QUESTION While optimising my PC I came across some fascinating bits of software called services. Can I safely disable any that don't sound useful to me, such as Routing and Remote Access? Alan Sears

HELPROOM ANSWER Definitely not. These services are important to Windows and ensure all aspects of the OS work correctly. Each service is an application that controls an aspect of Windows functionality, such as internet access or printing.

Disabling services can even prevent the PC from starting up in the first place. A list of Windows services and what each does can be found here.

However, we don't recommend you disable any services unless you're instructed to by a Microsoft advisory or a technician.
