Please repost how to upgrade XP and Win 7 RC, unless you are referring to a clean install (what MS calls a “Custom” install). I have done “clean installs” on two machines, and have a few more to do. It will be a lot easier if I can do an “in place” upgrade.
For upgrading XP to Windows 7...
Here's the link to Laplink, which will migrate your XP to Win7, files, installed apps, and settings...everything.
Available by download here for $ 19.95 (Limited Time Pricing).
Remember, if you have a legal copy of XP, you can buy an Windows 7 Upgrade at a reduced price from the full version.
BTW, you do know that you can do a straight upgrade XP to Vista, and then upgrade Vista to Win 7 also, don't you?
I have the instructions to upgrade the beta or RC to OEM somewhere. I think I might have left the file on another pc, so, I'll have to find them again.
