系統開機后無響應或黑屏問題的解決方法

最近由于更新系統安全策略,需要run一個vbs腳本，腳本的大致功能是修改組策略，以便符合資安要求，但是腳本運行后重新啟動電腦，發現系統開機以后無法顯示桌面，但是按CTRL+ALT+DEL是可以顯示任務管理器的，大致從網上搜索一篇類似的問題，現把問題描述和解決辦法貼上：

Recently, my Windows Server 2003 box started acting up. I am not sure
if one of the hotfixes downloaded automatically by the server caused
this or a recently installed application is the culprit.

When the server boots, it goes all the way to the CTRL+ALT+DEL window.
After logging in, the Windows Desktop and Taskbar just seem to never
appear. It just sits there. Eventually, after several minutes, the
desktop appears but is generally unresponsive. In Safe Mode, the
desktop appears with no problems.

Resolve Method
For those of you who are interested, I finally resolved this issue. It
apears as some MS patch changed the permissions on the following
registry key:

HKEY_CLASSES_ROOTCLSID

In order to resolve the problem, the following permissions were added

Registry Key: HKEY_CLASSES_ROOTCLSID (and all child keys and values)

Permissions Added:

Authenticated users: Read access
Network Service: full control
