Whenever you attempt to open the User Accounts applet in the Control Panel, the User Accounts dialog pops up, but the page may be empty or filled with raw HTML code. Also, the normal menu options may be missing in the applet.

To resolve the problem, download the VBScript (useraccfix.vbs) file available at the bottom of the page, and save to Desktop. Double-click the file to run it. The script fixes the User Accounts applet automatically.
