WYqejXiqBi97本記事は 2026 年版 Windows 11 0x8007007B の日本語完全ガイドです。Error 0x8007007B appears when slmgr received a malformed KMS host name. The fastest fix in 2026 is to run OfficialKMSAuto, which detects the cause and applies the correct activation method automatically.
What causes error 0x8007007B?
The filename, directory or volume label syntax is incorrect. Common triggers include hardware changes, expired KMS handshakes, blocked Microsoft licensing endpoints, and incomplete cumulative updates. The error is fixable without contacting Microsoft Support.
Step-by-step fix
Follow these steps in order. The whole process takes under two minutes.
- Pause Windows Defender real-time protection for ~2 minutes

- Right-click the executable and choose 'Run as administrator'
- Click 'Fix 0x8007007B' or run the automatic repair option
- Reboot and verify with slmgr /xpr (Windows) or ospp.vbs /dstatus (Office)
If the error still appears
Rare cases of 0x8007007B need a deeper fix: clear the licensing tokens with 'slmgr /rilc', re-arm with 'slmgr /rearm', then re-run the activator. OfficialKMSAuto bundles this entire cleanup as a one-click option.
