Error message: winlogon.exe – Entry Point not found

When I start my machine, as Win 7 64-bit is just starting, I get an error message:

winlogon.exe – Entry Point not found
The procedure entry point InterlockedExchange could not be located in the dynamic link library
kernel32.

I hit return and as the Windows flag is just appearing, another message:

userinit.exe- Entry Point not found
The procedure entry point InterlockedExchange could not be located in the dynamic link library
kernel32.

I hit return and Win 7 starts as usual.

I don’t use this machine and it isn’t restarted very often, so I have no idea when the problem started or what might have caused it.

There were no usable restore points.
System repair from original DVD didn’t find a problem.
System File Checker didn’t find anything with kernel32.
Regsvr32 gave the following message:

30465-ScreenShot002

DllSuite (commercial dll repair software) found nothing with kernel32.dll and could not help. ReimagePlus–same story

Does anyone have any suggestions?
Thank you.

Hi,

Welcome to the Lounge.

I would think kernell32.dll got corrupted, somehow. So I would do two things:

1. Run an antimalware app to make sure you don’t have some malware creating issues. Malwarebytes antimalware and SuperAntiSpyware would be recommended for that. What antivirus are you running?

2. Try running sfc /scannow in a command prompt window and see what results from that.

If a solution doesn’t come from either or both previous steps, probably a repair install would be in order.

Thanks. I’ve tried both with no success.

Also, Run MalwareBytes.

Are you familiar with the Windows 7 repair install procedure? Have a look to see how comfortable you’d feel doing and go for it, if the issue is important enough for you.
