Microsoft releases Windows 11 Build 25145.1011 in the Dev channel » Community

Microsoft has released cumulative update KB5016159 for Windows 11 Insider Build 25145 available on the Dev channel. This update does not bring any innovations and is aimed at testing the maintenance system. In particular, the company is testing the possibility of releasing and installing updates on top of previous updates.

After the update, the system build number will change to 25145.1011.rs_prerelease_flt.220617-1544.

Note that the maintenance system is one of the key components of the operating system, which should work as stably as possible, since it is it that is used to distribute functional and cumulative updates.

Important! Recently, builds under the Windows Insider program have become unavailable to users from Russia and the Republic of Belarus, probably due to geo-blocking. Windows Update simply doesn’t find new updates, whether it’s a build in the Dev channel or a cumulative update in the Beta or Release Preview channel. If you are affected by this problem, then enable the VPN by selecting any European country, check for updates in Windows Update, wait for the download to begin, and disable the VPN. You can read more about this situation in our article.
