PowerShell: After ADMT Password Migration Fix

If you used Microsoft's Active Directory Migration Tool (ADMT) for any major migrations, then you know that migrated AD accounts are always set for user must change password upon next login. Well in the target domain we didn't want this setting set due to were migrating the password from the old domain and had complexity filter set so ADMT logs would tell us which accounts didn't meet the password criteria.

Below is the PowerShell code that met our after ADMT user migration fix needs. I used a switch statement on UAC so that account enabled status remained the same. Be advised that this code will set the user account so that user cannot change their password.
