I have a HP laptop with Windows 10. When it goes to update, it goes for about 20 min and then says it can't update and goes about another 20 minutes to uninstall the incomplete updates. It gives an error code of 0x80070003. I've tried a lot of fixes and then went for this program to fix it, but backed out because they wanted a monthly fee. Can someone tell me how to fix this (in very simple language) or recommend a program that will work for a small fee? Thank you in advance.
