I'm using Win 7 64 Home Pro, with 8 gigs RAM, a 5450 video card, Gigabyte Mobo. I just reformatted my machine after it became unstable. I've learned from previous reformats and it only took two attempts. After installing about thirty updates things were fine for a day or two. Then it presented me with 166 updates. I let them run but the updates failed. I turned off the auto-update function and am now asking you fine people: do I need these updates? It's an old machine with a new-ish hard drive and I don't want to go to Win 10. According to WU there are 148 "important" updates and 65 optional. I just ran Microsoft's Win Update fixit tool, and I could try again.
