I accidentally deleted registry keys under hkey_current_user>software>classes. The classes folder got completely deleted. The moment I did that system stopped functioning properly.

And, since then system doesn't boot up to login screen. A black screen with pointer appears. I tried system repair but it din't work. I could transfer files from C Drive to external Drive.

In safe mode it loads drivers list but gets "Stuck" on aswrvrt.sys where it stays for 20-30 seconds. It then shows the "Starting Windows" screen for 20-30 seconds then all I see on the black screen is the mouse cursor.

I can see the Registry editor using cmd.exe. Is there a way I can restore previous registries or copy files externally?
