Here?s a very interesting one. Unfortunately, I didn?t succeed doing it . Maybe one of the teachies can add his/her touch:If you feel the need to reinstall Windows XP, without any change in your already installed applications, it?s possible.
In Windows XP, go to the folder which contains the installation files of Windows (Which might be a CD-ROM).
Execute the command:
WINNT32 /unattend.
Windows will find the file needing reparation and will do it, while keeping all other installed programs? configurations intact.
