Having upgraded 3 laptops and a Gaming Tower, they all take ages from the blue Windows logo to the desktop, up to 1 1/2 minutes. What's it DOING all that time?? Have tried disabling non M'soft Services, no difference...Laptops are all installed with SSHDs so I'm hopeful of an improvement in time... meanwhile think I'll try a clean install using the Product key that is generated by the upgrade.
