The end of the article misses one possible way to deal with your computer, migrating to Linux. It’s not possible for all the mass of people, but it’s still a possibility.

Your easiest way is to upgrade windows normally and if you dislike all it’s bloated software, just install Atlas OS on top of it. It’s just a software that will go through your windows and debloat it as much as possible. Simple as that. Easier done than reinstalling windows for an LTSC version. I personally have a dual boot with a win 11 with Atlas OS specifically for the software I can’t install on Linux.

No, this is a plugin for KDE.

In the settings, go to windows management, scripts for KWin, then click on get new scripts (don’t know the exact names as my is isn’t English, but you’ll find out). Here you will find in the most downloaded the script KZones.

Install it and you will have a good replacement for the powertoys zones. You just need to edit the layouts to your convenience. For exemple, I have a portat screen so I did a simple layout for putting windows in the upper half and lower half of the screen.

If you are under KDE, there is a plugin for this, but I don’t recall the name. I’ll tell you later when on my computer. I use it everyday.
