You actually don’t need to do any modifications to install Windows Defender Final without a validation check.
1) Simply download the MSI file to say C:\
2) Click on “Start” > “Run” and type the following in the run box…
msiexec /i “C:\WindowsDefender.msi” /q
3) Click on “OK”
The software will install silently without the Validation check and without user interaction. It doesn’t ask for validation when you open it for the first time either.
