How to export Registry values for Office 2010 in HKLM.

Question

Hello,
I am trying to export all the Registry keys for Office 2010 in HKLM. All the Office 2010 based registry values in HKLM will be exported and need to be resotred after installing Office 365. So I need to export all the HKLM based Office keys before installing
Office 365 so later it can be restored.
Thanks

Answer 1

Then change the group policy, that's the solution to your problem.  You've made the investment in Office 365 - forcing Office 2010 to launch is wasting that investment.
But what you are proposing won't work anyway, you would need to capture all of the keys and values in 
HKCR\.doc, HKCR\.docx, etc, etc, etc for all of the file types.
Collecting all the registry values, crafting a script to put them all back, and managing that effort is a waste of time when the group policy could be changed in a matter of minutes.  If someone argues against changing the group policy then tell them
to tell the guy who approved the purchase of Office 365 that he wasted the company's money.
If, on the other hand, you don't want users to launch Office 2010 yet, that's another story and I could go on and on debating both sides of the argument.  Instead of spending the time mucking around the registry, try to repair Office 2010 instead:
msiexec /f <product code> /q
you can get the product code from HKLM\Software\Microsoft\Windows\CurrentVersion and just search for microsoft office from there.  The key name it's in will be the same as the product code, which would also appear in the Uninstall registry value.
I hope this post has helped!
