Windows 7: Down grading to home premium from professional

@seavixen32 no i didnt clean install i did a system repair method (found through seven forums) and they are still there

@firebird i have read about that method and will try it, but before i do i will create recovery discs from the recovery partition in case they are lost/broken in installation (have read about it happening), so i will do that asap.



btw i did create a system image when i installed professional as instructed to do by a seven forum member, but for some reason i have deleted it, dumb mistake..

Try running Toshiba Factory Recovery now as it may still run if only C was overwritten. Toshiba HDD Recovery Utility

Be aware that you can simply insert a higher-version Product key in Anytime Upgrade to unlock the extra features in minutes.

If Toshiba Recovery does not run, post back a screenshot of your maximized DIsk Management drive map using Snipping Tool in Start Menu. There's a possibility if it still exists the Recovery partition can be made to run by marking it Active then rebooting: Partition - Mark as Active.
Note that you'd use Method Two to mark the current System Reserved (preferred) or 7 partition Active again if necessary. Take note of which is marked Active now.

If this fails, you'll need to order your Recovery Disks from Toshiba Tech Support, or find a Windows 7 retail installation DVD to clean reinstall Home Premium following these steps to get a perfect Reinstall: Reinstalling Windows 7

There is also a workaround to change between versions by changing the Registry key shown below to HOMEPREMIUM for the EditionID and Windows 7 HOMEPREMIUM for the ProductName., then run an in-place Upgrade with the Home Premium installer. Back up your files and set a System Restore point:

thanks i will do the factory reset in two weeks when i can get my Microsoft Office installation disc,
also @gregrocker that last method you mentioned is how i upgraded to professional but i dont think it can be used to go back to an OEM installation.

What do you mean you don`t have the install dvd ?

How then, did you install Pro ?

If you have the dvd you can make a universal ( all versions ) installer.

i have an installer for professional, a .iso atm but have disc back home, can this be used with home premium OEM?

I believe there is a tutorial on how to make it.

thanks,
i think i saw that somewhere, but do you know if it is a clean install or an upgrade/repair as i did before?

Yes you can unlock all versions in any retail installer using eicfg removal tool on the ISO. Explore ISO to make sure it has removed the ei.cfg file from Sources folder, then burn the ISO to DVD using ImgBurn at 4x speed or write to flash stick using Universal USB Installer with Windows 7 in the dropdown menu.

I would not have posted it if it cannot be used to go in either direction upper<>lesser version.

A clean reinstall is alway a superior install and fresh start. Follow these steps to get a perfect clean reinstall: Reinstalling Windows 7

thanks i think i will do a clean install just to get a lot of 'stuff' off of the computer

Do a clean install but DO NOT wipe out your recovery partition. Only delete your C: partition.
