Since you paid them already there should be no charge to ask how to repair your OS with no CD/dvds.
"My Windows Media Player stopped working.
I found that there were some files missing."
That's far too vague. If you had supplied an error message that could have helped.
I am running Windows Vista Ultimate.
I upgraded to Ultimate from Home Premium via the internet, therefore I have no disk(s).
My Windows Media Player stopped working.
I found that there were some files missing.
I could not find a way to reinstall these files so I tried to reinstall the WMP, via the MS site.
It said that I could not install the WMP because I already had it on my system.
I tried doing a system recovery from a series of earlier dates but that did not solve the problem.
From here, I tried to delete it but the deleting process (including the registry references) would not remove everything.
I then tried reinstalling each and every WMP but the only one that I was able to put on my system was the WMP Classic (18.104.22.168).
I do not want to reinstall my OS (via the BitLocker) because it wipes out all of my files, and I do not want to have to reinstall all of them (via my CD backups) just to get the WMP back.
So, does anyone know how I can get the Windows Media Player back onto my system?
