I was doing a Disk Clean up and I accidently deleted my Microsoft Paint ( which I use alot ), I was wondering how I can get it back? If I reinstall Windows will I get it? Also, if I do reinstall would I have to enter the CD key again? Because the Windows copy I have came with a used CD key and I had to call Microsoft for them to give me a new one. Or can I just redownload it through the MS® website?
