My 64 bit Vista (SP2) system fails the "wanna cry" vulnerability check, so I tried to update it. That's when I discovered I hadn't had a successful MS update since 8/6/2016, KB3168965. Windows Defender update KB915597 failed on 8/17/2016, and there's no update history after that. Control Panel->System and Maintenance->Windows Update->Check for Updates has been spinning its wheels for over an hour now.
I'm reading in <https://support.microsoft.com/en-us/help/949104/how-to-update-the-windows-update-agent-to-the-latest-version> that I need to update the Windows Update agent, but since "Vista support has ended" I can't find a link to that update. I'd like to at least bring this computer up to the last update issued. Is that still possible?
Also, is it possible to upgrade directly from Vista to Windows 10?
I looked at the system requirements for Win 10, and I don't know whether my "NVIDIA GeForce 6150E nForce 430" display adapter qualifies for Win 10. Computer is a quad-core AMD 9150e, 1.8GHz with 4 GB RAM.
I have a Floppy drive on "Standard floppy disk controller" with driver version 6.0.6001.18000, which I need to keep. It's my only interface with an old system running DRDOS that contains records I need to maintain and haven't found a way to convert from Perfect Calc to any current spreadsheet format. Porting via CSV files won't work because I have formulas that depend on data being in the right cells. I mention all this only in anticipation of being advised to just update everything and junk the floppy. My only misgiving about the floppy is that Vista seems to want to cache the whole disk and if it find a bad block I can't get past it.
