O.S..
I have updated a Toshiba laptop of mine that had a Toshiba version of XP
Home with an OEM version of XP Pro and it worked just fine. As far as
updating from 98 or ME I don't know because back then I upgraded with a
retail version. I wound up reinstalling XP Pro clean after deciding I didn't
want or need all the junk that Toshiba installs with it's version of XP
Home.The above OEM XP Pro that I installed on the Toshiba was previously
installed on a Sony Vaio laptop that bit the dust. I didn't even need to
call MS to activate. It activated just as a retail version would. I think
the largest difference is the packaging and lack of product support. If you
can do without those, I think the OEM version is a good deal. Of course, you
must purchase a major computer component (supposedly) to get an OEM copy. I
have an OEM version of XP Pro on this system and it is my "test" system
(guinea pig if u will) and have changed virtually everything in it and have
had to make the 10 min call to MS on a few occasions but just telling them I
upgraded, which is true, and they just reactivated normally.
