So far, I have discovered the following:
I cannot do a search for files and folders on my computer. The module is missing (something about Search Companion cannot be found... rerun installation).
System Restore does not work. A module is missing. It won't even let me disable/enable it to clear the memory.
When I try to do a Windows Update, I get a blank page and it won't update.
Also my MSN Explorer Butterfly Browser stopped working so I uninstalled and deleted that program. I redownloaded it and tried to install it again and nothing happens when I click the installer.
I truly think my XP is corrupted. I have to wait for the cd to come to do anything about it, though.
Thanks for your help.
