Hi there, When I edit the [Components] section of winnt.sif, the dot NET packages still install! Mine looks like this: .... [Components] ; WinRM = off ; PowerShell = off ; PowerShellISE = off ; MicrosoftUpdate = off ; Silverlight = off ; DirectX = off ; MDX = off ; MSXML4 = off ; WDSearch = off ; IMAPI2 = off ; ICCDSCD = off ; WgaNotify = off ; WRMC = off BitLockerToGo = off ; BrowserChoice = off netfx11 = off netfx30 = off netfx35 = off netfx40 = off .... But when I check my fresh installation using asoft.be's dot net checker, I am still showing 1.1, 2.0, 3.0 3.5 and 4.0 as installed! Any clue as to why they are not installing as expected? The reason I want to exclude the dot NET packages is because all my CD's customized using OnePiece's update packs REFUSE to install any new dot NET updates through Microsoft Update. It only works if I uninstall 3.5 and then re-install it. However, by then, my fresh install already feels like it's been around for 6 months and not wisely handled. Any and all help will be appreciated! Thanks!
