possible internet speed increase for windows 10

elevated command prompt
netsh interface tcp show global

looking for
Receive Window Auto-Tuning Level : normal (if normal might be affected by the following)
netsh interface tcp show heuristics
looking for anything restricted

you can turn off autotunning and gain a possible speed increase
netsh int tcp set global autotuninglevel=disabled
netsh int tcp set heuristics disabled
a reboot is required

not tested, but maybe worth a go

Cheers
