Vista black screen and cursor after login

I installed some updates for Vista Enterprise yesterday (the 10th of
October) prior to leaving the office. When I returned this morning
(the 11th), turned my machine on, I got to the Windows login screen,
was able to logon, however, instead of a desktop, I receive a black
screen with a cursor that I can move around.

I've searched the groups, google, etc, the common message seems to be
to press CTRL-ALT-DELETE and close/start explorer.exe. However, when I
press CTRL-ALT-DEL, the only options I'm given is to "Lock This
Computer", "Switch Users", "Logoff" and "Change a password". I can
also shutdown the computer. There is no option for task manager.

I've tried rebooting into Safe Mode with the same result (I see the
Safe mode banner after login, but nothing else). "Last known good
configuration" also yielded the same result (it didn't work). Enabling
Default VGA mode was the same and didn't work as well.

I am now fully locked from my computer and have no idea how to get
back. All this because of some damn Windows update (I was running
Vista fine for a few months prior to this happening).

I have the same issue. I am using Vista Premium and I did the installation
yesterday.

Install USB Cumulative update in KB941600. I had the same issue with
Ultimate and after the third black screen with cursor I BSOD and it pulled
this update. I have had zero problems since.
Yea the exact same thing happened to me. I just scanned my comp and it
found no viruses, however it wouldn't connect to the internet. I was 2
feet from my router and it was on and off. so i shut down the computer
and rebooted. after i logged in, blackness with a curser. Same exact
thing with the CTR ALT DLT. no task manager. This is random. It always
worked before. Does maybe the winlogon.exe have an effect on this?

happened to me before i got everything settled, not a graphics problem
at all, and its not the explorer crash either, not exactly sure, but i
would do a system restore, and memory test from your vista startup cd,
from the cd try a startup repair program, also if u guys have attansic
NIC, that maybe the prob, vista released an update for this which pretty
much crashed your system, to correct this, remove all power, hold your
power button for 30 sec, remove your cmos battery, and boot into
safemode , and uninstall the NIC driver

I am actually having the same issue now with my laptop and Vista. However, when I try to run the new task for explorer.exe, it gives me an error message of, "C:\Windows\explorer.ese is not a valid Win32 applicaiton".

Regarding the issue with the task manager :: if you can manage to get back to a restore point were you can use your computer - you must activate your task manager (as it may have some how been disabled) the easiest way I found to fix this is through the registry. The method i found through google searches I cannot remember, but it offered a download that fixed it for me.

How ironic! That happened to me just two hours ago! The cause of my problem
(and probably your problem too) is that Windows Explorer (the program that
shows the taskbar, folders, icons, Start menu, etc.) had failed to open. Your
best solution is to:

1.) Hit CTRL+ALT+DEL
2.) Select "Start Task Manager"
3.) In "Task Manger", select "File/New Task (Run)"
4.) Type in "explorer" (being "Windows Explorer)
5.) Press ENTER.

Everything including your wallpaper should show up immediately. Let me know
if this helps!

I have the same problem.

Please note from the original post.
CTRL-ALT-DELETE brings you back to the log-on screen with the following
options:
- Lock this computer
- Switch users
- Logoff
- Change a passowrd...

Anyone found a solution to this problem yet?

I have experienced this problem too, and still haven't found a good
solution.

Manually starting explorer.exe using the task manager works for me, but
it's hardly a solution. I don't want to manually boot my computer
everytime I want to read my email, you know :)

So maybe someone can help me out with a permanent solution? Maybe the
explorer.exe somehow got erased from a file with applications to run at
startup? Or is that just silly? :D

OK dudes, here's my fix for my Vista home premium black screen during boot.
After booting up and getting to logon screen and logging on, it goes to a
black screen. I hit alt-ctrl-delete to bring up the task manager option.
When task manager comes up I go to the run option and type explorer.exe and
the computer finishes booting. The permanent fix is going to the registry
and changing this: remove C:\WINDOWS\system32\drivers\ntndis.exe from
KEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows
NT\CurrentVersion\Winlogon\Shell\explorer.exe
C:\WINDOWS\system32\drivers\ntndis.exe

for people that could log in to their accounts but connot see the "start task manager" option during ctrl+alt+del, theres another shortcut for opening task manager...try ctrl+shft+esc...


also have the same problem... im running a dual boot system... both windows vista ultimate...
i cant see my logon screen when logging in my 1st OS (my original OS)...i only see the bootscreen or the progress bar of the bootscreen...right after that, just a black background and a movable cursor...

but when i logon to my 2nd OS (my emergency OS), i can log in succesfully...actually im accessing the internet through this 2nd OS...

i already tried alot of things...
-vista startup repair that came with my vista dvd
-system restore through vista dvd, it did not find any restore points
-safe mode (all types of modes), still the same... same black screen...
-command prompt through vista dvd then performed:
>bootrec /mbr
>bootrec /fixboot
>bootrec /rebuildbcd
-also tried unplugging my 2nd HDD wherein my 2nd OS is installed, but no luck

OBSERVATIONS:
-in my 2nd OS, when i enable UAC then reboot, i cannot access the files on the drive of my original OS...
-but with UAC disabled, i can see all my files and documents of my original OS...
(this proves that it isnt a HDD problem)

if this was a videocard driver problem, how can i uninstall or revert the drivers that i have updated?
i also remember installing acronis true image home and defraggler before all these happened...

i hope someone can help me here...
wishing you a merry christmas!

Hi All,
have been stuck with this for a few days and really it is a very simple
solution, providing you can get explore to run.
Look in the root directory of the "C" drive at a file called "wialog" this
is a text file that records the service that fail to load and most likely
will show you the root cause.
In the recent update there was (for me) an update for the flat bed scanner.
This showed up as failing to load.
Therefore, right click on the "Computer" drive, select properties and then
device manager and unistall the offending hardware.
Windows should now re-boot ok.
Hope this helps, as it did for me.

What happened for me is the following:I had just fixed the notepad opens
everything problem using regedit going in there and deleting the problem
I rebooted once everything was fine I was on the computer for a too long
amount of time watching anime as I am a teenager lol but anyway so then
I am going to sleep and I then I open the windows media open thingy that
records your programs then it says the registry has stopped working so I
restart my computer thinking that it would be fine once it restarts and
I just force my self to sleep when I wake up I login bam black
screen.... I tried opening task manager doesnt work just has the circle
loading and then goes away so if someone can figure this out I would
appreciate it deeply
Thank You

K so i recently had the same problem and like it was big. but in the end
i managed to find out the problem. i used the temporary solution of
simply using CTRL + ALT + Del and then rebooted explorer. after i got it
running i started skimming through my files and programs in attempts to
find a solution. (each time you get this i believe there is a different
solution for everyone.) eventually i found a virus and i thought my
problems were solved. but much to my demise no such luck. but
unfortunately i was having an issue with y True Vector Service a.k.a
ZoneAlarm. it said it could not be started as another program was
preventing it from opening. and i got this notice often. and like it was
my main firewall. well after pondering over the meaning of this i
finally got the smarts to uninstall it. it required a reboot so i did
and it works perfectly now just as before. if any one else is have this
issue and you have zonealarm a message pops up saying zonealarm is
initializing please wait yadda yadda yadda then i suggest you remove
zonealarm and see if it works from there. if this helps please let me
know like i thought i was going to have to format my computer.
