Issue Timeline:
  1. Computer has been running noticeably slower lately
  2. Tried running TronScript (it worked for me before), can’t run because I’m missing Microsoft .NET Framework 3.5
  3. Tried installing .NET Framework 3.5 through Windows Features (it hangs/freeze during installation)
  4. Tried installing .NET Framework 3.5 through DISM and receive an 0x800f081f error
  5. Tried installing .NET Framework 3.5 through Windows Features in Safe Mode (0x8007043C error) can’t run in Safe Mode


On the Microsoft website:

How To Fix 'Error 0x800F081F' During .NET Framework 3.5 Installation on Windows 10 - Microsoft Q&A

  • Tried running Group Policy Editor, but it says I do not have access even though I am the administrator on the Computer
  • When I checked C:Windows\System32, I seem to be missing the Group Policy Folder

I can’t help but think this is all related to a bad Windows Update that's preventing all supplementary update/installs. Can anyone please help guide me through? I've been trying for a couple of months now. Essentially all I want is to be able to install Microsoft .NET Framework 3.5
