When does the grace period change from 90 to 10 days (and from when)? I upgraded from 7 to 10 on July 26 and show no updates, Anniversary or otherwise. It has been 13 days since then and my computer shows no Roll-back available. Is my 10 days up?
Do you want to do the Anniversary Update? Or do you want to roll back to Windows 7?
If you want the Anniversary Update, use the Windows 10 Upgrade Assistant
It's not really a "grace period". You can rollback any time you like after any period of time, if you perform a system backup and restore that backup.
There is a 30 day period, however, where you can automatically rollback. There are, however, certain things that can happen that can make it so you can no longer roll back (I've had it happen too) even before your 30 days is up.
There has been rumor that MS is blocking automatic updates to the Anniversary update for 30 days for any new installs within 30 days of July 29th, because otherwise the rollback to the previous OS would be lost. But, it sounds like you may have done something to lose your rollback anyways.
The rollback is a nice feature, but shouldn't take the place of a full backup and restore. Too many things can break the rollback.
