Recently I was having a problem getting some software installed on my laptop running Windows 7.
The software (IBM’s Rational Developer for Power Systems) has a custom installer. When I tried to run the installer, it was complaining about some internal version number. Problem was, I couldn’t find any trace of the installer or it’s data.
On a Windows XP system, the installer’s data would be in the “C:\Documents and Settings\All Users\Application Data” directory. When I tried to find the “All Users” home directory in Windows 7, I couldn’t find it.
User home directories, on Windows 7, were moved to “C:\Users” … but using the file explorer, I couldn’t find the “All Users” sub-directory. I did, however, find the “Public” users home directory. This directory didn’t have an “AppData” sub-directory.
After a little experimenting, I found that if you configured Explorer to not “Hide Protected Operating System Files”, the “All Users” home directory showed up.
Turns out you can also type “C:\Users\All Users” in the address bar to navigate to the appropriate directory.
I find it kind of odd that that particular home directory is hidden, even from administrators, when critical data could be stored there.
