KB5127936, out October 28, clears error 0xC000000D on hosts with Administrator protection; Windows Server is not affected.

Microsoft fixed a Windows 11 regression that blocked non-administrator Remote Desktop connections when Administrator protection was enabled. The failure started with KB5124010, the September 22 non-security preview tied to OS build 26200.9550 on Windows 11 25H2, and could show error 0xC000000D. Microsoft opened an investigation on October 13 and marked it resolved on October 28. No CVE or exploitation is described; the fix is a preview update, not an out-of-band security patch.

Key facts
  • Affected clients are Windows 11 24H2, 25H2, 26H1, and 26H2.
  • Devices on KB5127936 or later do not need the workaround.
  • Until patched, admins can reset User Account Control Type Of Admin Approval Mode via Intune or Group Policy.
  • Administrator protection is on by default in several Windows 11 security baselines.
