What's a back up, precious?

I transfer my images, documents and current browser bookmarks to thumb drives. And that isn't much. I have a 32GB thumb (flash) drive that I've used for years and it is less than a quarter full. I did make a Windows startup thumb drive just in case. It saves nothing but allows me to install a fresh Windows OS but the only thing I use my Windows machine for is gaming. Most of my downloaded games are digitally stored on the Steam, Origin and Amazon sites.
One thing I had to do with my last clean windows install earlier this year was go into the Registry and turn off the wifi. I had to because new Windows install no longer give the user the option of creating a local account. Once the local account is created wifi can be turned back on in settings. I deselect any telemetry settings Windows will let me then use Winaero Tweaker to remove the rest. Microsoft has no idea what I'm doing on my machine or my browser unless I tell specifically them.
Also I never use Norton, McAfee, etc on my Windows computer but then again I'm not browsing the web on it either. In my specific case Defender is more than enough.
Sounds like you and Hombre got a good deal on the HP. What's interesting is nowadays the biggest thing in desktop and "portable" computers are mini computers. They're small but powerful like my Mac Minis. They are typically about 1/8th the size of midsized towers.
Here's a Mac Mini, all other manufacturers of mini computers are roughly the same size.
