Windows 10: system32 on 64bt system contains 32 bit sfc, cmd, dism etc

as far as i know, system32 on 64bit system must contain 64bit versions of files, but mine contain 32 bit versions even after windows reinstall (those type, when big windows.old directory remains after)
so i wasnt able to run, for example sfc /scannow, until the moment i manualy replaced sfc

is it normal? if no, how to automatically fix it? or at least, would it be ok to manually replace all files in system32, that have their versions in WinSxS/amd64* directories?

:)

 

many windows 10 errors

When I ran the sfc it first got to 64% and said "windows resource protection could not start the repair service"

When I ran the DISM it said I couldn't Service a running 64-but operating system with a 32 bit version of DISM

Are there instructions for a 64-bit DISM?

 

Windows 10 File Explorer Opens for a split second and then closes

I'm Getting this when I do the SFC /scannow:

C:\WINDOWS\system32>sfc /scannow

Beginning system scan. This process will take some time.

Beginning verification phase of system scan.

Verification 28% complete.

Windows Resource Protection could not perform the requested operation.

And When running the DISM I get:

The DISM log file can be found at C:\WINDOWS\Logs\DISM\dism.log

C:\WINDOWS\system32>DISM /Online /Cleanup-Image /RestoreHealth

Deployment Image Servicing and Management tool

My Win7 64-bit has the same sfc.exe and DISM files in C:\Windows\System32 and in C:\Windows SysWOW64. The WOW part stands for Windows On Windows. It's an AMD CPU so I also other copies in subFolders of Windows. I usually have no problem running such applets from the Run dialog box.
