This depends on the OS (operating system) that you're using.

For Win95/98/98se/ME, do this:

Click on Start/Run and type in "regedit" (no quotes). Then, click down through HKEY_LOCAL_MACHINE/System/CurrentControlSet/Services/VxD and single click on the MSTCP folder.

If your RWIN is still at Default, then no setting will show here. You will need to create your own in this way:

Click on Edit/New/String Value. Type in "DefaultRcvWindow" (no quotes). Click outside of field once, then double click on new entry and enter the value you choose (decimal). Close the window and reboot your PC for setting to "take."

For 2K/XP, this is the path:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

In 2K, it is called "TcpWindowSize" and is a DWORD instead of a String Value. Create a new one in the same way as above, but choose DWORD instead of String Value. Value may be entered in decimal or hex.

Note: DRTCP will set all of these very easily.
