|Thanks, but i've fixed it now!, can't believe how stupid I was!!|
For the benefit of others:
When double clicking the xp_exe_fix.reg file, windows asks what to use to open it. Go to select from list, then browse and find C:\Windows\regedit.exe, select it and click ok, then double click xp_exe_fix.reg again and it'll ask you if you want to add the info to the registry. Click yes and reboot your computer. You should notice that by going Start->my computer->C:\ and opening any one of the folders, all of the programs appear normal again and will function correctly.
If your desktop icons still have the *.lnk extension, run the linkfile_fix.reg by double clicking it, then reboot again. make sure everything seems back to normal and your all done!
the specific locations for the files:
Note: if winzip/winrar or whatever isn't working on your machine, either extract the files on another computer or associate the zip files with the appropriate program exe (winzip/winrar) as done for the xp_exe_fix.reg file.
