Yeah that

Yep, it fails on critical hooks. Some other nasty hook (or anti-virus protection?) affects that. I would like remote access to such machine, dump does not contain all memory.

This version shouldn't crash but won't fully work either

http://startisback.com/StartAllBack_setup.exe

Yes this one doesn't crash but doesn't modify anything as far as I can see.

UPDATE

Oh, I see start actually does work if I push win+shift and it is modifying explorer as well.

I've prepared test version which may work

Ok I think I have found the culprit finally.

I have enabled in gpo

Not loading a non Microsoft binary is "Code Integrity Guard" in MS exploit mitigations. The mitigation for preventing dynamically-generated code is "Arbitrary Code Guard"

This is the error I receive using the fixed version you initially posted. I'll try the standard one and then your latest one next.

Ok, after disabling these mitigations the problem with 3.2.1 persists. I'll try your new test version, thank you!

So far it seems the newer version works perfectly! HOLY GOD

That's nice to hear but I hope you'll find the culprit, write if you have found any more issues, including DebugView log

This new version accurately replaces the taskbar and start menu...

I do get the occasional explorer crash-dump I never had before, after right clicking the taskbar.  the dumps vary, they either points to heap corruption, or to k-lite's thumbs. Crash dump is created and a k-lite popup appears asking to send the dump to their side.

 

Right clicking the taskbar was what triggered the crash. Right clicking the start button never did. But now after a crash, right clicking the start button shows no menu. Left clicking works however. The button appears permanently in the pushed position.

Ok... so i manually forced closed explorer, reloaded it to test more. This time I got the Icaros popup without explorer crashing. Right clicking about a dozen times eventually caused the right click menu on the start button to stick & stop working. The rest works fine however. No crash/dump  yet on this try.

Ok to recreate without fail, I right click the start button, and then immediately right click the taskbar, or visa versa... then click anywhere else, and it crashes. I'm using the latest k-lite standard version

https://www.codecguide.com/download_k-lite_codec_pack_standard.htm

If I disable k-lite thumbnails, or uninstall k-lite codecs the crash on right click problem persists.

looks like all the previous bugs have all been fixed in 3.2.2, zero problems so far! Great work! Masterful work! Thank you.

Is there any use for you to connect to my computer and perform debugging at this point?
