Hi,
I started my pc today, and a messages come up saying,
LogonUI.exe - entry point not found.
The procedure entry point checkelevationAnabled could not be located in the dynamic link library KERNEL32.dll.
I tried safemode but won't start.
Any idea's on what i can do? never seen this message before
Cheers

My first thought, of course, would be a virus problem. When I was looking for that error message, I found things like win32.zbot and win32.Agent.pz mentioned... You can check on those yourself, but I did see part of the description in the link relating to making your system unbootable.

If this happens to be the case, you will probably need some type of bootable anti-virus. I am not that familiar with what is available, but I do know there is something called Windows Defender Offline that can be put on a flash drive for booting.

The first link is a FAQ about it and the second is the download location.

Beyond that, I would try running a System File Check from Offline as explained in the link. After that, perhaps trying a Startup Repair might help.

And it started up? I run @ 4.4 but never had a problem for the 2 weeks it's been clock out.
