Windows 10: Winver shows two different versions on two machines

I have Win 10 installed on two machines.

The first, an HP Laptop, came from the factory with W10 and quickly updated itself to version 1511 OSbuild 10586 according to Winver.

The second, a Dell Destop, was updated from Win 7 to Win 10 back in December and after the latest update yesterday shows version 10 Build 10240 according to Winver.

Why the difference? Shouldn't they be the same?

Thank you.

Display issues on two different Nvidia machines caused by most recent update

Yes I have downloaded the Nvidia Geforce experience and downloaded all latest updates, which unfortunately did not resolve my problem. I then tried the steps in the other thread for AMD and tried uninstalling the device from device manager when in safe
mode and then allowing it to reinstall but am left with the same issue.

It is strange that this is affecting two entirely different machines. Are there any other suggestions?

 

Display issues on two different Nvidia machines caused by most recent update

We appreciate your time responding back to us with more details. Since updating the drivers won't resolve the issue, we suggest that you roll back the display drivers of your PC. We'd like to know if you can access the
Device Manager.

The Device Manager has the list of your drivers that you could either update or roll it back. To access the
Device Manager, Right-click the Windows icon > Select
Device Manager > Click the drop-down icon beside the Display adapters > Right-click your graphics driver and select
Properties > On the Driver tab, select
Roll Back Driver.

Let us know if the above resolution fixed the issue.

 

Your HP gets the most current build, 10586. It must have been updated BEFORE Nov 21st.
Your Dell gets the older build, 10240. It was updated on or AFTER Nov 21st.

The reason :
Version Windows 10 10586 was released by Microsoft about a few days ago. Then on November 21st, MS took it off and replaced it with the older version 10240.

Microsoft has tried to explain, but the attempt is feeble, at best. To me MS does not make sense, period.
Presumably, the new 10586 will be released through Windows Update again ..... soon.

 

Thank you very much. That is a clear explanation.
