[Leica] OT: Upgrade Win7-10?

[Peter Klein]

Since there are many fellow computer mavens on the LUG and Olympus 
lists, let me pose this question.  I am still running Windows 7. The 
COVID-19 situation means a I'm stuck at home, which would seemingly make 
it an ideal time to upgrade. But, if something goes wrong, then I'm 
without everything for which I rely on my computer until I can fix it, 
during a time when support or hardware might not be readily available.  
My concerns includes hardware drivers, and software I use all the time 
(Capture One v. 10, music notation software and ham radio software).  I 
have good backups of all my data, but not full backups of my entire setup.

My computer is a Dell Optiplex 980 tower desktop, about 6 years old, 
with 8GB of RAM, two conventional hard drives, a replacement Dell video 
card and a third-party USB 3.0 card. It is not certified for Win10, but 
perusals of the Dell support site have turned up a significant number of 
remarks that  "the upgrade went fine."

I could upgrade, I could wait until the pandemic is over, or I could 
wait until I need a new computer.  I know "official" support for Win7 is 
over. But I suspect that many corporate setups have stayed on Win7 just 
like they stayed on WinXP earlier.  I don't think Microsoft would let 
them all die if some major Win7 malware appeared.  And I run a good 
virus checker (Trend OfficeScan).

Advice welcome.  Thanks.
