Windows Update error (Your device is missing important security and quality fixes)
Hello Arush47
Please run the below commands in CMD. Ensure you run CMD as an admin. These commands will delete the Windows Update registry log on your machine and then next time you click on check for updates, WU will check against the entire WU database.
Reg delete HKLM\Software\Policies\Microsoft\Windows\WindowsUpdate
yes
Net stop wuauserv >NUL
Cd C:\windows
rmdir softwaredistribution /s /q
Net start wuauserv >NUL
I am sure this will help. Let me know how you get on.
Thanks,
Jose
I got a response: ERROR: The system was unable to find the specified registry key or value.
I double checked the instruction line. Looks correct. Windows 10 will still not update....JosePinos55no errors doing each command. Rebooted 2 times after just incase. Did not fix the issue.
JosePinos55 It says "Access is denied"...
JosePinos55 This worked perfect for me, but I am trying to figure out a way to run it across several machines at once. I dont know how so many machines ended up in this state as I am new to my role here but I know it has worked on about 15 machines I have ran this against. If anyone has a suggestion for me to chase I am very greatful for any guidance you may have for me.
JosePinos55 The registry key \HKLM\Software\Policies\Microsoft\Windows\WindowsUpdate gives an error "Invalid Key" in Windows 10 Pro. Is there a different key for this version of Windows?
Thank you.

You can try these methods to troubleshoot your Windows 10 update issue:
Method 1: Run SFC Scan.
To run an SFC scan, follow these steps:
Run Command Prompt as Administrator.
Type sfc /scannow and hit Enter.
This will check and run an auto-repair on the issue.
Method 2: Run DISM Tool.
After running the SFC scan and the issue still persist, run the DISM to check the system health and to try restoring the files. To run DISM tool, follow these steps:
Run Command Prompt as Administrator.
Type the following commands:
DISM.exe /Online /Cleanup-image /scanhealth
DISM.exe /Online /Cleanup-image /Restorehealth
NOTE: This might a while to finish scanning. Do not cancel.
Method 3:
After doing Method 1 and Method 2 but the issue still persist, you can manually reset the Windows Update Components and Run Windows Update process again.
Resetting Windows Update Components will fix those corrupted Components and will help the Update installation quickly. To reset Windows Update Components, follow these steps:
Run Command Prompt as Administrator

Net stop wuauserv
Net stop cryptSvc
Net stop bits
Net stop msiserver

Restart your computer and try to install Windows Update.
Let us know how it goes.One = Failed. Some kind for critical failure
Two = timed out. Some kind of redundancy scanning loop. scanhealth got to 4.8% and then just froze a while.
Third = All the stops worked. The folders were renamed. I clicked through the GUI and saw the renamed folders. I restarted the services as you wrote. Rebooted. Started windows update and it's been Checking for updates... for about 45 minutes and still going. The red letters of Your device is missing important security and quality fixes. is still there.
Would you have any other advise?
