Windows 10 error 0x800F081F usually appears in recent upgrades or installs where the .NET framework 4.5 is installed by Windows but programs you later install require version 3.5. For some reason, version 3.5 isn’t installed by default and can occasionally have trouble downloading the update from Microsoft. Fortunately, it is simple to fix the Windows 10 error 0x800F081F.
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.
- Run Windows Update and make sure you have all the latest updates.
- Open a CMD window as an administrator.
- Type or paste “sfc /scannow‘ and hit Enter. This will check file integrity.
From Windows 10 installation media:
- Open the PowerShell Console as an administrator.
- 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.
