after update, why does it freezes? and refuses to install usb drives?

I have not experience the refusal to install usb drive, but when i experienced the freeze was when the update wasn't completed and it fixes after I completed the update. I started using window 10 from the preview build till date, just updated 7 days ago, after a long time to notice some new features like Meet Now and no issues. Another one maybe as a result of the type of computer in question, the ram size, hard drive etc..
