Windows 25H2 will be coming soon, but if you want to pass by now, the steps are very simple. First of all, we write Winver in the Windows Start menu and learn our current build number. We need to be in version 26100.5074. This version actually includes the features of the 25H2 version, but it is inactive. If our build number is lower than that, we open Settings and go to the Windows Update section. Here, the preview update with the build number 26100.5074 should appear. We install this update by saying "Download and Install". Then we restart the system and download and run the update file. After the process is finished, we restart it and run the winver command.
