Windows 7: Window 7 Premium vs Windows 7 Professional

Window 7 Premium vs Windows 7 Professional

Since 1997 i have been writing and using the Euphoria Programing Language with first Windows XL and later Windows 7 Premium desktops.

i now have moved to situation where I have no room for a desktop.

So bought a Windows 7 Professional laptop.

A lot of my Euphoria programs don't work. Especially those using the system() and Xcopy commands.

I no longer have access to my desktop.

How can I convert my Windows 7 Professional to Windows 7 Premium?

Windows 7 Ultimate x64 SP1

Some searching lead me to Can I downgrade from Windows 7 Ultimate to Home Premium? - Microsoft Community.

Try at your won risk!

Hello Everyone

I was in a similar situation. I had "Windows 7 Home Prem OA HP" on a HP desktop I bought new and then upgraded the system to Ultimate with an Upgrade key. But now that I bought a refurb desktop with no OS (with a COA for "Windows Vista Business OEMAc") I needed to use that Ultimate license on the "new" refurb desktop. So my "downgrade ultimate to home premium" search brought me here, amongst other places.

I used a registry solution explained here and in several other places, but I made the changes manually and without the use of a popular tool from a website called deviantart. I figured I was better off hacking the puter manually myself. I did however used it this way (notice upper & lower case matching the "Ultimate" entry format):

HKLM\Software\Microsot\Windows NT\CurrentVersion
EditionID "Ultimate" changed to "HomePremium"
ProductName "Windows 7 Ultimate" changed to "Windows 7 HomePremium"

For reference, I also used the following posting on tomshardware (Downgrading Win7 Pro to Home Premium - Downgrade - Windows 7), specially the response by aquasystems. I would've added this reply there but the thread was closed.

Then, I needed to do an "in-place repair upgrade." I tried using the windows 7 repair disk I had originally made with the HP desktop only to realize that it was not what I needed. What I needed was a Windows 7 Home Premium 64-bit installation disk. Since I was afraid to use the system recovery disks of the hp desktop (who knows, it might have worked but I did not want to risk a complete recovery), I downloaded an iso image from digitalriver. For that I followed the advice and links I found here (thanks! Nathan Kim). I burned the iso image to a dvd using imgburn.

To do the "in-place repair upgrade" I used the DVD I had made, popped it into the dvd drive and allowed autorun to start the process (you can navigate to the dvd and double click setup.exe if necessary). I then followed the process as presented by unawave (http://www.***********/installation/...n.html?lang=EN), btw the german screen shot is superfluous. This was a very good step by step site that helped me. I did not get a compatability report about the languages pack; only a small warning that the system needed rebooting before runing setup.exe (which I did before running setup.exe a second time). After the second time running setup.exe, then the rest of the process went as planned. When I was done, I was able to confirm that the windows version had been downgraded to Home Premium.

But, a brief warning about activation of the product key. Once I "downgraded" I needed to re-activate my Home Premium key (stuck on the side of the HP desktop). When I tried activating it, the system responded that it was invalid and that I could not activate it online and needed to do a phone activation process to get an confirmation id. I figured, I was already done with the deed and since I legally owned the license (aka product key) I had nothing to loose. The pop-up warning window asked me to call a toll free number and follow instructions. The call was answered by an automated system which asked me to enter on the phone a total of nine six-digit number groups which were displayed on the pop-up instructions. After this, the automated response indicated that my activation was valid and that I needed to enter eight six-digit number groups (A through H) it would give me to put in their corresponding spaces on the pop-up instructions window (see The automated system allows for all the number groups to be repeated to verify they are entered correctly. I completed the phone verification process and there it was ... the install was activated and fully functioning as it used to be. So, this was a successful "in-place repair upgrade" downgrade from Windows 7 Ultimate to Windows 7 Home Premium (HP original install).

My thanks go to everyone who contributed to this thread. Also, my thanks go to the following websites and postings which also helped me to do this. Mind you, I used the advice in all of them as advice only and did not follow anyone's instructions blindly or uniquely. Always do your homework before undertaking tinkering such as this ... and of course, always backup backup backup since you're responsible for your own actions.

First off. your software not working has nothing to do with running Windows 7 Professional. That has nothing to do with it. Home Premium and Professional and the same exact system. Professional just has some extra bell and whistles that do not affect your software.

As I mentioned in your previous thread. You most likely have a permission issue. If those HDDs (E and F) came from the previous computer, you need to reset the permissions on those drives. Then your software should work.

Just to reinforce what our techie's have stated. The version of Windows is NOT the problem.

To carry it a little further, there is no difference between an OEM version that comes with a new PC and the "retail" versions. Just that the OEM is only legally licensed for the system it was delivered with (or initially installed on).

Windows 7 Pro is not the problem. Where you bought the laptop with Windows Pro installed might be the problem.

I would recommend doing this tutorial by Brink and post here. Lets see if you got what you paid for.

Where did you buy your Laptop?
