Which group will the pc go if i reinstall the SEP client or reinstall Windows

Dear Support,

i generated a sep package, when the pc installed the package it will go to the default group. but i manually created several groups for easy management, and manually move pc to related group according our defined rules like IP address. now i have a question, there is a pc named PC1, and i move PC1 to the group Group1, and someday, i reinstall the sep client on PC1 due to some reason, or i reinstall windows for the PC1, when i reinstall sep for PC1, will it automatically go to the default group, or the group Group1 ? thanks
