Microsoft Update catalog

Question

Hi All,

I'm trying to download the Windows 10 update KB5003173 from the Microsoft Update Catalog (Link: https://www.catalog.update.microsoft.com/Search.aspx?q=KB5003173) and I'm getting a bit confused at to which entry to choose.

First off, my PC has an Intel(R) Core(TM) i7-4790 CPU and is running Windows 10 Pro version 20H2 OS Build 19042.985. As far as I know the CPU is a 64 bit processor.

If I select the option "2021-05 Cumulative Update for Windows 10 Version 2004 for x64-based Systems", which I thought might be the right one, it pops up a windows stating that the Architecture is AMD64.

If I select the option "2021-05 Cumulative Update for Windows 10 Version 20H2 for x86-based Systems" it pops up a window stating that the Architecture is X86.

Can anyone tell me which option I should choose given my CPU and Windows 10 configuration, please?

Kind regards.

Answer 1

I don't understand the difference between x64-based systems and x86-based systems

x64 == 64 bit operating system
x86 == 32 bit operating system

For this purpose AMD64 and x64 are now one and the same

Answer 2

Sounds like it would likely be this one
2021-05 Cumulative Update for Windows 10 Version 20H2 for x64-based Systems (KB5003173)

but the simplest solution may be to turn on automatic updates and let it happen automatically.
