You can install Win11 directly via bootable usb drive and use your win10 key to activate it.

Are you using the same hard drive from your old computer in the new one?

Go to the manufacturer website for your motherboard and download the drivers. You’ll need to use another pc and a usb thumb drive.

If its just the screen bezel and the screen itself isn’t damaged, I would glue the crack. Best to use epoxy but super glue will probably be fine. Neither will look pretty but its cracked anyways. Shouldn’t really cause any performance issues or loss of data.

Or you could replace it. The bezel isn’t expensive, and not hard to replace with the right tools, but most people probably wouldn’t try it.

Your work WiFi is probably locked down to block personal vpn services. If by chance its not blocked, you still shouldn’t be using your work laptop for whatever you’re trying to do.
