Yeah the owner (relation, rather than customer) wants a properly licensed version, which is going to be paid for by the voluntary organisation he helps run anyway.
Makes sense to flash the BIOS back to unmodded as the SLIC won't be used anyway. I really don't want to do a clean install though, as I've spent quite a bit of time tweaking and installing apps and would rather avoid having to do all that again.
It should be fine to use the X17-59465 (Win7 SP1_Refresh_Retail_x64).iso I've got to downgrade to Pro shouldn't it?
Wipe and reinstall. Then make a system image of your newly tweaked "properly licensed" system and your family member will love you for it. You can do it any way you choose, but you chose this forum to get its expert advice and members are telling you to reinstall. That alone should tell you something.
Funnily enough I only got the idea of doing a downgrade from mydigitallife
Now if there's a very good reason why this is a bad idea and I should spend lots of my time installing from scratch, then please explain why that is but just telling me a downgrade is a bad idea and I should start from scratch without giving any explanation as to why this might be necessary isn't sufficient for me to spend considerable time doing so.

Thanks, that's very helpful
Actually, my relation's away for a few days, leaving his PC at my mercy
I was thinking maybe I could do the downgrade to Professional and all the Post-SP1 updates, etc now and SLIC activate it (assuming I can find a Pro key), I'm sure that shouldn't be too hard!) and then when he gets his proper key, I can just flash the BIOS to stock and re-activate it with his key then.
Does this sound OK? It's just that it would be good to do as much as possible whilst he doesn't need to use the PC.
That will work.
Check the http://forums.mydigitallife.net/threads/10370-Windows-7-OEM-SLP-Key-Collection thread for the key you need.
Thanks, that's great news and thanks for the link as well, saved me a lot of time searching
Cool, thanks for the tip. Definitely worth taking that small extra step just to be safe
Damn, something not right here.
I modified the registry keys HKLM\Software\Microsoft\Windows NT\CurrentVersion AND in HKLM\Software\Wow6432Node\Microsoft\Windows NT\CurrentVersion to change the Edition ID to Professional and the Product Name to Windows 7 Professional.
I then run setup.exe from the iso mounted in a virtual drive and I get the Edition choice (I removed ei.cfg) and choose Professional but then I just get to choose the partition and it says there's already a Windows folder and it will be renamed to Windows.old but nowhere does it offer an Upgrade option or even mention Upgrade
EDIT: Hmm, maybe something to do with cversion.ini in sources\? http://forums.mydigitallife.net/threads/9416-Expert-Opinions-Needed-Downgrade-Win7-Version
The cversion.ini on the iso is:
and in the registry the currentbuild and currentbuildnumber are 7601 also. That thread suggest the cversion has to be lower than the values in the registry but I don't really understand why it should enable the upgrade option if the registry indicates the current installation is newer than the disc
Nope, tried changing the cversion.ini to 7000 and the registry keys (all four) to 7100 and still no Upgrade option
OK, so you think changing the values in cversion.ini to 7600 rather than 7000 might work (and leave the registry values at 7100 or change them back to 7601)?
I obviously couldn't modify the cversion.ini on the mounted ISO, so I just extracted all the files to a folder on the HDD and modified it there before running setup.exe. I can't see that would cause the upgrade option not to appear though.
OK, I'll revert to the unmodified cversion.ini and change the registry values back to 7601 (after trying 7600).
Do you mean burn the iso to a DVD and try that?
There's "available" updates as I have Windows set to notify but not download or install. The fact that there's updates available wouldn't prevent the upgrade option appearing though would it?
OK, I'll do that then and if it still doesn't work, trying burning the iso to a dvd.
Oh yeah, that was one of the first things I did
That was the first thing you should have done was just burn the iso to make windows 7 dvd.
At the of the day it is always good to have a copy in case you hard drive goes down and you lose archives.
As for mounting it as a virtual drive what would happen if the upgrade needed to reset your computer you virtual drive would probably not be mounted and your upgrade or downgrade would fail because it could not find the needed drive or files.
Why would anyone downgrade from Ultimate to Professional ??? Just wondering
Is Professional better in any way?
I believe the poster said somewhere in the thread that this person's PC was going to go from non-legit Windows to legit. So they evidently want to pay for Pro, not Ultimate.
Oh, I thought Professional was better or something because it had less stuff like no BitLocker
That turned out to be all it was. Once I installed the updates, the next time I ran the Win7 Installer (from the folder on the HDD) the option to "Upgrade" to Professional appeared.
