<# This script downloads Google Credential Provider for Windows from
https://tools.google.com/dlpage/gcpw/, then installs and configures it.
Windows administrator access is required to use the script.
If Chrome enterprise is not present, it will also download and install it
and it will enroll them to the Chrome Enterprise
#>

<# Specify a -user parameter if you want to bind the current user account to a Google account.
-User [email protected] -> to specify email to enroll current windows account
-MDMvalue 1 -> to enable automatic MDM Enrollment to Google Endpoint Management
-ValidityPeriod 30 -> To change the number of days an account can be used without connecting to Google

Thanks for the script. I'll be using this regularly. Would like to see it install Google Drive for Desktop along with everything else.

Sorry for the late reply. The intend for this script is for Bootstrapping.
Once the device is on Google Management you shall deploy apps directly from there.
I think some parts of this script are no longer needed as Google improved their installation files to cover most of the steps here.

Hi, thanks for the script, I've ran it and bind it to my local account but I'm receiving this message at the login window: "This device isn't yet enrolled with your organization's device management. Sign in with your work account." and require re-authenticate to Google with 2-sv every time.
