If it's not apparent: you can actually prevent system from accessing the file
by removing access from SYSTEM user to the file.
Windows ACL's are THAT nasty.

[C:\WINDOWS\system32]$ cacls.exe cmd.exe
C:\WINDOWS\system32\cmd.exe DAEMON2\AnrDaemon:R
                            NT AUTHORITY\SYSTEM:R
                            BUILTIN\Administrators:R
                            BUILTIN\Advanced users:R
                            BUILTIN\Users:R

[C:\WINDOWS\system32]$

Ergo, Windows now unable to delete/overwrite cmd.exe... (It's not actually a
cmd.exe - it's a renamed 4nt.exe. Windows SFC always trying to "repair" it.
And always fail. So do windowsupdate.)
