Taking (back) ownership from Vista

It started with what was supposed to be a simple update to Thunderbird on my Vista system. I'm just starting to learn about Google sites, and I was unable to edit anything with my current version of Firefox.While I was updating, I thought I'd check for updates to Thunderbird, and sure enough, there was a new version. No problem, I thought, download, install, and back to work. But no, the install kept stopping at writing to a file called mozMapi32.dll, and no matter how many different permission buttons I clicked, it wasn't going to budge. Nor could I manually delete or rename the file, even as an Administrator*. By now I was going to get that Thunderbird update installed one way or another, so I googled around for deleting files on Vista, and found this promising post: Add “Take Ownership” Option to the Windows Vista Context Menu. What a relief! After installing this little fix, all I had to do was Shift-right-click the offending file and select "Take ownership". I renamed the file instead of deleting it, just to be on the safe side, restarted the Thunderbird update, and now I'm back in business. Thanks to Santosh for pointing this out!

*By the way, I log on to Vista as an Administrator every day; it's my only account. Some may liken this to driving without a safety belt, but my response is that if I'm forced to take something off every time I want to signal a lane change or put on the brakes, it hardly has anything to do with safety, does it? And yes, I buckle up before starting the car, and I clip on before going up on deck. And I back up to two separate external hard drives, automatically, every day.
