How to reduce Volume size? Common way (Control Panel – Volume, Choose Volume, push “Edit” button) doesn’t work. In “Edit” window when I try to print less capacity I have (See picture) and press “Confirm”, I see note “Operation succeed”, but nothing changes.

How to decrease Volume size?

The size of the volume can only be increased, not decreased. In the case that your storage pool still has space.

Sorry, you just can't.

In most storage scenerio's, volume shrinkage is not allowed because data is not always written from 'front-to-back' in a partition. Assuming you have the available space, you can

1) create a new volume of the desired size
2) move the data to the newly created volume
3) remove the old volume

This said, recent Windows OS can shrink a partition/volume but best to do a proper defrag first. Some storage systems 'say' they can shrink a volume/partition but they are really doing steps 1-3 I just posted in the background.
