Some software will detect whether the system is in test mode. Can you hide it??

HyperHide is currently trying to hide test mode use hook in NtQuerySystemInformation (SystemCodeIntegrityInformation).
However, TestMode can be detected easily using the registry:
1)TESTSIGNING in SystemStartOptions
(HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control)
2) Element\16000049 in BCD00000000(1 -> 0)
or use ShellCode in another process (IoGetCurrentProcess problem)

They may also try to load an unsigned driver, or go through the boot driver and verify their certificate.
In any case, you haven't specified which programs will detect it, so it's quite difficult to say which detection it is.
