vCenter, Windows 2012 R2, .NET 3.5 issue

It is well know that vCenter Server 5.5 requires .NET Framework 3.5. It is quite easy to install it by Server Manager GUI or by following command: 
dism /online /enable-feature /featurename:NetFX3 /all /Source:d:\sources\sxs /LimitAccess
Command above assumes Windows 2012 DVD in drive d:
... but i had an issue with installation getting following error.
PS C:\Users\Administrator> dism /online /enable-feature /featurename:NetFX3 /all /Source:d:\sources\sxs /LimitAccess

I discuss this issue with our Microsoft Specialist and he already knew the root cause and fix. The root cause was some bad Windows update. It is already fixed by Microsoft and if you didn't do update in bad time you should not experience this issue. However, when you hit this bug the only solution is to run following Microsoft fix.
