The problem
Windows' recovery environment breaks in ways that don't announce themselves. KB5034441 and its successors needed a larger recovery partition than most OEMs shipped — the update fails, and the machine is left with a recovery partition that's 50–200 MiB short. On Windows 11 24H2+, Device Encryption can grab a newly created partition before the recovery type GUID lands, and reagentc /enable then refuses with "Windows RE cannot be enabled on a volume with BitLocker Drive Encryption enabled." And on 12th-gen Intel and later, the recovery image needs the Intel VMD driver just to see the OS disk — miss it, and Startup Repair fails with INACCESSIBLE_BOOT_DEVICE.
None of these are obvious until the machine is already in trouble, and none of them are fixed by the usual "just run reagentc /enable" advice.
