As most have found out if you disable the UAC (User Account Controls) the desk top gadgets don't work. I found the registy edit that lets you disable UAC and keep the desktop gadgets. I did reboot to see if it works and it does!
using Registry Editor
1. Open Registry Editor (regedit.exe)
2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Sidebar\Settings
3. Create a new DWORD Value called AllowElevatedProcess
4. Set the value of the new DWORD to 1
5. Close the registry editor. Your gadgets should work now. No reboot or anything necessary.
using Command Line
C:\Windows\System32\cmd.exe /k %windir%\System32\reg.exe ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v EnableLUA /t REG_DWORD /d 0 /f
