Thank you for allowing me to join the forum. I have been using the adw cleaner for a couple of years after a recommendation from a Minecraft game Facebook page. We have one Win7 machine that could not be updated because of something I downloaded. I spent hundreds of dollars to let a student install a new hard drive and attempt to speed up a painfully slow machine. Nothing was gained, and my kids need it for school. We have one Win10 machine that I messed up as well. Also needed for school.
My oldest son is interested in computers, so I am hoping he can learn to repair and maintain our current machines. He is taking a programming class this year.
