Windows 7 (black screen with a cursor)

I tried
REG ADD
HKEY_CURRENT_USER/Software/Microsoft/Windows/Current/Version/Policies/System /v NoControlPanel /t reg_dword /d 0
and REG ADD HKEY_CURRENT_USER/Software/Microsoft/Windows/Current/Version/policies/Explorer

still not working

Reinstall Windows and start again perhaps? You've tinkered too much with the system.

If it just reinstall windows why i need to asking you?

hi i had the same thing and tryed this methode wich worked

Correct the ACL permissions of the following key to the default permissions:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

rewrite a REG_SZ string called Shell and set it to explorer.exe. even if its allready explorer.exe .

and here is a video explaining how to do that : https://www.youtube.com/watch?v=VUGLXNX0hlA
good luck

Sorry , I cant login windows without "System Recovery Options" (All of safe mode etc are black screen) .
So, the "System Recovery Options" are "X" drive : "X:\Windows\regedit.exe" I can using this one but not C/D drive . If i use regedit.exe from C/D drive it will not open.I can just use the X drive regedit.exe
If i make any change from "X:\Windows\regedit.exe" it just change X but not C or D , so.. not working at all.

I'm trying to use CMD "REG ADD" to update the Shell data to Explorer.exe , but i don't know the code. Still trying ...

I think the CMD "REF /?" ALL kind of change is just change for "X" but not C or D it is not useful .

hi, just a question : if you insert a usb key does it load ?? if yes download windows "process manager " it works the same as taskmanager and run it from the usb key . here it is the link Process Explorer

Sorry , it is black screen with a cursor .
I think the black screen is not logged in my account.

before the black screen with a cursor , the screen gone dark and go back to black screen cursor.
I used color to explain this effect:
After Loading Windows7 Logo , The color in the screen is XXX and just 1,2second later , it was XXX and turn back to XXX and this screen with a cursor.
