Essential Apps to Install on Windows and macOS

Good article. You got a lot of the big ones.

I would include CherryTree. It's an open source hierarchical note taking application. It is great for organizing your info in a familiar tree-like manner. Lots of customization to how it looks and behaves. There are several programs that do similar, but after trying many, this is "the one".

I did not see a recommendation for non-cloud local full system rotating backup. I am curious what people would like now, either pay, free or open source. Macrium switched to a subscription service last I heard so many left them. But I have not searched for an alt in a few months.
 
Portable Apps is the best piece of software for Windows, it has a massive library of important tools that do not need to be installed, thus can be reused as is over many OS installations.

Kaspersky was and still is the best antivirus.
 
I was amazed at how much I came to rely on Fences from Stardock. Being able to throw together and easily resize (and even hide) infinite desktop windows on the fly got me hooked. No more messy desktop with chaotic icons all over the place.
