To add a .reg file silently to your Windows registry, you can use the regedit command. As almost always, the /s parameter is for silent and /q for quiet.
regedit /s your-key.reg
In this post, you learned how to silently import a .reg file into your Windows Registry. This neat regedit.exe trick comes in handy quite often. The regedit.exe command is valid for Windows 11, 10, Windows Server 2022, 2019 and older.
It’s not entirely silent, as it asks for administrator approval. I want to use this in a login script for computers that are not joined to the domain.
It used to be silent but suddenly, as of the last couple of weeks (SEPT2020) its now triggering UAC on Windows 10.
For Windows 8+ you can use REG IMPORT instead
So, previously, and for many years:
regedit /s “registry-to-import.reg”
now
reg import “registry-to-import.reg”
