在裝置管理員看到隱藏的硬體裝置

剛剛看到雜誌介紹差不多的東西

不過他提供還有一個方法也可以

執行 -> cmd -> 輸入 set devmgr_show_nonpresent_devices=1 -> 按下enter

C:\devmgmt.msc

開啟裝置管理員,把顯示隱藏裝置的選項打開

你會看到以前插入電腦的所有裝置,清一清,幫機碼減減肥

Issue:
When you want to remove/uninstall a driver, for example, “BitDefender Firewall NDIS Filter Miniport”, you get an error message “Failed to uninstall the device. The device may be required to boot up the computer”. In mandarin, “無法解除安裝裝置。裝置可能是開機必需的裝置。” .
Solution:
1, run “devmgmt.msc” and browse to the device you want to remove/uninstall.
2, right click and pick “properties”, go to “details” tab.
3, read the value assigned to “Device Instance Id”, in my case for example, “ROOT\SW_BDFNDISFMP007″.
4, run “regiedit” and browse to HKLM\SYSTEM\CurrentControlSet\Enum
5, HERE, according to the value in step 4, further browse to HKLM\SYSTEM\CurrentControlSet\Enum\Root\SW_BDFNDISFMP007
6, right click the folder 0007, click “Permissions”, and tick to allow Full Control for everyone. Click Apply and OK.
7, Now, you have the right to remove the folder. Right click the folder 0007 and click “delete”.
8, Go back to Device Manager and you can see the driver had been removed.
That’s it and Good luck.
