Search for VBoxStartup.log using your hosts search function. It will be in your user space.

I have the same error. I tried to place original uxtheme.dll file to the c:\Program Files\Oracle\VirtualBox\ directory, but error was not fixed. Could you help me, please?

You need to remove the theme hack.

Find the original (unhacked) uxtheme.dll file, as shipped with Windows. Your theme hacker will usually have made a backup of it somewhere. Place a copy of it inside the "C:\Program Files\Oracle\VirtualBox" folder. That should eliminate that particular problem.

I extracted original uxtheme.dll from Windows 7 installer image and copied it inside "C:\Program Files\Oracle\VirtualBox" folder. Could this file be cached somewhere? How can I make sure that uxtheme.dll is signed?

I don't think Windows caches DLLs in the way you mean, but if you are in any doubt then a full rebooting of the host would probably eliminate the question.

Unfortunatelly reboot didn't help me. I've attached original uxtheme.dll file. Could you check it?

I'm afraid not. I consider checking the correctness of Windows DLLs to be slightly beyond my remit. In any case I don't use your version of Windows.

It should be quite straightforward for you to check: look in the VBoxStartup.log - is VirtualBox still complaining about uxtheme.dll?

It is located in the "Logs" subfolder of the VM folder.

Unfortunatelly yes. I see this row on log:
166c.1508: supR3HardenedScreenImage/NtCreateSection: rc=Unknown Status -22900 (0xffffa68c) fImage=1 fProtect=0xf fAccess=0x10 \Device\HarddiskVolume1\Program Files\Oracle\VirtualBox\uxtheme.dll: Not signed.: \Device\HarddiskVolume1\Program Files\Oracle\VirtualBox\uxtheme.dll
166c.1508: supR3HardenedWinVerifyCacheInsert: \Device\HarddiskVolume1\Program Files\Oracle\VirtualBox\uxtheme.dll
Only restoring original file in the "c:\Windows\System32\" folder helped me, but aero themes stoped working :(

Well, the error message shows that the DLL is clearly being loaded from the correct folder, but says it is still unsigned. So, I'm surprised that putting this DLL in a different folder makes it acceptable.

Is it possible to disable uxtheme.dll signing check?
