Greetings to the forum. :thumbsup:

I had installed Office 2007 in our home desktop to try out (O/S is Windows XP Pro SP2), but it turned out too slowish (our computer is not so new anymore after all), so I had to go with uninstalling it and will revert back to Office XP. Before I do however, and although the uninstall of Office 2007 went successful via Add/Remove Programs, after reading further the related Microsoft KB article, I could notice that some of the registry keys mentioned there were actually still leftover in our registry, so I'm considering removing them, following the documentation in that article.

Before writing further, at once I'd like to stress that I do understand the dangers of modifying the registry, as I do the importance of backing up the registry before making changes to it so that it can be restored if needed. (I have by now exported all individual keys which are leftover, as further I will do an ERUNT backup prior to proceeding with removing any keys.)

For the sake of learning, though, I would nonetheless wish to remove those leftover keys. And I was wishing to do it, rather than by manually deleting them one by one in regedit as it is described in the article, do it by making myself a "regfix" .reg file for that purpose. (Or would you in fact advise best to actually do it manually in regedit?)

From the ones referred in the article, these are the keys which were leftover in our registry, after successfully uninstalling Office 2007 via Add/Remove Programs:

HKEY_CURRENT_USER\Software\Microsoft\Office\12.0

HKEY_CURRENT_USER\Software\Microsoft\Office\Common\UserInfo

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\12.0

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{95120000-00B9-0409-0000-0000000FF1CE}

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UpgradeCodes\000021509B0000000000000000F01FEC

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Products\000021599B0090400000000000F01FEC

HKEY_CLASSES_ROOT\Installer\Features\000021599B0090400000000000F01FEC

HKEY_CLASSES_ROOT\Installer\Products\000021599B0090400000000000F01FEC

HKEY_CLASSES_ROOT\Installer\UpgradeCodes\000021509B0000000000000000F01FEC


Now, my doubt is regarding what "header" to use in the .reg file for the purpose of deleting these specific keys: should it be "Windows Registry Editor Version 5.00" or "REGEDIT4", i.e. should the .reg file be done like this?...

Windows Registry Editor Version 5.00

[-HKEY_CURRENT_USER\Software\Microsoft\Office\12.0]

[-HKEY_CURRENT_USER\Software\Microsoft\Office\Common\UserInfo]

[-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\12.0]

[-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{95120000-00B9-0409-0000-0000000FF1CE}]

[-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UpgradeCodes\000021509B0000000000000000F01FEC]

[-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Products\000021599B0090400000000000F01FEC]

[-HKEY_CLASSES_ROOT\Installer\Features\000021599B0090400000000000F01FEC]

[-HKEY_CLASSES_ROOT\Installer\Products\000021599B0090400000000000F01FEC]

[-HKEY_CLASSES_ROOT\Installer\UpgradeCodes\000021509B0000000000000000F01FEC]


Or like this?...

REGEDIT4

[-HKEY_CURRENT_USER\Software\Microsoft\Office\12.0]

[-HKEY_CURRENT_USER\Software\Microsoft\Office\Common\UserInfo]

[-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\12.0]

[-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{95120000-00B9-0409-0000-0000000FF1CE}]

[-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UpgradeCodes\000021509B0000000000000000F01FEC]

[-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Products\000021599B0090400000000000F01FEC]

[-HKEY_CLASSES_ROOT\Installer\Features\000021599B0090400000000000F01FEC]

[-HKEY_CLASSES_ROOT\Installer\Products\000021599B0090400000000000F01FEC]

[-HKEY_CLASSES_ROOT\Installer\UpgradeCodes\000021509B0000000000000000F01FEC]


Or would that actually be irrelevant for this specific purpose of deleting these specific keys? (I'm only asking just to make sure I won't risk doing anything wrong, also as I've actually been requested to apply some regfixes on some previous times too, namely when dealing with malware removal, and, as Blender was explaining me on one of those occasions, I understand it's important to use the proper header so the registry reads the information properly...)

Thank you in advance for your expert input/guidance. :flowers:


P.S. I had first thought of posting this in the XP forum. But since in the end this isn't really related with the O/S in itself, so I gathered I should maybe best post it here instead?... If I chose wrong, though, please be kind to move my post accordingly. And thank you again.
