The Microsoft services, also known as the Microsoft XML Core Services, are a set that enables applications written in Visual Basic Script, using Microsoft development tools, to build Windows-native XML applications and systems. In other words, MSXML files are responsible for QuickBooks Desktop to run imperatively or cause damage to the software. The msxml6.dll file requires registration in the CMD to initiate the registration process.
