Switch often. My "system of choice" is MacOS, but of course many IDEs and EE-like tools don't run on Macs, so I have numerous Windows VMs (one for ARMs, one for PICs, two for AVRs, one for the digilentInc Analog Discovery, and a W8.1 and W10 VM to make sure things still work there.) There's also the linux VM for ESP8266, and various experimental linux variants; Even a W98 VM.
There's also a W7 laptop that gets carted to seminars, and the kids are all using Windows 7 or 8.1 (Each with a desktop and a laptop.)
And an ancient Dell2400 (XP) running the LPKF and the Needham device programmer. (then there are the "basically unused" systems. Some people just shouldn't be given access to eWaste bins. Although I *did* take back all the 386 systems :-))
