Hi vw,

Did the past month patches install successfully?


The first step would be to try resetting Windows updates using an automatic script. See:

http://www.yourwindowsguide.com/2015/12/windows...
Make sure you run the script as an administrator.
Please let us know if you need any assistance.

Hello Sumit,

To the best of my knowledge Windows Updates have been working on this computer in the past.

The script reported that it completed successfully.

However after restarting the computer, the update failed as before.

Regards,

VW

Hello Sumit,

I am afraid yes :(

Try doing a repair install. A repair Install keeps everything including Files and applications and reinstalls Windows.

The best and the easiest way is to use first method in the first article.

Hi, Sumit.

I have the same problem.

I tried to follow your guide by resetting windows update using the automatic script you shared through the link above, but the result is still the same.

It says "A current driver on your PC may be better than the driver we're trying to install. We'll keep trying to install."

Since yesterday, my laptop has been completely unresponsive (3 times yesterday and once today) that I have to hard shut down my laptop.

I'm afraid that it will fails my hard drive. I just changed my hard drive 4 months ago because the old one was fried. It's quite expensive and I don't want my new hard drive to be replaced again :(
