I have several laptops which support USB-C charging, and a 65W GaN PD charger. It's nice to have a compact power supply that works on a bunch of different laptops, even if it can't deliver the full power provided by their dedicated chargers -- it's plenty for keeping the battery topped up while doing light web browsing and whatnot.
On some of them, every time I plug in, I get a notification saying "Slow Charger", and that I really should use the packed-in charger instead. I know it's slow, I don't care, but the notification often pops up over something I'm trying to read and doesn't seem to go away on its own.
I don't think I get this warning (or it's not the exact same warning) on every system that supports PD charging. The one that's bugging me now is on a Surface Book 2, if that makes a difference. I just want to change a registry setting or something to stop the warning from appearing, but I haven't been able to find anything about it online. Does anybody know where this warning comes from? Can I kill it permanently?

See the articleHow to Turn On or Off PC Charging Slowly over USB Notification in Windows 10.
The setting is found in the registry at keyHKEY_CURRENT_USER\SOFTWARE\Microsoft\Shell\USB.
The item name is NotifyOnWeakCharger, type DWORD,
and its values are 0 for Off and 1 for On.
The following .reg file will set it to disabled:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Shell\USB]
"NotifyOnWeakCharger"=dword:00000000 2
