Hello everyone, I am Palash Acharyya, Support Escalation Engineer with the Microsoft Platforms Core team. In the past decade, we have come a long way from Windows Server 2003 to all the way to Windows Server 2012R2. There has been a sea-change in the overall Operating System as a whole, and we have added/modified a lot of features. One of these is Disk Defragmentation and I am going to talk about it today.
