Vista / Windows 7 tweaks

These are a common set of Vista and Windows 7 tweaks I apply to machines I use or work on. To use them, you have to run the command prompt as Administrator (right-click on the command prompt in the Start menu to find it). After applying the desired commands, reboot your computer for maximum effect.

Tweaks for enabling advanced networking controls and disabling temporary IPv6 addresses.
netsh interface tcp set global congestion=ctcp
netsh interface tcp set global time=enabled
netsh interface tcp set global chimney=enabled
netsh interface ipv6 set privacy state=disable

An extra command for slow networks, but breaks Battlefield Heroes.

netsh interface tcp set global ecn=enabled

Use these if you're plugged into a network vs a cable/DSL modem directly.

netsh interface ipv6 6to4 set state state=disabled
netsh interface ipv6 isatap set state state=disabled
netsh interface ipv6 set teredo disable
If you have 2GB of RAM or more, use this to bump up your system's file cache.

Also, if you've got $8-15, go find a 2-4GB "Vista-ready" or "Readyboost" flash drive to plug into your box. Format it as FAT32 (or exFAT in Windows 7), name it READYBOOST (not required), and check its properties for a Readyboost tab. If its compatible, you should be able to select up to 4GB of space to use as a cache. This will speed up slow hard drive access.
