Downgrading From Ultimate To Home Premium?
Jan 29, 2012
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?

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 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?

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)

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.

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.

I made the mistake of getting an OEM copy of windows 7, meaning I can only install it to one motherboard, however I plan on building a new system and I was wondering whether or not I should get the full version, just so I can transfer the license to another computer in the future. Also, is it possible to upgrade an OEM version to a full version? like windows 7 x64 home premium OEM --> windows 7 x64 Ultimate full version.

My mother has a relatively new Dell notebook, but she did some rather stupid things with it. Nothing that I can't fix with enough time and effort, but I figure that reinstalling from scratch would yield a better result and probably take less time too. Besides, it's never a bad thing to reinstall Windows every few years anyway in my experience.However, here's the problem: my parents never bothered to order/make recovery disks. I do have a Windows 7 Ultimate upgrade disk laying around though (upgrade disks contain the full OS, right?). However, the laptop itself came with Home Premium and as such, the activation key on it is also for HP.So, can I just pop in the Ultimate disk, yet enter the HP code and end up with a regular HP edition? I vaguely remember that entering an Ulltimate code while installing from a Home Premium disk results in a full fat Ultimate, but does it work the other way round?

So my desktop computer had a nasty virus or something on it, and it was originally a 32-bit Windows 7 Home Premium (as it came with the computer).To get rid of it, I decided to wipe the whole HDD and install a clean Windows 7 Ultimate. But I noticed that the boot time for computer now is MUCH slower now. Before on the Home Premium it would only hang at the "Welcome" screen for only about 5 seconds, then go straight to the desktop and I would be able to use it within minutes. Total boot time: probably under a minute.Now on Ultimate, it hangs on the "Welcome" screen for about 30 seconds, then takes another 10 seconds before I can do anything. Total boot time: 1.5 or 2 minutes.I've tried disabling some of the startup programs and ran a clean boot, but nothign wouthe boot time as fast as it was before. I know that Ultimate has a lot more features, does that explain the extra boot time?

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.
