Reports are saying MS is investigating this issue as of yesterday and it is affecting OS drives that are about 60% full yet only a handful of people will experience issues, such as the OS drive disappearing or corrupting.

The isolated issues are also coming from Japan.

And then we have Secure Boot certificates expiring in June 2026 which is another issue if you do not update.
