re default programs

Hello ruggb, Hopefully I can be of help.

Go into Control Panel>Programs>Default Programs and click "Set your default programs". Select a program and click "Choose defaults for this program". Check or uncheck extensions based on what you would like that program to open.

In addition, in Default Programs, click "Associate a file type or protocol with a program". A list will pop up, and you can select another program to open specific extensions.

Hope this answers your question. Post back and let us know how it goes, or if you need any further help.

Hello Ruggb,

If you install a program on the computer, then by default all users on the computer will be able to run the program unless the program runs elevated and the user is a standard users, or you were able to specify to not allow other users to run the program during installation.

When a users tries to open a file that doesn't have a program associated to open it with, then they will get this below to choose a option to use to find a program to open it with. If they choose the bottom option, it will open the usual Open with dialog.

If you unassociate a file extension (ex: .xls), then that will affect all users on the computer.

What edition of Windows 7 do you have? It depends on what edition you have for what options you may have available to prevent a user from being able to run specific files and/or programs.

Hope this helps some,
Shawn

Apologies for the misinformation. I read a microsoft article that said "default programs" were per-user. Apparently that is limited to setting the actual default programs. Thanks for clarifying.

With certain versions of windows, you can edit the group policy, but I wouldn't know how to do that per-user. Brink will be more helpful here I think.

Hello Dusty,

No, you are corrrect. Default Programs and Open with are a per user setting and not global. It's just that when you unassociate a file extension it strips the registry enty for that file extension which does affect all users. That's all. :)

What about associating another program to an extension (Which extensions to use is another matter), such as wordpad for the "basic" user? I'm not sure what pop-up will be displayed if a program cannot run a specific extension, but it could be helpful, assuming "Associate a file type or protocol with a program" is per user and not global. I have a feeling the pop-up would look much like the one you posted in your first post. Brink, if you are aware of a better method of restricting program access per user, then disregard this post. As you say, Ruggb will likely need a higher version of windows 7 in order to change such settings, if available.

Its a bit controversial, but windows live family safety may come in handy here. At least you would be able to restrict specific programs per user, but a single hotmail account may be needed for that feature, I am not completely sure. Example:

Dusty,

It really just depends on what edition Ruggb has for what options may work best. If the other user is also an administrator instead of a standard user, then none this would matter since the other user will still be able to just as easily change the setting to what they want.

If the other user is a standard user, then one option would be to open the "Security" permissions of the .exe file of any program you do not want a user to be able to run, add that specific user account to the list, and set the access permissions to "Deny" for that user only. This will stop the user from being able to use that program, but not stop them from installing another program that could open the file though.

Permissions - Allow or Deny Users and Groups

Again, we need to know what edition he has to see what may work best. :)
