Thanks for the command, it worked a treat for us too but we added the /noreboot switch to supress the automatic restart so no surprises for users!

We have updated 2 laptops so far and we have seen
1. The first logon takes a little longer (probably migrating the profile over from the old version).
2. Office 2013 – the first time you launch Word or Excel it runs through a setup step and as you say requires a onetime admin logon. We are looking at hiding this with Group Policy – will let you know if / when we fix this.
3. Microsoft seem to be pushing their own Windows Defender and we found that it was enabled once the update has completed, this doesn’t play well at all with 3rd party security products so you may need to disable Defender from starting up. We did this with Group Policy and changed the following registry key to 3
Change the Type key to 3), I think this was 10 before.
The only other thing we came across and the main reason we delayed upgrading to 1703 is one of our McAfee products was incompatible with Windows 10 (from memory it was DLP 9.3 - Data Loss Prevention) – We have now upgraded to McAfee EndPoint Security 10.5 so all good….
