About this tag
On WindowsForum.com, the tag 'msr' primarily refers to the Microsoft Reserved Partition (MSR), a small partition created during Windows installation on GPT disks. Discussions cover managing MSR partitions with Diskpart, understanding their role in Windows 7, 8, and 11 installations, and whether they can be safely deleted. A few threads also reference Microsoft Research (MSR) projects like MAUI, Revisions, and Lightspace, exploring mobile computing, concurrent programming, and interactive surfaces. These topics are less common but appear alongside the partition-related content.
