iTunes 10.5 CPU Issue

After the recent iTunes update (10.5) I noticed the


was suddenly chewing up CPU – everything still seemed to be working, I could still sync devices, it was just grinding the PC towards an early grave.

A bit of Googling suggested it’s a common problem and previously a reinstall of iTunes was the suggested fix – unfortunately this didn’t work for me, nor it would seem for a lot of people at version 10.5.

What did work for me was doing a

netsh winsock reset

from a command prompt (as Administrator) followed by a reboot.

Apparently the Windows TCP/IP stack can get corrupted and this will reset the Winsock Catalog to its default state – i.e. one that works properly.

It certainly fixed my iTunes problem and as a bonus the PC now boots faster and general network performance seems to be improved – one to remember!
