Recently I bought a Sony Vaio laptop that runs Microsoft Windows Vista. When I try to open the Vista sidebar I get an error window saying that “Windows Sidebar is managed by your system administrator”. Even when I tried to run the sidebar.exe (that launches the sidebar) as administrator, I was still getting the same error message. Googling around, I found the fix, which is very simple and requires basic skills of registry editing.
- Click Start, type regedit.exe in the search field and press ENTER
- Navigate to the following path:
HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Policies \ Windows \ Sidebar
- In the right-pane, delete the value named TurnOffSidebar
- Repeat the same in the following path (if there is a sidebar value there):
HKEY_CURRENT_USER \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Policies \ Windows \ Sidebar
- Exit Registry Editor
Finally Windows Vista sidebar is up and running as it should from the very beginning!
