Hi at all,
last days I uninstalled many old applications.
One of them ask me to delete a system file and I answered yes .
I dont remember the name of system file (application was a webcam surveillance?).

Now windows XP start normally like all applications but Microsoft applications make error (live messanger and MSIE).
What can I do to check the name of deleted file and reinstall it without reinstall all Windows XP dile system?

Best regards and thank you very much
Sara
