I have 2 problems. My desktop gadgets do not work. The few gadgets that came with the system used to work but then it stopped working and shows only a close button. Also lately the gadget manager wouldn't open ans it says "only the system can manage the
desktop gadgets" whereas i'm the only one using the system. I tried to follow your help thread for changing the group policy http://answers.microsoft.com/en-us/windows/forum/windows_7-security/the-system-administrator-has-set-policies-to/71d2a00c-0e87-4fe1-abae-4b44b4dbeef4 but
none of the said methods work since there is no local security policies in my administrative tools, i can't find HKLM\Software\Policies\Microsoft\Windows\Installer
in regedit.
I am the sole admin of my system and I use windows 7 home basic.
1.Have you made any recent changes on the computer?
2.Do you receive similar error message while accessing any other programs on the computer?
3.Do you have any security software installed on the computer?
The steps mentioned in the thread which you have provided is for another issue.
Method 1
I would suggest that you disable and enable the desktop gadgets on the computer and check if it helps.
a)Click the Start button, click Control Panel, click Programs, and then click Turn Windows features on or off.If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
b)Uncheck the box next to
Windows Gadget Platform.
c)You receive a warning message in a pop-up window. Click
Yes.
d)Restart the computer.
e)Repeat the above steps. Now place a check mark next to
Windows Gadget Platform.
f)You receive a warning message in a pop-up window. Click
Yes.
If the above step fails
thenI
would suggest that you
run SFC scan on the computer which would scan for corrupt system files on the computer and replace them.
The
scan may take some time, so be patient. Windows will repair any corrupted or missing files that it finds. If information from the installation CD is needed to repair the problem, you may be prompted to insert your Windows Vista installation disk.

use the System File Checker tool to troubleshoot missing or corrupted system files on Windows Vista or on Windows 7
