Windows 10: Why does last update not finish and causes computer failure?

Last update was very slow and did not finish. Stopped and then screen filled with blue and green squares and has been unusable since. Happened before during an update and I was forced to pay to get tech help to fix. This is very bad and seems like forced obsolescence!!!

After update computer boots to Bios screen

Hi Denise,

Automatic restart after an update may be caused by a hardware failure. As our initial troubleshooting step, we suggest that you follow these steps:

• Press Windows and type "view advanced system settings".
• Select View advanced system settings.
• Under the Startup and Recovery section, click
  Settings.
• Under System Failure, remove the check mark next to
  Automatically restart and click OK.
• Restart your computer.

Get back to us with the status of the issue.

 

Anniversary Update Failure (Solved)


1. Downloaded the Windows Home update.

2. I noticed that it was at 92% of preparing the update, but later found it back at perhaps 5%.

3. Second preparation step finished, gave command to restart the computer and finish the process.

4. First step was to configure the update, which went to 100% in a single step, unlike earlier updates which always restarted the process at around 30%.

5. Computer restarted, and the installation process started working on updating (sorry, I don't recall what the actual text on the screen was.) This was quite slow, with two restarts (as the text indicated would happen.) Around 55% complete, the process speeded up, arriving at around 75% in just a few jumps, rather than percent by percent.

6. Third restart began, which sadly gave an error message that a problem had been encountered.

7 Twice, the process gathered error information and tried to fix whatever had gone wrong.

8. After the second attempt, process went into a restore of previous version of Windows; at least that worked.

This is the first update failure on this machine, dating back to purchasing it last March or thereabouts. Any ideas, suggestions, incantations that I might follow? I don't want to try downloading and going through the same lengthy process again until I have--with luck, of course--anything that might ensure success.

As an aside, I tried twice to download the Anniversary update for my wife's computer; the search for updates stated that the machine was up-to-date, which did not list the Anniversary update.

Having received no replies, I decided to risk trying to install again. This time, the process was much faster than the first attempt; for example, the first stage did not restart, it went directly to 100% and passed matters on to step two. Unfortunately once again the install failed around 72%, but at least it then restored Windows to its previous state.

I was somewhat surprised to find, this morning, that Windows Update does not show that I have a pending update for the Anniversary release. I was further surprised that, when I checked for updates, none were offered. Given that the Anniversary update has not been installed, I wonder why it was not found during the check for updates.

 

method to determine exactly what caused a particular update?

Two suggested articles from Microsoft....

• Fix Windows Update errors
• Troubleshoot problems updating Windows 10

Whether you find the exact cause will determine the level of troubleshooting you go through.
