In production environments for security reasons administrators would want to restrict users from changing their account passwords on their own. No matter what client operating system an organization uses or what type of infrastructure is it working on users should always be restricted from changing their passwords at their will. As an administrator you can configure this setting by following the steps given below:
- Logon to the Windows 7 computer with an administrator's account.
- Click on Start button.
- From the start menu right click on Computer and from the menu click on Manage.
- On Computer Management snap-in expand Local Users and Groups tree.
- Click on Users and from the right pane right click on the name of the user for which you want to enable the restriction.
- From the opened menu click on Properties.
- On Properties box make sure that you are on General tab and check User cannot change password checkbox.
- Click on Ok button to accept and confirm your configuration and close Computer Management snap-in.
- Open Command Prompt.
- On the command window type gpupdate /force command to update your current computer configuration with latest settings.
- Close Command Prompt.
If you want to remove this restriction you need to reverse the above mentioned process. (Unchecking User cannot change password checkbox).
