KB5015814Broken
Start menu broken, .NET apps crash, boot loops
What broke
July’s Patch Tuesday broke the Start menu — again. It also crashed .NET Framework 3.5 applications, which includes a surprisingly large number of business applications. Boot loops hit some users. XPS Viewer broke. IE mode tabs died. The Start menu breakage would persist through the preview update KB5015882 that followed, making July 2022 the month where Microsoft spent three weeks unable to make the Start button work. PCGamer’s coverage was simply titled “Windows 11 security patch problems,” which at that point was barely even news anymore.
