Right off the bat, please don't judge too harshly, I'm still relatively new to this forum and not too practiced at formulating my question yet :)

Background:

Because I have to install Windows and do it's configuration on new computers very often, I found some settings are always the same but anyway important (like showing filetyype endings, disable cortana and news & interests, pin Word/Excel to taskbar, etc.)

Problem:

My problem is about the task-view button - I set it hidden in registry (but let the chance to reactivate it anytime). Sure - you can make a change to the taskbar settings manually, but per program this won't work. Because of such changes won't adapt until reboot or restart of "explorer.exe" under normal circumstances:

How can I disable the taskview button (or refresh the taskbar in general) programmatically without killing any process?

And no - other similar questions don't help, since they're related to either the systray or old OS' it's solution are not longer working.

My Environment:

Windows 10 32/64-Bit 21H1 I'm happy with pretty much any solution, no matter the program language.

Thanks in advance for your help.
