hypervisor crash fixes

The hypervisor crash fixes tag covers Windows 11 Insider Beta updates focused on virtualization and system stability. The currently indexed content centers on Microsoft’s Build 26220.8690 for the Beta Channel, which addresses HYPERVISOR_ERROR and KMODE_EXCEPTION_NOT_HANDLED crashes reported in current 25H2-era Insider flights. It also notes related reliability work for the Start menu and the Settings app’s Startup page. This archive is useful for readers tracking Windows preview builds that improve kernel and hypervisor behavior, reduce startup-related instability, and clarify which fixes are intended for testers rather than general-release installations. Coverage may be limited to this specific Insider update and its associated stability changes.
