You laugh but the fact that you got a login confirmation notification means he got your password now. He'll just need to guess your email password next and you'll be truly owned. Set up 2fa on your email account if you haven't set it up already.
There actually are updates to it as for the last three years Microsoft has continued to patch it under the commercial "Extended Security Update" program - that only ended in January 2023.
You just couldn't get them as a home user without doing a lot of tweaking on your own.
You know how when you press the Windows key and are able to type into the searchbar? Prior to 10, this bar did an instant local-only search of your desktop applications and (if you enabled it) select cached documents. Imagine building up the muscle memory of using this to launch applications for a decade or two to the point where you don't even look at the screen anymore when launching apps. Now imagine that Windows 10 comes along and introduces a mandatory internet search that has to complete before it lets you see the local results that you were actually looking for.
Now imagine not being able to forget how snappy it used to be every single time you launch an application. Imagine the annoyance of being punished for a typo by having Edge open up a Bing search instead of the application you were trying to launch. Imagine not noticing the error and waiting 5 seconds for Bing to boot up, only to be confusedly greeted by a search you didn't ask for in a browser you wish you could uninstall. Imagine installing third-party applications to try and restore the old search experience only for it to get regularly broken by OS updates you cannot opt out of and are only sometimes notified of in advance (another "feature" that Windows 10 brought).
IMO Windows 7 was the last "pure" Windows before the power balance at Microsoft tipped in favor of the cloud & sales people.
I'm using a Win7 machine at work, because I have to support a system that saw it's last update in 2014. There is actually a Win10 compatible version of this software, but it only supports maybe a third of the chips of the original software, and sadly the ones we use are not among those.
And it can get worse. I've got an oscilloscope that "runs" under a heavily modified version of Win98...
Assuming it is not on the network, I don't care what OS it runs. I'd like to see if I could run your OS on a virtual machine and give access to the hardware.
Does your scope give good resolution? How does it compare?
The scope is an old 4-Channel digital scope from HP (now Agilent). It cost about a fortune when it was bought, and now I got my hands on it for a (small) donation in the barbeque fund. It needs some work (some dials' contacts need rework, and it definitly needs a new fan that does not sound like a starting plane. But otherwise, it is still good.
It only was retired because for our next project, 2GS won't cut it. And the amount of samples it could store was not much (for our needs), too. Still overkill for my private projects, with the bonus that I don't need to dig through manuals, as I know this thing inside out.
Reminds me of a recording studio I used to work at which had an MS-DOS machine long after Windows XP came out because it was what we printed cassette labels on. With a dot matrix printer.
Because she is 9 and doesn't know how to do much of anything with a computer. So to ensure she doesn't break anything or end up where she shouldn't.... Windows vista
