I wanted to improve the quality of the Internet connection through the bat file commands, it only got worse, how to cancel?

Question

Windows

On the Internet, I found an article in which it was written that these commands

wmic process where name="mqsvc.exe" CALL setpriority "realtime"
netsh int tcp set global autotuning=high
netsh int tcp set global dca=enabled
netsh int ip reset C:\tcplog.txt
netsh int tcp set global netdma=enabled
ipconfig /release
ipconfig /renew
ipconfig /flushdns
netsh int tcp set global rss=enable

can improve the quality of the Wi-Fi connection, after creating a bat file and then using it, the quality of the connection only worsened. How can I undo these settings and return everything to default values?

Answer 1

I don’t know what message queuing (the first line) has to do with it,
but the rest, in theory, can be brought to the default state with two commands:
netsh int tcp reset
netsh int ip reset
I repeat: default for the system. This will not bring the state of the tcp and ip stack to the form it was before the changes were made. To increase the effect, it is better to reboot after that the
set of commands
ipconfig / release
ipconfig / renew
ipconfig / flushdns
is necessary to update the network settings, clear the local DNS cache and should not affect in any way on the quality of your WiFi
PS I hope you will come to the conclusion that without understanding what exactly the commands are doing, running all sorts of batch files from "these Internets of yours" promising to optimize the system is not only stupid but also dangerous

Answer 2

Roll back Windows to a restore point without delving into it.
