restore default security permissions in windows vista?

[Greer]

Hi, this is Windows Vista system. I am trying to make notepad++ as the default notepad program but due to some permission reasons, i am not able to do the same. I tried changing the settings so that any user listed had full control over my PC. Now I want to change them back & only allow the administrator to have full access. How do I do this please? I have no idea how to do the same. Hope someone here can help me out with this. Thanks.

There is a tool called ICACLS which can help you to easily reset the permission. It is a command-line tool that displays or modifies discretionary access control lists (DACLs) on specified files, and applies stored DACLs to files in specified directories. The following links should provide insightful info regarding the usage of this tool:
