The Restartless Update: Microsoft Tests Unusual Windows 11 Build That Installs Without a Reboot
Ddos 
Microsoft has recently released a new test build for participants in the Windows Insider Preview Program — namely Windows 11 Dev Build 26220.7052 and Windows 11 Beta Build 26220.7052 — both of which are rather unusual editions.
Their uniqueness lies in the fact that these builds can be installed and fully upgraded without requiring a system restart, unlike standard versions, which must reboot to complete the update process. The trade-off, however, is that these builds introduce no officially announced new features or changes.
Previously, Microsoft had experimented with reboot-free cumulative updates for select enterprise users — updates that applied patches without the need for a system restart. Under this approach, devices would only need to reboot up to four times a year (roughly once per quarter), rather than after each monthly update.
However, this newly released test build does not appear to be directly related to those reboot-free cumulative updates. Microsoft has not explained the specific purpose of this version, merely stating in its official announcement that it was released “to test the processes of this program.”
Of course, one might speculate: perhaps Microsoft is working to improve the installation and update mechanism of Windows 11, allowing future personal and home users to upgrade their systems without frequent reboots. For now, such assumptions await further confirmation from the company.
There are also rumors suggesting that the Windows 11 Dev Channel will soon become an exclusive testing platform for Windows 11 version 26H1 — another special release intended solely for AI PCs powered by Qualcomm Snapdragon X2 processors. Conventional x86-based PCs are expected to receive their corresponding update later, with the 26H2 version scheduled for release in the autumn of next year.
