Installed Windows 7 and ran it with the created admin account from installation to setup the box. Ran my file type editor and it runs fine but when I change an extension, nothing is changed on the system. Next I created a normal user account and ran the program "as admin" and the changes are shown. Am I missing something here?
it sounds as though the first account is not really an admin account
maybe check the permissions/policies for the group it is in ?
Sounds like a virtualization issue:

I know for certain that if you update a data file in the Program File tree, the latest version you worked with may be in a shadow directory. Had to hunt down one such file. This feature started with Vista.
An account with admin privileges will access the file in the main directory, but a user account will need to find the "virtual" directory which is somewhere in the "your account" folder.
I'm sure it makes $ense for Microsoft
