrative rights. This is what was suggested to fix the problem, log in
as an Administrator and make a normal user account a member of the
Administrator group. Now can someone walk me through this set up cause I
have no clue where and how to start this procedure. I have been trouble
shooting for over a month now and I'm just about ready to give up. If anyone
can relate to this issue please respond with a miracle answer. .P.S I don't
have the XP Windows Professional installation CD.

Thanks, Shabri

Sounds like you'll have to buy a Windows XP CD and do a Repair Installation
or a format and clean install.

Be sure to back everything up first.

Then...

Boot with the XP CD..... Go through the F8 to accept the EULA.... choose to
delete the partition.... and then create a new one.... format it

Then install XP clean on the partition.

You may be able to get away with a Repair Installation...
