In fact, LTSC / LTSB does not exist in this function, but its emergence makes people helpless, and do not know how to remove, do not know if there is a good way to delete it.
You do not understand what you want and you do not understand whether you're "people" or you talk about yourself. If You don't know, it doesn't mean that people don't know.
As far as i know this context menu entry is impossible to remove - it's hard-coded in some .dll file and if you try to modify that .dll with Hex Editing for example - Windows 10 will not boot.
I can think of one alternative - that is to replace default Open With menu with the Open With dialog directly (but that means no cascading context menu). Better than nothing: OpenWith_direct_context_menu.reg: Code: Windows Registry Editor Version 5.00 ; Open With context menu without Search the Store (AveYo: dialog opens directly so no cascade menu selection) [-HKEY_CLASSES_ROOT\*\shell\openas] [HKEY_CLASSES_ROOT\*\shell\openas] "MUIVerb"="@shell32.dll,-5376" "Icon"="OpenWith.exe,0" [HKEY_CLASSES_ROOT\*\shell\openas\command] @="OpenWith.exe -override \"%1\"" "DelegateExecute"="{e44e9428-bdbc-4987-a099-40dc8fd255e7}" [HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\Explorer] "NoUseStoreOpenWith"=dword:00000001 [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Explorer] "NoUseStoreOpenWith"=dword:00000001 Undo__OpenWith_direct_context_menu.reg: Code: Windows Registry Editor Version 5.00 ; Undo Open With context menu without Search the Store [-HKEY_CLASSES_ROOT\*\shell\openas]
Thank you for your reply. Oddly enough, Microsoft did not pay much attention to such an obvious problem.
