Hi, I want to say in advance that I thank you for WSUS project!

The new WSUS version is not supported Windows XP update. So I used: WSUS v9.2.1

I chose czech language and start.

wsusoffline-csy-x86.iso
wsusoffline-wxp-csy.iso

I have two iso files and I do not understand what is the difference between them?

You activated both checkboxes (One ISO per OS+lang and one ISO all x86 OS). The first creates an ISO just for your XP (wsusoffline-wxp-csy.iso), the second one normally creates an ISO for all selected x86 OS combined (wsusoffline-csy-x86.iso). Since you only have activated that one OS, there is not really difference between them, in your case.

You really only need to activate the first (per OS) checkbox if only one OS is selected.
