Fix Windows 10 error 0x800F081F

To make the final step work you will need a copy of the Windows 10 installation media. Before that, try a couple of quick fixes that have been known to work.

  1. Run Windows Update and make sure you have all the latest updates.
  2. Open a CMD window as an administrator.
  3. Type or paste “sfc /scannow‘ and hit Enter. This will check file integrity.

From Windows 10 installation media:

  1. Open the PowerShell Console as an administrator.
  2. Type or paste “DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:e:\sources\sxs“.

Where you see partition, put the drive letter of the Windows 10 media. For me, this was “DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:e:\sources\sxs” as the installation DVD was in my E: drive.

One of these steps is sure to fix the 0x800F081F error. If you have any other tricks that work, just let me know lexvdhorst[@]
