Well definitely don’t do your web surfing on that partition. Another option could be to run a virtual machine (not dual boot). Might be possible to sandbox that. We did this to maintain support for AutoCad Mechanical desktop legacy files on XP VM on a native Win7 machine after that sw became unsupported. The machine speeds today are much better than they were back then so it might not matter much performance wise. Also you’d suffer some GPU acceleration features but I doubt SWX2004 had much of that and/or it might not matter to you to do rendering. I could be wrong. I suppose one issue with this is you might need to purchase additional software to run the virtual machine which may be what you are trying to avoid. I can’t remember how we accomplished that. Do you have solidworks at work? I just learned there’s a license extension policy where you can use SWX on a home machine for personal use not associated with any work license. Of course, I’d be wary of doing this kind of thing if I were developing any kind of new technology that my current company could claim rights to. (Yeah they are like that). Also SWX is pretty liberal about allowing you to use their software for a year for free if you have a side gig starting up and you’re cash flow strapped. A guy at my work mentioned this to me recently. Not sure what happens after one year, but I guess they’d want you to start paying for it. Of course if you’re just modeling your living room to rearrange your couch and side table, this may not be what you’re looking for.
