Trick to enable .NET Framework 3.5.1 without downloading anything

1. Open the .iso file of Windows 8 Consumer Preview with a compression / decompression software like 7-Zip. Open the Sources folder and find sxs folder. Now copy this folder to following location:

C:\Temp

2. Next run the Command Prompt as administrator, and type the following command:

dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:c:\temp\sxs /LimitAccess

That’s it!
Now reboot and check the Windows Feature window again. You’ll see the first option is automatically checked. You will now also be able to run software or app which requires .NET (like AutoCAD. etc), without any problems.
