When creating a scheduled task in Macrium Reflect you may see the following error:

This error is caused by corrupt NTFS permissions applied to folder 'C:\Windows\Tasks' and prevents new tasks being saved.


To correct this error:

  1. Open a command prompt with elevated privileges. Please see Running an elevated command prompt

  2. Type the following commands:

    cd\
    cacls c:\windows\tasks /T /E /P Administrators:F
    cacls c:\windows\tasks /T /E /P SYSTEM:F
    
    

    Ensure that you press enter after the last line.

  3. This will grant 'Administrator' and 'SYSTEM' full access to folder 'C:\Windows\Tasks'

  4. Retry to create your scheduled tasks.
