You barely have 3 GB RAM available, which is nothing nowadays lol. Even my old laptop from 2009 has 6 GB available.I would get a new PC, but that might not be possible.Windows 7 is OK if you keep it updated and run a PROPER anti-virus. But don't use Windows 7 for too long, cus people are creating viruses for it and Microsoft won't fix the exploits.I wouldn't advice running Windows 10 with those specs, might be running fine or might not. Like Senza and I said, run anti-virus. Take a look at this topic: https://cit.gg/index.php?topic=293248.msg4343876#msg4343876
