Setup MTU in Win XP

How to setup MTU (Maximal transfer unit) in Windows (XP)
Sometimes you need to change MTU on network interface in Windows desktop.

Start program
regedit.exe

Open path
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\]

Choose alias of your interface, e.g.:
[{A892802D-8D6A-4708-A1AA-EA93415D998F}]

Create new key: MTU
Type: REG_DWORD
Value: 195

Note: You can find proper alias by inspecting settings of each interface. Settings of each interface differ at least in Default gateway and IP address.

Note: Default value is 1500 (0x5dc). Values 195 or 190 are useful for erroneous WiFi.
