Some of these are easy and some are cheap, others, less so. All valid things to check when you have complaints about computers or internet being slow. My perspective for businesses is that holding onto a cheap slow PC isn't saving you money, it's costing you thousands is lost productivity!

Laptops and phones walk, audit access, encrypt hard drives and enable remote wipe centrally on all devices.
