If you have a company computer the Group Policy may not allow you to edit or add new Scheduled Tasks. Luckily, you can override those settings until the Group Policy is refreshed. Below is what needs to be changed in the Windows Registry to allow you to edit or add the Scheduled Tasks (under Start Menu | Control Panels).
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Task Scheduler5.0] "Disable Advanced"=dword:00000000 "Property Pages"=dword:00000000 "Execution"=dword:00000000 "Allow Browse"=dword:00000000 "DragAndDrop"=dword:00000000 "Task Creation"=dword:00000000 "Task Deletion"=dword:00000000
[HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\Task Scheduler5.0] "Allow Browse"=dword:00000000
To create a double-clickable file just open up your favorite text editor such as NotePad++ or NotePad. Paste the contents above into your text editor, and save it in a file of any name, as long as the extension is .reg.
Double-click the file to merge the settings into the registry. You should now be able to add or edit your scheduled tasks.
