Windows 10 Boots to Black Screen After Running Windows Repair

[Shockwavesix]

Greetings all,

Have a Windows 10 laptop that was having some file permission issues after getting hit with CryptoWall.  The virus has been cleared, but to attempt to correct the file access issues I ran a repair with version 3.8.2 of Windows Repair.

The repair says it completed successfully, and upon reboot I get to the Windows login screen, but upon logging in all I ever get is a black screen with a mouse cursor.

Alt Ctrl Del gets me to the correct menu, but Task Manager won't launch.  Automated Startup Repair finds nothing to fix.  Safe Mode does function. System File Checker is clean. ChkDsk is clean. Running a restore of the Registry from within the Windows Repair program does not fix the issue. There are no System Restore Points to use.

Any ideas?

Do you get Last Known Good Config in Win 10's advanced boot options ?

I had Win 10 briefly but didn't get into it fully because of problems.

Does Event Viewer record anything for the problem ?

I'm seeing alot of "Unable To Start a DCom Server" errors from the time period in question.  Also see a "The Windows logon process has failed to spawn a user application: launchtm.exe"

As for Last Known Good Config, that hasn't been around since Windows 7

Can you boot back into Safe Mode and run all of the repairs in WR again and after the reboot, give it a bit of time to see if it comes back up.

Apparently, Win 10 has been known to do that even after updates.

Good evening,

I fix allot of computers ( about 4-6 a week) and use this tool allot.
I have at least 1-2 computers have this issue a week.
all i do is press ctrl-alt-del and then open task manager. it takes a while.
and then restart.

sometimes that does not always work so i am going to just throw out things i try ..... after a couple of these tries it ALWAYS WORKS... so dont worry.

so if after a restart it still has an issue try.
in task manager on top left click run as adminstrator....and type explorer.exe - this should make everything load up.
i know you said task man is not working for you.... but maybe it will out of the blue ... so if so try this lol

boot into safe mode -- then restart

restart a couple of times in a row like 3 or 4

can you get into services?

if that does not help post what happens step by step when you turn on your computer so i can get a better idea

I have noticed this with Windows 10 as well both in vmware and on my customers machines. My program hasnt been run on these, and even after doing updates or just a random reboot I get the black screen. Sometimes if I leave it for up to an hour it finally goes through, other times I have to restart it into safe mode once and that does the trick or just a normal reboot does it as well.

But after a restart or two it almost always goes through.

The one thing I noticed was that safe mode didnt have the problem. I traced a few of them down to being video driver related, but given how fragile 10 is I am sure there is a ton of different reasons that cause it lol
