Clearly Microsoft is worried about the security researchers’ findings, and has issued a “Fix It Tool” which will protect Windows 7 and Vista users by entirely disabling the Windows Sidebar and Gadgets functionality. Microsoft hasn’t issued a security patch to fix the vulnerability.
They’re suggesting you completely nuke your Windows Sidebar and Gadgets.
If you are still having issues with a gadget, you can open up the Gadgets folder that you see above, and you’ll see a list of all user-installed gadgets: You can delete any of these folders if you want (always backup your files first).Tip: The Aero Peek feature (see my Aero Peek Feature Focus) in Windows 7 is designed primarily as a way for users to quickly view, or "peek" at, Windows Gadgets that are hidden by open windows.You can also see gadgets when you use the Show Desktop functionality via the Windows Key D keyboard shortcut.and just because you don’t see the sidebar doesn’t mean it’s not running in the background.First, right-click on the Sidebar icon in the system tray, and then choose Exit.
Which is bad news if you found those sidebar gadgets useful.
