pick up a flash drive i'd say 8 gb is sufficient, use a program like YUMI, which you can download and create a multi boot USB drive, you will have all the tools you need. One of the biggest I use is the offline nt password remover for deleting windows passwords. Become associated with Linux and it's terminal commands. There are also many live AV CD ISO's you can download and put on YUMI that will hunt and kill viruses on windows PCs such as AVG live and Bitdender. Bitdefender is a life saver. It may take a few minutes to load but it's worth it. You'll have to wait after it boots to download all the current updates. I have a kit i bought on amazon, made by ifixit:

I find it laughable that generic toolkits on Amazon come with a chip removal tool... when's the last time you removed and IC chip from a mobo and thought... yeah i'll just get a prom programmer and reprogram this thing? that small toolkit, a laptop for searching for answers, a bible, some holy water, and that stick should get you in and out of most places very quickly, with the exception of ransomware. Ransomware is a bitch, lucky on bleeping computer there have been many many programs developed in order to combat that. The java exploit that locks the screen and demands money can be taken down with bitdefender, but there's also an program developed to remove it. Happy Hunting!
