Task Manager - what have I done?
Windows 7 Home Premium.
Task Manager used to display Processes, Services, Performance, Networking and Users (in addition to Applications).
Something happened (I clicked on something) and now I only have Applications (and no headers to click on).
I've rebooted (including a forced shutdown) - all to no avail and no combination of right or left clicks has any effect.
I miss the extra facilities - how can I restore it to 'normal'?
