Install .NET Framework 3.5 on Windows 10

I have found that after performing a clean install of Windows 10 that sometimes .NET Framework 3.5 is not installed.  I have run into scenarios where even though I had 4..6 installed I still needed 3.5.

If you have a non domain computer the quickest way to install 3.5 is to open Programs and Features and click on Turn Windows features on or off.  This will open another where you can turn on .NET Framework 3.5.

If you are on a domain computer, specifically a domain that is using WSUS, then the above procedure will probably not work.  This is due to the fact that the above procedure uses Windows Update to install the program.  Since WSUS redirects the PC to a different server the install package is not available.  To install .NET Framework in this scenario you will need a windows 10 install disc.  Insert the disc into you drive and open a Command Prompt as an admin.  In the Command Prompt window type the following command and press Enter:

dism /online /add-package /packagepath:E:\sources\sxs\microsoft-windows-netfx3-ondemand-package.cab

Make sure to replace E with the drive letter of you device.

Windows 10 – 1607 WSUS Problems

Did you upgrade your Windows 10 PC to 1607 also known as the anniversary update, only to find that it won’t install updates from your WSUS server?  If so join the club.  After some research, it appears that Microsoft figured out the issue and put in in their September cumulative update KB3189866.

To get this update to my network computers I had 2 options.  Since I couldn’t  get the affected PC’s to retrieve updates from my WSUS server, I either had to install the update manually or have each PC download the patch from Microsoft’s update servers.   I chose to manually install the patch since I could not afford the bandwidth required to have each machine downloading updates from the internet at once.

Once I manually installed the KB3189866 update, each computer was able to contact my WSUS server, download the remaining updates and install them.
