Will Repair Install of SP3 with SP2 CD work ?
Posted on 2009-04-12
Can I do a Windows Repair Install of Windows XP Home SP3 with a Windows XP Home SP 2 CD? I do not mean will the repair install start up, I mean will it work as well as Repair Installs work (they do not fix everything).
What I have heard is, for a Repair install you need the same OS version on the CD and the SP level must be the same or higher than what is on the PC's HD. This question violates that rule.
PLEASE NOTE THAT THE RESULT OF A REPAIR INSTALL IS A MIXTURE OF FILES FROM THE CD AND WHAT IS ON THE PC'S HD. My concern is that I will end up with some SP2 and some SP3 files and that will not work.
On the other hand I have read somewhere on the MS website that SP3 is a a rollup of all the SP2 upgrades and a FEW new things. I emphasize the work FEW here. i.e that it is mostly SP2 upgrades. And since a (2004) SP2 CD can be used for a Repair install on a fully upgraded 2009 SP2 PC, then the only problem is the FEW SP3 upgrades so maybe it will fly?
PLEASE REPLY TO THIS QUESTION ONLY IF YOU ACTUALLY KNOW FOR SURE OR VERY CLOSE AND PLEASE STATE WHY YOU KNOW. No theoretical replies please to this EE question.
