[Wine] MS Office 2010 installer question

In the howto for Pro + (wine w/o wine-mono support) step two:
Delete all .NET-related registry keys. 

How does one go about doing that ?
$ regedit --> Find --> .NET and go willy nilly on the registry ?  Or look for a folder in HKEY_LOCAL_MACHINE ?  

Sorry if this is something obvious but I have no clue.  Skimmed FAQ/Wiki/etc. but all I saw was how to use regedit but not how to delete all "blank"-related keys

Any help would be greatly appreciated.
