If your Security Center installation on a
Windows 10 machine is interrupted with the return code 0x800f081f, you must use your Windows
10 installation disk (or a virtual copy of it) to turn on .NET Framework 3.5, and
rerun the Security Center installation.
What you should know
Security Center requires the feature .NET
Framework 3.5 to be turned on in order to work.
Security Center installer turns .NET Framework 3.5 on
by default. However, this feature cannot be turned on if you are missing the .NET 3.5.1
files, which causes the error 0x800f081f.
Procedure
-
Get a copy of the Windows 10 installation disk (or a virtual copy of it) from
your IT department, and make sure it is accessible from the computer where
Security Center needs to be
installed.
-
Open a command prompt with full administrator rights.
-
Enter the following command:
DISM /online /enable-feature /featurename:NetFx3 /All /Source:F:\sources\sxs
where F: is the drive letter where the installation disk or
virtual disk with the Windows 10 setup files are located.
The command prompt will run through a repair and activation of the .NET
framework feature.
-
Close the command prompt.
-
From the Windows Control Panel, open the Programs and
Features applet and click Turn Windows features on or
off.
-
In the Windows Features dialog box, click .NET
Framework 3.5, and then click OK.
