After the latest WU, my laptop would not automatically restart - "Active Hours" problem - Windows 10

At 23.55 last night, Cumulative WU KB4551762 finished downloading but didn't install. The message gave me the choice to either "Restart now" or "wait until my active hours". But my active hours are 08:00 - 01:00 so it should have restarted.

Is there any action that I should take?

PS In case it's relevant, I subscribed to receive Microsoft Security Advisory Notifications but I didn't get one for this update.

Hi Taffy. I'm Greg, an installation specialist, 10 years Windows MVP, and Volunteer Moderator here to help you.

Go ahead and restart the PC, then check if it installed in Settings > Update & Security > Windows Update > Update History.

If not manually Update from here:

If these all don't work then I'll give you everything possible in order of what's worked best helping to fix the Store a dozen times a day for years. Even if you've tried a step please do it over in this sequence. If any steps cannot be performed then move on to the next. One of these will always fix it:

1) Try updating Store apps:

2) Make sure you have the latest Windows 10 version 1909 in Settings > System > About and if not skip to Step 10 to install it by the most stable method which will always solve Store problems.

3) See if the fixes here help:

4) Try running the Windows Store apps Troubleshooter in Windows Settings > Update & Security > Troubleshoot.

5) Try resetting the Store cache:

6) If that fails to fix the problem go to Windows Settings > Apps > Apps & Features to highlight Microsoft Store, choose Advanced Options, then Reset. After it resets, restart PC.

7) If that fails then reinstall Store. Type CMD in Start Search, choose Command Prompt result to Run as Administrator, copy the following code and paste it into the box using the Edit tools from Box's top left dropdown menu, press Enter:

PowerShell -ExecutionPolicy Unrestricted -Command "& {$manifest = (Get-AppxPackage *WindowsStore*).InstallLocation + '\AppxManifest.xml' ; Add-AppxPackage -DisableDevelopmentMode -Register $manifest}"

8) Clear the LocalCache Folder: Open Run by pressing the Windows key + R hotkey.
Copy and paste %localappdata% in Run and click OK.
Open Packages> Microsoft.WindowsStore_8wekyb3d8bbwe > LocalCache folder.
Press the Ctrl + A hotkey to select all content within the LocalCache folder.
Press the Delete button.

9) Type msconfig in Search box, choose Run as Administrator, from Services tab ensure that Microsoft Store Install Service is checked, if not restart PC.

10) If these all fail then go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done:

Start with Step 4 to turn off Startup freeloaders which can conflict and cause issues, then Step 7 to check for infection the most thorough way, then step 10 to check for damaged System Files, and also Step 16 to test a new Local Admin account because of the serious and persistent problem with corrupted accounts. Then continue with the other steps to go over your install most thoroughly.

11) If nothing else works then do a Repair Install, by installing Media Creation Tool, open tool and choose to Upgrade Now. This reinstalls Windows while keeping files, programs and most settings in place, and is also the most stable method to advance to the latest version.

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
