Hi, I recently "upgraded" from Windows 7 to Windows 10 and had to create a User account in Windows 10 on the same machine that I did not in Windows 7. My settings and some plugins registrations are seemingly gone. How can I transfer all of those settings etc to this new account on the same machine? Both accounts are administrator accounts and they are both me (sole user). All info appreciated, thanks!

Hi. I am assuming that you are talking about SONAR, and SONAR plugins. The only things I had to re activate after upgrading to Win 10, was XLN Addictive Drums 2, and Melodyne. This is done on their web sites. IIRC, you will have to remove old pc, and add new.
All the best.
