the application is unable to start correctly 0xc0000005 after windows update

Anonymous

Sorry my english :)

Hello, today, after windows 7 x64 update itself and reboot most of all my applications cant start and crash with error 0xc0000005.

In "installed updates" I see a lot of Security update for Microsoft .Net Framework Client profile installed today, but I cant Uninstall them, click Uninstall, then I see "Setup.exe *32" in the task manager, then receive an error "An error occurred while trying to uninstall <update name>. It may have already been uninstalled" :(

Also I make a system restore, but without any result :(

Any ideas?

How can I manually remove this updates? Registry cleaning or something else?

You have hacked or infected files on your computer.

Check your BCD and do the below fix if necessary (at your own risk)

In Windows open CMD as Administrator and type BCDEdit and enter, if your Windows Boot Loader Path is xOsload.exe then you need to remove some files and repair your BCD.

NOTE: you will need to re-activate Windows afterwards, so make sure you have your Windows 7 key handy.

Boot to Windows Repair - Command

Del D:\Windows\System32\xOsload.exe

Del D:\Windows\System32\xNtKrnl.exe

Del D:\Windows\System32\Drivers\oem-drv64.sys

attrib c:\boot\bcd -h -r -s

ren c:\boot\bcd bcd.old

bootrec /rebuildbcd

Mmmm, I'm skeptical: Let's blame it on a virus? I don't know if the logic holds! If it is a virus the culprit, why don't remove the virus first? In any case, I can't do anything that you, or others, have suggested here, because I'm with my hands tied, as nothing works, but DOS prompt and I.E.! Is there anyone who could suggest an idea to help me out of this nightmare? Thanks a lot in advance: Aldo

Have you tried a system restore after having booted with a windows 7 recovery cd? It will enable you to repair the system from "outside". All explanation & downloads are available here:

http://www.windowsreinstall.com/winre/createfromiso/#.Ug583T3CD1W

If you cannot make the recovery cd in safe mode network enabled, use a third party computer (from friends, family, ...) Afterwards boot your computer from this CD (adjust the BIOS startup order if necessary or hit F10 or F12 while starting the computer) and follow the instructions as given in the link above.

Hope this will help & good luck !

Thank you very much for your courteous suggestions. Actually no:not yet even if this was already what I was thinking to do; but I was just being too little brave, out of concerns of making some mistakes then. I'll now try it out after visiting the link that you indicated me. Then I'll let you know. I'm still wondering, however, why was I affected in a much worse way than anyone else,...

Thanks again: Aldo

The word is KB2859537 causes 0xc0000005 in systems which are either virus-ridden or cracked with a certain tool which copies ntoskrnl.exe as xNtKrnl.exe.

In both cases the file doesn't get updated while the rest of the kernel does, so everything breaks and WOW64 (the stuff which runs 32 bit programs on 64 bit windows) breaks. Only 64 bit apps work.

Solution: uninstall the update, scan for viruses, remove cracks, install the update.

I wonder why SFC doesn't pick that up?
