Microsoft .NET Framework 4.8 for Windows 7 in Win Toolkit Addons Posted July 20, 2016 I'll make it short: DO NOT TOUCH THIS ADDON. Why? For example, have look into "NDP461-KB3154529-x86-x64.reg" This is just one sloppy piece which is capable of cross-contermining systems. The .reg contains ABSOLUTE PATHs, "C:\windows\". Now what will happen if you setup windows on D: -- next to your current one ?. How long will it take to screw up BOTH systems, because trying to clean the setup on D:\ also screws with c:\ Now what are the odds, since the author couldn't be bothered to use %windir%, that everything else is as sloppy ? I'll advice everyone to setup chocolatey at at startup batching everything crucial - like "choco inst powershell" would deal with everything: removing wMF4, insfalling WMF5, DOTNET4.5 and Powershell 5..
