Disable SMBv1 without using startup script

Hi,

In our current Group Policy, we have power shell startup script for disabling SBMv1. So this is enabled in our entire organizational OU which I believe will run every time a user logs in. I think this is causing us log on delays and complaints from users.

Kindly suggest any other recommended method to do this permanently via registry or any other setting.

Thanks in advance,

Sanjai
