How to back up and restore the registry in Windows
http://support.microsoft.com/kb/322756/
1. Click “Start”, type “regedit” (without quotation marks) in the “Search” bar and press Enter.
Note: If UAC (User Account Control) pops up, please accept it.
2. Right click “Computer” (the root node) in the left pane, click “Export” under the “File” menu, choose “All” under “Export range”, and select “Desktop” in the “Save” in box and type backup in “File Name”. Click “Save”.
Note: The backup file is on the Desktop and named backup.reg. We can simply restore the registry by double-clicking the backup.reg file.
3. Click “Start”, type “regedit” (without quotation marks) in the “Search” bar and press Enter again.
4. Locate the “UpperFilters” value under the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{36FC9E60-C465-11CF-8056-444553540000}
5. On the “Edit” menu, click “Delete”, and then click “OK”.
6. Locate the “LowerFilters” value under the same key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{36FC9E60-C465-11CF-8056-444553540000}
7. On the “Edit” menu, click “Delete”, and then click “OK”.

我沒有試過，畢竟搞錯了會很麻煩。
試過刪除USB3.0驅動再重新安裝，但重開機後，明明刪除的USB3.0又在那邊52。（刪除視窗有勾刪除軟體）
試過用ASUS底板CD重裝驅動都是一樣的。
這問ERROR又不能不理會，因為它會把你滑鼠中間的滑輪搞壞無效，一切外置裝置的USB系統不能被系統識別。
所以上一次乾脆重灌，但重灌又遇上WIN7卡檢查更新，搞了整個星期⋯⋯
所以除了重灌和上面的方法，還有其他方法嗎？
另外，還想知道到底為什麼會發生？是病毒？
如果說是WINDOWS檔案遺失或破損這不可能，我有用sfc/scannow調查過，並沒問題。
