REGRESSION: Update deletes HKCU input keys and breaks Text Input Service

Environment: Windows 11 (Latest Cumulative Update) Component: Text Input Management Service, Input Method Editor (IME), CTF Loader (ctfmon.exe), Settings GUI

Issue Summary: Following the deployment of the latest Windows 11 update, the system's localized input framework ceases to function. All installed language packs, keyboard layout assignments, and system-wide spellchecking/autocorrection settings are removed from the Settings UI and become inactive across the operating system.

Technical Details & Diagnostics: Investigation of the registry reveals that the update removes specific configuration keys governing text input. Specifically, the following registry path is affected: HKEY_CURRENT_USER\Software\Microsoft\input\Settings

The update deletes the EnableAutocorrection and EnableSpellchecking DWORD (32-bit) values from this location. Concurrently, the localized input framework fails to initialize correctly, with ctfmon.exe failing to hook into the language bar or load installed regional configurations.

Workaround Attempted: Restoring base functionality requires manual registry modification (re-creating the missing EnableAutocorrection and EnableSpellchecking DWORDs and assigning a hex value of 1), followed by a manual restart of the Text Input Management Service via services.msc.

Impact: This regression breaks core text input and language components out of the box after the update. It requires manual, system-level intervention (registry edits and service restarts) to resolve, which significantly impacts standard usability and productivity. Requesting a review of the update package to prevent the deletion of these registry keys in future deployments.
