I used this program several times but each time I want to update, this program found and download many updates. When I started to install them, it turned out that most of them are not applicable to my computer.
E.g. Now I have Windows 10 x64 1803 (17134.137).
After searching updates, WOU downloaded 15 updates with total amount of 4.24 GB
But only 2 of them with 33.8 MB (!) are compatible.
Why WOU downloaded extra 4 GB ?

wsusou downloads updates for all Windows 10 builds, which get updates from MS currently (10240 LTSB, 14393, 15063, 16299 and 17134).
MS does not make any difference between them in the catalog (wsusscn2.cab). All of them are listed as "Windows10.0".
So there is no way to dynamically download updates for one of them, but not for the others.
Your repo contains updated for all currently supported builds (usually 3 updates for each one [cumulative update, Flash Player update, Servicing Stack update]).

So why other programs work correctly - Windows Update Mini Tool and Dism++? They are always found only correct updates.

They have a different purpose (updating 1 system with definitely checked patch level) and you cannot compare them. WOU's purpose is to update many systems with unknown patch levels. Thus it needs to have everything "aboard".

Ok, I understand. Then last question. Is it possible to include this option in future release?

Only in case changes the catalog and actually starts making a distinction between Windows 10 feature levels. At it is now, they do not. Please note that you can always exclude updates yourself.

Bonus info:
DISM is a default MS tool (previously only in the development kits) that is extensively used by the WOU installer part. It attempts to install whatever you throw at it. All checking is done by Windows Update.
WUMT is only an alternative GUI/shell to Windows Update, it was developed because the one of Windows 10 sucks goat's nuts. Its Offline support is based on the same catalog WOU uses, however, WUMT is executed on the target system and thus knows what OS build you are trying to update.
WOU's download part is not run on the target systems, and thus cannot know what builds the installer has to update in the end. Thus, everything is downloaded. The installer then thoroughly checks the environment and skips everything inapplicable.

In your case, a solution like Portable Update would be better.

@boco
„Dism++“ is a „tuning“ tool for Windows, which also is able to slipstream updates. It can be compared to NLite or VLite for Windows XP/Vista.

I missed the ++ characters.

Dism++ by Mouri_Naruto is a replacement for the standard DISM, but with a GUI. It is one of the many projects that are maintained and supported on MDL (where I'm a member under a different name). The original DISM is from MS.
