how tweakUI change explorer right-click "new" menu 1

[olin]

I used to (and enjoy) change registry manually to modify my Windows, but I really stuck on this one. I wanted to change the content in windows explorer right-click context menu -> "new" submenu. I know those items in
HKCU\Software\Mircosoft\WIndows\Currentversion\explorer\discardable\postsetup\shellnew
and also in HKU user image with same directory. But whenever I changed (e.g. remove unwanted values) something in this key, it only works for one cycle. After refreshing the explorer, the old menu templates came back again. I googled but they either suggested to use TweakUI or gave the same precedure as I did. I tried TweakUI, it really worked so I want to know how does it do it.

Anyone has some ideas? Thank you!

p.s. I remember I also tried another trick to disable one CLASS key in HKCR and changed ShellNew key as before, it worked, However whenever I enabled that CLASS again, the old menu was restored again.

solved, by deleting shellnew subkey for class extensions of those programs I don't want in the "new" menu.
