Hello. A friend of mine have a pc with invalid windows 7 installtion (I get a message that that I may be a victim and so on...).
I have a real original windows 7 pro copy that is still new and wasn't registered yet.

Can I register the bad copy with the key of the good one so it will be legal and she want need to reinstall windows 7 (because then she will need to install all the other programs she already install on it).

I doubt that will be recommended by most here

Unless you can be certain that the bogus installation is from a clean copy with the MS hologram, what came with the disk is suspect. In other words, if it's just a licensing infraction where such as a duplicate of another installation, the better choice is probably to start from scratch with the known legal copy. As well, make sure it's a retail and not OEM copy.

I agree with Steven.

Even if there is No Doubt about the Old Copy I would Do a Clean Install anyway. It just might save you a LOT of Trouble down the Road.

If this other Windows 7 DVD is genuine then try using the key for that on the illegal one. If it works then that's fine.

If not, then you should see a window offering a free toll telephone number to Microsoft to call them to help input the new key. Otherwise a fresh install might be needed and that would mean backing up all the personal files on it.

In reply to: Try it

If it comes back and says its invalid and then a msg that you have 3 days to register - you might as well
do a full install with the new cd ! if they ask you to call - I would bet it will be to tell you how much you
have to pay to use it - W7 has more ' INNER ' workings that encroach on your freedom of what u can
do beyond just the windows. once you register they know everything about your pc - serial numbers of
all the equipment , plus adjustments they make on some of your programs ' so they work better (hahaha) with
w7 ' ... just getting to takeover - ish for my likeing.

You can

You can simply enter in the new product key and activate Windows using that copy, and as far as Microsoft is concerned, that's all it takes.

However, Steven does make a good point that there may be a hidden surprise or two in the pirated copy of Windows that will still be around, so it might be best to simply reinstall everything.
