There is a new born in our studio called Windows 7. So the build went well and we have our video editing applications installed. The only issue we found so we far is the remote desktop connection was slow. I mean very slow.

We have a solution for those who encounter the same issue.

The issues was caused by the Windows Auto-Tuning. Click the link if you feel like reading all of the technical background.

The fix:
– 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

Or
Type: netsh interface tcp set global autotuninglevel=highlyrestricted

————-

you can set the values via the registry
