The same change by hand

You do not need the app for this one. These commands make the changes from the table above. Run them in a Command Prompt opened as administrator, and make a restore point first.

Make the change · CMD
sc config "PNRPsvc" start= disabled
sc config "p2psvc" start= disabled
sc config "p2pimsvc" start= disabled
Put it back · CMD
sc config "PNRPsvc" start= demand
sc config "p2psvc" start= demand
sc config "p2pimsvc" start= demand

How to undo it

In the app: Yes

Switching it off sets a standard Windows value, which may not be exactly how you had it.

Switch the tweak off in Frozen Tweaks. It sets PNRPsvc to Manual, p2psvc to Manual, p2pimsvc to Manual.

Changing several settings at once? The app's Make a restore point button, on every plan, makes a Windows restore point before you start.

Verdict

Safe on Windows 10 and 11. Games do not use these.
