First DuckDuckGo result for "windows s mode": https://support.microsoft.com/en-us/windows/switching-out-of...

For that, you must know that there is such a thing like "Windows S mode".

As I have mentioned, in another comment, some years ago I had the same problem when replacing an old corporate laptop with a new one, but at that time nobody from the IT support knew about the existence of the "Windows S mode".

At that time, seeing that none of many IT support people could do anything, I assumed that there was some kind of miscommunication inside the IT department, and there was some administrator who had configured some kind of secure Windows mode on my laptop, but the others were not aware about this.

Now I know that the laptop had come like this directly from Dell, but for some reason the IT department did not know about it.

You're responding to a comment talking about hours of tutorial dives and advanced config tweaks, my guy. You really think the official fix isn't the first thing I tried?

That button simply doesn't work. I forget the exact error message, but it was something generic and unhelpful. (Spoiler: none of the other solutions in the first few pages of search results worked, either.)
