After the update from Windows 8.1 to Windows 8.1 pro all programs were deleted.
At the update dialog they said that you have to reinstall all apps. I understood this to mean only the apps in the store.
Unfortunately windows have not created a recovery point.
Is it possible to go back to windows 8.1 preview by recovering the old partition table?
Unfortunately, the migration to Windows 8.1 was permanent. You cannot go back to the old preview or anything, the data was removed after you upgraded. You will have to reinstall all your applications. The partition table has nothing to do with your apps, as the partition the preview was on will have been erased and replaced with the new 8.1 data.
