To all of the questions above, PowerShell will come to the rescue.

In Windows Task Scheduler the only thing you want to see 0X0, which basically means operation has completed successfully. Other than 0X0 means something went wrong and needs to hone your troubleshooting skills.

For network adapters it goes the same way as well. PowerShell script below reads the Windows
