Solve Remote Desktop slow problem on Vista/Windows 7

Here is what you need to do if you have the same issue:

- Run a command prompt (cmd.exe) as an Administrator
- Type: netsh interface tcp set global autotuninglevel=disabled
Disable the autotunning feature in Vista completely, and fit and lock the RWIN receive window to default value 65536 bytes.

If you want to to re-enable it:
- Type: netsh interface tcp set global autotuninglevel=normal

In some cases you may need to use this command in addition to the above, but I didn't have to:
- Type: netsh interface tcp set global rss=disabled

Update! This command makes your network connection EVEN FASTER
Type: netsh interface tcp set global autotuninglevel=highlyrestricted
