Photoshop 6.0.01 not working after Windows 10 update

Ok, I know, I'm old! I am still using PS6 ! I have it on my laptop and it does everything I need, so why pay for  a newer version?

So my problem is that after doing the latest Windows 10 update this week, I was getting an error that would not allow Photoshop to open, it would start to open and then just stop and give an error. I did some searching and found people saying to reset the preferences to open in a previous version so I tried this, but it didn't work. I was only able to get it back by uninstalling the Windows update and Photoshop is now working. 

The problem now is, I keep getting a pop up from Windows telling me to install the update every half an hour or so. So what are my options? Obviously I will eventually have to install the Windows update, but then I am left with no Photoshop. It looks like my only Photoshop option now is a monthly subscription at $30 a month? I don't want to do this as I only do a few photos a month , so it's just not worth it. I saw that there is a free to use basic version that I can download to use with Windows ( Express?), but it only does the bare minimum and doesn't for example, resize photos, which I use on all my photos,  for a small website that I have.

What I use Photoshop for is, resizing and cropping photos, rotating and contrast/brightness, some touch ups such as clone stamp, blur tool, paintbrush and sometimes using layers. Nothing fancy.

So I guess my question is, is there a work around to fix my problem that I haven't tried yet or is my version just too old so it's now good for nothing? And if it is too old, what should I use now?

I would appreciate any suggestions for something that isn't a subscription and that is not complicated to use. I am worried that my basice knowledge will not be enough if I get the latest version and I will be paying for things that I don't need or even know how to use. Any ideas?

Thanks so much.
