It appears that the lack of updates you are experiencing may be due to the announcement regarding Windows updates. According to the recent announcements, there will be no December 2025 non-security preview update due to minimal operations during the Western holidays and the upcoming new year. Normal monthly servicing for both security and non-security preview updates will resume in January 2026. This could explain why you have not received any updates since December 10, 2025.
You may want to check for updates manually in the Windows Update settings to ensure your system is up to date, but it is likely that you will need to wait until January for the next set of updates to be released.
