Solved: Corrupt scheduled tasks after roll backup to Windows 7 or 8.1 from Windows 10

What's this for?

Windows has a feature called Scheduled Tasks that is primarily for system tasks to run in the background. 

Often reverting to Windows 7 or 8.1 from Windows 10 will mess up all the Scheduled Tasks. 

The solution below may fix the following situations:

• Windows 7 backup gives error "Task image is corrupt or has been tampered"
• Software won't update automatically

Solution

1. Download RepairsTasks.zip
2. Open and extract all files or RepairTasks.zip
3. Open RepairTasks.exe
4. Scan for errors. If there are none, no further action required.
5. Before attempting Repair, use Backup Tasks to save the current state of the task files.
6. Repair with the 'Recycle existing tasks' radio button checked.

Note

Reverting from more recent Windows 10 builds seems to leave a list of 11 tasks unrepaired, reported by Scan as 'not installed' . They are Windows 10 tasks without a Windows 7 equivalent, and can be safely left alone. They are listed here: Windows 10 only tasks.
