What Causes Error 0x800f081f?

Fixing the Problem – Step-by-Step

Below are several methods you can try to resolve this issue. You may need to use one or more depending on the root cause in your specific case.

1. Use the Windows Features Installation Media

If you’re trying to install .NET Framework 3.5 and encounter this error, using the original installation media can help bypass the problem:

Insert your Windows installation media (DVD or USB).
Open Command Prompt as Administrator.
Type the following command and press Enter:

Dism /online /enable-feature /featurename:NetFx3 /All /Source:D:\sources\sxs /LimitAccess

Make sure to replace D: with the actual drive letter of your installation media.

2. Run DISM and SFC Tools

Corrupted system files are often responsible for this error. Running DISM and SFC (System File Checker) can repair them:

Open Command Prompt as Administrator.
Type the following command and press Enter:

DISM /Online /Cleanup-Image /RestoreHealth

After DISM completes, run:

sfc /scannow

Wait for both checks to finish, and then reboot your system.

3. Check Windows Update Settings

Sometimes the error is due to existing issues with the update components. Resetting Windows Update can resolve the problem:

Open Command Prompt as Administrator.
Execute the following commands sequentially, pressing Enter after each:

net stop wuauserv
net stop cryptSvc
net stop bits
net stop msiserver
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
ren C:\Windows\System32\catroot2 Catroot2.old
net start wuauserv
net start cryptSvc
net start bits
net start msiserver

Once completed, try installing the update or feature again.

4. Enable .NET Framework from Control Panel

Sometimes enabling the .NET Framework manually can avoid dependency issues that trigger the error:

Press Windows + R, type appwiz.cpl, and hit Enter.
Click Turn Windows features on or off.
Check the box next to .NET Framework 3.5 (includes .NET 2.0 and 3.0).
Click OK and allow Windows to download the required files.

Perform a Windows Repair Install – This reinstalls Windows while preserving your files and applications.
Check for Malware – Use a trusted antivirus or Windows Defender to perform a full system scan.
Contact Microsoft Support – For persistent issues, a certified technician can assist further.
