Hi folks. I am new to this Forum, so bear with me as I get used to it. I have Win XP Home previously installed on my Dell 8200 and I am thinking about buying the XP Pro upgrade package due to advanced features that this OS has. My problem is that my XP Home has some application problems that I can't seem to fix, i.e. my Media Player Licenses have become corrupted and now the Media Player is virtually useless. If I decide to upgrade, will the XP Pro upgrade package overwrite my problem applications so that the upgraded OS will function as if it were pre-installed? Thanks for your help.
