Long story short: after a reboot, something went completely bonkers for 95% of the networking software.
The PC is directly connected to the router by Cat 5. I've had this Vista install working for months.
Vista 32, completely updated, works wonders on this laptop, and so does XP 64 on the PC in question.
The network works, Vista has no problems connecting to the router, I can ping the router & this laptop, I can print over the network (wireless printer), Windows Update works, and a few random apps can get updates from the Internet (Firefox finds updated extensions, but fails to download them).
Most apps, every single game I've tried, and all browsers crash and burn. As long as I'm connected to the network, they crash either right away or upon exit. The event log & sometimes WerFault.exe report software exception 0x0000005 for every single crashing program.
I've tried some fruitless googling, turning of Windows Firewall, diagnose and repair on the network connection reports all dandy, ipconfig /flushdns /renew and /registerdns, rebooting, replugging Cat 5, and undoing the few special things I've been doing for the ~week of uptime: uninstalling a few windows updates, but all the most recent report being installed 10.10.2007 and are inconspicous security & Office updates, and uninstalling the completely new printer.
All I can suspect is some newish hidden or obscure windows update that royally fucked something up. Even safe mode with networking was no go.
I'm really started to run out of options that don't involve one annoying system reinstall.
