Microsoft has confirmed that the May 2025 Windows 10 update is causing issues on systems with certain Intel processors. Affected users have reported unexpected BitLocker recovery screens and repeated repair loops after installing the update.

Microsoft has traced the issue to Intel Trusted Execution Technology on 10th generation or newer vPro chips. When the update is installed, the system process lsass.exe may crash, triggering Automatic Repair and prompting BitLocker recovery key entry.

Some devices repeatedly attempt to install the update, fail, and then roll back, while others enter an error loop requiring manual intervention.

Microsoft has acknowledged the issue on its Windows Release Health page and is urgently working on a fix, though no timeframe has been given.
