If you have installed Windows 7 beta then you must be aware of the bug that whenever UAC is switched off, Sidebar and Gadgets in Vista fails to display properly on Windows 7 Desktop. Though this is not for every machine but many users have reported this problem that their Sidebar and Gadgets are not working properly.
For older beta versions of Windows 7 there had been some temporary workarounds for the same problem. But if you are using Win7 Build 7000.0.081212 then this can be fixed using a simple registry hack which like in Vista will Elevate your Sidebar and Gadgets Process.
If you know how to play with you registry Editor then just open regedit.exe from Run command in Windows 7 and go to KEY
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows \CurrentVersion\Sidebar\Settings
From there edit the DWORD value of AllowElevatedProcess and set it to 1. You don’t need to restart your Windows 7 computer after this. If your sidebar and Gadgets were not working properly earlier then they will be fixed instantly.
For those of you who have no idea what is regedit and Registry Editor in Windows Just download win7-sidebar-fix.zip file and run the .reg file in it inside and when prompted, click Yes to allow.
Earlier if you remember, Microsoft officially released a patch to fix the mp3 sound problems in Windows 7. It seems like Windows 7 needs to fix some critical issues before releasing it fully. On the other hand everybody is impressed by it even during beta stage.
