Downgrading Windows 7 Ultimate To Windows 7 Home Premium
Sep 15, 2012
I am doing it because my brother had his computer worked on by our Nephew, and he went from XP to 7 ultimate with a hacked copy of 7 ultimate. I have done a fresh install, but it keeps starting and reverting back to Ultimate, The kicker os that I can go to KEY_LOCAL_MACHINESoftwareMicrosoftWindows NTCurrentVersion and see windows 7 home premium as the operating system with no CD product ID. I'll add the product key, and go to regiser it but it won't let me activate it. The thing I have an issue with is that even after a fresh install, it starts up and says windows 7 ultimate.

I was using a licensed version OS win7 ultimate on my old system. Now after upgrading the system (mobo, processor changed) it prompts me to purchase a new product key. I found that after a major up gradation using the the same product key violates the user end agreement and so I left it there and I purchased a Home premium .( Somebody suggested to convince MS about the up garadation but didn't try it)
Now in the new sys win 7 ultimate sp1 is running and i have to change the product key within 30 days. My query is- Can I downgrade to Home premuim without a clean install?

PC#1 already has Win7 Pro installed on it.I'm building PC#2 and have bought Win7 Home Premium.I want Pro on PC#2, and Home Prem on PC#1. Both OS's are retail box versions, not OEM.I want to downgrade PC#1 from Win7 Pro to Win7 Home Premium without reinstalling. I figure I can change the key on PC#1 to the Home Prem key, so I can use the Pro key on PC#2. Is this as stupid as I think it is? (I won't be offended if you say yes)

I have installed Professional but the key I purchased is a dud. It was a MAC key but when I types it in it turns out it has already been used. I had no luck getting a valid one from the seller.It turns out I only really need Home Premium. If I buy a Home Premium one and authorize with that will it work.The reason I don't want to reinstall is I am using Bootcamp on a Mac Pro and I have to mess around a lot to get it working.

I recently purchased a used computer at a very low price. On it was an installation of Windows 7. All seemed to be fine. I cleared out all the old junk, cookies, registry etc. Now I get a window error saying the computer can not verify my copy of Windows Enterprise and I should check with my IT department. I am a single home user with Windows 7 Home Premium on my other pc. I spoke with a local computer store and they said it sounds like the previous owner put a "bootleg" copy of Windows 7 Enterprise on the hard drive. Can I downgrade the Illegal Enterprise edition to my legitimate copy of Windows 7 Home Premium Upgrade without losing all the programs and stuff I spent the last week installing on the new used pc?

I was wondering whether I could restore the drivers in Windows 7 Ultimate if I backup them from a Home Premium.

In case anyone is running into issues trying to upgrade Windows 7 Home Premium to Ultimate, I did the following things and got it to work. I ran into the "Can't upgrade. Need clean install" issue, and the "you have a later version" issue.
1. Changed the two registry keys in Hkey Local MachineSoftwareMicrosoftWindowsNTCurrentVersion Changed Edition ID to "Enterprise".Product Name to "Windows 7 Enterprise"
2. Browsed the Windows 7 Ultimate CD directory, found the Setup.exe file, right mouse clicked it, selected "properties", and told 7 that I wanted to run this file in Vista Version 2.
Then ran setup from Windows 7 Home Premium.You obviously need an upgrade license for this to work, but I had just purchased one.

If you have installed a preview version of Windows 7 Ultimate (e.g. beta, release candidate build 7100 or RTM build 7600) and want to install a cheaper version of Windows 7 Home Premium or Professional the installation is normally refused.
But with change of a registry key whilst installation you can fake a minor version - so you can install Home Premium or Professional over existing Windows 7 Ultimate.

Why Windows 7 Home Premium ( on my laptop ) is taking up more space than the Ultimate version on my desktop? Both systems are installed, along with the application software, in the C partition of 30 GB with W7HP taking up nearly 4GB more then Ultimate. I have more applications, taking up more space, under Ultimate. Both systems have 2GB RAM, all System Restore points have been deleted, Hibernate is on and I have run both Disk Cleanup (as Administrator) and CCleaner to clear out any junk.

I got windows 7 ultimate 32bit free from my school, and decided that I wanted to clean install, and not upgrade it. I transferred all my files off, booted the laptop up with the windows 7 disk, and proceeded to clean install. I didn't have the drivers cd for my laptop, but I just wiped my drive and installed 7 anyway. Now I have windows 7 ultimate 32bit, and can only use 3 of my 4 gigabytes of memory.. The thing I don't really understand is the whole upgrading option, and like, I know that it's a windows 7 32bit dvd, but it doesn't seem right to go from 64bit to 32bit. So is there anyway I can make it 64bit without having to buy a new dvd? And if not, how much am I missing out on, with not having 64bit, especially with having 4 gigabytes of ram?

I just purchased a PC with Win 7 Home Premium pre-installed. In the meantime, I was able to purchase a copy of Win 7 Ultimate through my campus bookstore for a good price! How do I go about upgrading from Home Premium to Ultimate? Both versions are 64-bit.I do have a physical disk with Win 7 Ultimate. So, please do not direct me to Microsoft's Universal Upgrade Program for Win 7.

i have just upgraded my motherboard, and intend to use the oem licence with that on another build, as per licencehowever, i have a perfectly good install on my ssd of win 7 hp, and as the new motherboard is almost identical (both gigabyte 775 with p35 chipset) and seems happy with the drivers, i was looking forward to avoiding a fresh install,is it possible to "activate" win 7 ultimate (64 bit) and upgrade in place?and will doing so compromise my prior licence (which was a legit upgrade from vista, the vista disks of which have vanished into the depths of time) ?i have successfully done clean installs from the upgrade disk of hp that have been blessed by windows recognising the legitimacy of the oem linked motherboard

my brother's friend installed Windows 7 Ultimate on our computer (illegaly against what I wanted) and 2 days later it keeps saying not genuine. So I went out and bought Home Premium and I am wondering if there is anyway to go from Ultimate to Home premium without losing our programs. If I try to upgrade it says you cannot upgrade form Ultimate to Home premium.
