Installing .Net 3.5 on Windows 10 offline using DVD/ISO media

Installing .Net 3.5 using the Control Panel in Windows 10 (anniversary update) can sometimes be very slow. Alternative option is to install from DVD/ISO, like:

c:\>DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:E:\sources\sxs

Where:
E: is the drive letter of DVD/ISO
