Hello. I have a Windows XP Professional system that is FUBAR.

* When I try to launch a shortcut from the desktop, start menu, or control panel, I get the following error:
"WINDOWS CANNOT ACCESS THE SPECIFIED DEVICE, PATH, OR FILE. YOU MAY NOT HAVE THE APPORPRIATE PERMISSIONS TO ACCESS THE ITEM."

* I can not launch regedit, and I get the same error
* I can not install applications, even as Administrator. (I tried installing AdAware 2007).

* I can navigate the hard drive and some things open, some things do not.
* I checked the Sharing & Security tab and set the EVERYONE account to FULL ACCESS
* I checked the Local Security Policy for anything that prevents me from installing applications, but I can't seem to find this setting.
* The computer is "protected" with TrendMicro PC-Cillin 2007 and nothing was detected as far as virus/spyware.

THANKS for any help.
