Dell Latitude E6220 Laptop boot time too long

[CountFoxx]

My Dell Latitude E6220 Laptop takes too long to boot up—3.15 minutes, which I think is too long. I unchecked some and then all the applications from 'Session and Startup, ' but there is no difference in boot time, whatsoever.  I have no third-party software installed.

Any helpful suggestions or remedies, please

First port of call for checking what's going on during the boot time is this post.

As far as I can tell, the Dell Latitude E6220 Laptop dates back to 2011 and will have been expected to run Vista or 7.
Does it perform adequately when booted?
