How to replace SHELL32 without getting c000021a?

[AS95678]

I'm trying to replace SHELL32 with a patched version I made (changes to the watermark) but since SHELL32.dll is a KnownDLL, attempting to replace it offline through Windows PE or Windows RE causes a bugcheck of c000021a (Status: Verification of a KnownDLL failed) Is there a way to replace SHELL32 or other KnownDLLs without causing the bugcheck at boot? This is within Windows 8.1 btw.

I don't know if one actually can do so, but I do know that OldNewExplorer can atleast override UIFILEs within shell32 in memory, thus partially removing the need to modify shell32 directly...

Disable signature checks at boot.

I’ve tried nointegritychecks, ddisable_integrity_checks in loadoptions, and testsigning in BCD but all have failed. Is there something else I have to do in addition to those to disable signature checks?

You may try to sign the file;

When you boot the system, press and hold f10 after bios splash screen.
Then type a space /NO_INTEGRITY_CHECKS and press enter. Give that a try.
