Windows 10 - Some parts of the UI not working after the latest cumulative update

I'm running Windows 10 build 18362.295. Last day i checked for updates and installed the available cumulative update including the OS security updates. After the installation of these updates i started facing the below issues which happens often (sometime everything is working properly)

• Some parts of the GUI (on every window) is not working




• I'm not able to use my touchpad gesture controls




• Not able to click task bar icons, start button or anything on my task bar




• It automatically triggers right click

I tried these methods to solve the issue:

• Tried uninstalling the latest cumulative updates, visiting Installed updates. But it is not showing uninstall option. I also tried the command line method but that too didn't work.




• I ran these commands and restarted my PC,

sfc /scannow
DISM.exe /Online /Cleanup-image /Scanhealth
DISM.exe /Online /Cleanup-image /Restorehealth
DISM.exe /online /cleanup-image /startcomponentcleanup

As per View update history i have,

2019-08 Cumulative Update for Windows 10 Version 1903 for x64-based Systems (KB4512941) (2)

As per Installed Updates

 Update for Microsoft Windows (KB4512508)

I'm able to do all UI interaction using only keyboard, but not able to do the same using my external mouse or touch pad. As already mentioned these issues started after the recent updates. I tried searching google, but no where i found any useful information or problem similar to this.

Update

As pointed out by @john, i was not on the latest build. So i checked for updates again and installed updates.

Now the View Update History window shows this,

2019-08 Cumulative Update for Windows 10 Version 1903 for x64-based Systems (KB4512941)
2019-08 Cumulative Update for Windows 10 Version 1903 for x64-based Systems (KB4512941) (2)

And Installed Updates window shows this,

Update for Microsoft Windows (KB4512941)

I'm now on the latest build 18362.329

Answer

As @John commented.

I downloaded Windows 10 to USB using the Media Creation Tool and Windows Updates Show/Hide Tool.

Then, i just run the setup.exe file with Airplane Mode turned ON. I don't know why but it prompted me to install the upgrade (I had checked my About Your PC it was showing Build 18362.239)

After the upgrade, i ran the wushowhide.diagcab which allowed me to hide windows updates.

Everything works fine now.
