I upgraded windows 7.0 on my Dell XPSL501X to windows10.0

I got a new Cannon Cloud Printer and don't need the many HP programs (in Control Panel-Programs & Features) as I dont have it linked to an HP printer any longer.

I tried several times to uninstall the HP applications and cant. The first time the computer seemed like it was progressing but after 10 minutes I had to shut the power off. It was stuck in the process, and unresponsive. The other times it would say click finish to restart/uninstall, but nothing would change after the reboot. All HP programs and applications still in in Control Panel-Programs & Features.
