Problems after installing 20H2

[mjw72652]

I just installed 20H2 with an in-place upgrade plus the latest updates on 2 HP laptops (different models). I have had no problems with the 15bs234wm, but I have several on the 15da0053wm. It has a 1 TB WD PCIe/NVMe which I installed just after completing the upgrade/updates, which I cloned from the existing 1 TB SATA hard drive. I disabled the Optane memory in the BIOS, then pulled the drive and the Optane to install the SSD.

I have two problems on the 15da- 1.) 5 of my 8 desktop gadgets won't display properly any more (they all still run just fine on the 15bs) 2.) My notification area won't stay open for me to read notifications- it snaps shut as soon as I move the mouse up into it (the 15bs still works just the same as it always has .

Does anyone have any suggestions? (The problems appeared before I switched out the SATA drive for the SSD, so it's not the drive.)

1. Run Windows Update Troubleshooter.
If you ever run into Windows update errors, one of the easiest yet effective ways to resolve the issue is running the Windows Update Troubleshooter. 

The Windows Update troubleshooter will terminate the Windows Update services, delete all the unwanted cached files, and restart the Windows Update services, thus solving the error in the process. 
 

Here is all that you need to do:

• Go to Settings and select Update & Security.
• Select Troubleshoot from the left panel.
• Locate Windows Update and click on it. 
• Finally, click on Run the troubleshooter and follow the on-screen instructions to complete the process. If the troubleshooter finds any issues, it will notify you and attempt to fix them automatically.
