update failures in windows 10

i have an acer aspire E1-531. upgraded to windows 10 first week in aug. from windows 7. first download failed miserably. my son in law removed windows 10 and reset windows 7 to bare bones. then downloaded windows 10 again. all seemed well, upgrade loaded fine. since the middle of august most updates fail. cumulative updates have not installed, period. I keep getting error codes, troubleshooting does no good. says drivers out of date, files corrupted. event viewer is loaded with failures and warnings.
I have Malwarebytes premium. any ideas will be greatly appreciated. do I start all over again? would a rootkit scan perhaps help? is it my laptop? help please.

If you're having that many problems, why go to 10?

What's in 10 that you don't have in 7? 7 is supported until 2020. I haven't seen anything in 10 that's worth the trouble. I've had 10 on 2 test desktops for a year, but will keep 7 on my 2 other desktops and my laptop. Why knock yourself out?

I can't know what is going on with this one.

But as malware is biting so many folk, I'd roll it back to 7 again and see if troubles are there too.

were you having any problems with w7?

Generalized failures like that would indicate your 2.5 year laptop HDD might be failing and causing data corruption. Two test are then called for.

1) Run chkdsk /f /r and on reboot check the Winlogon entry in the Events log.

2) boot to any Linux CD or DVD with memtest in it's boot menu and test the RAM. Alternate is a bootable USB with memtest on it.
