Problem Install Window 10 Updates on HP Pavilion G6

[Preach_Pow]

I need help with figuring out how to resolve problem with getting the latest Windows 10 update to install on my HP Pavilion G6.  It currently is running Windows 10 OS version 1903.  But I have not been able to successfully complete an update for sometime to the latest version.  The message I received was something like "install was not able to complete because one or more system files not available (unable)  to update.   Please help me.  Thanks.

My guess is that you are trying to use Windows Update to do that, right?  While that is often the easiest way, it is also the least reliable and the most prone to problems.

If it were mine, I would do the following :
1) Use this link to download and create Win10 install media: https://www.microsoft.com/en-us/software-download/windows10
2) insert that into your PC (do NOT boot from it), find the folder containing the media, select the setup.exe file, right-click that and select Run as Administrator.  This will start an in-place Upgrade which could then take a couple of hours to complete.

If you are presented with a window asking for a product key, down near the bottom is a entry you can click to skip that. Do NOT enter a product key, as it will reuse your existing key and when you finish and get back online, Windows will automatically reactivate.
