Which processes / services need to be running to perform a local sync with an iPod Touch iOS5 with Windows 7? I'm running Windows 7 Ultimate 64-bit and the wifi sync used to work properly, but due to lack of memory, I shut down some of the processes / services that would run automatically to make my computer run a bit faster.

Now I'd like to sync my iPod Touch with iOS5 again but I don't know which services need to be turned on to sync again.

When I go to my iPod to sync, the button for wireless syncing in Settings isn't tappable.
Okay so here are the prerequisites for making this work over wifi:
Prerequisites:
Programs Running:

iTunes

Services Running:
(Located in Start-&gt;Control Panel-&gt;Administrative Tools-&gt;Services)

Bonjour Service
Apple Mobile Device Service

wifi:

iPod connected to wifi and so is your computer

iTunes Issues:
If you have all of the prerequisites above set, and on your iPod you enter (Setting-&gt;General-&gt;iTunes Wi-Fi Sync) and you find the Sync Now button is still disabled do the following:

In iTunes click edit-&gt;preferences
Click the Devices tab.
Click the Reset History button.

Now if you look at your iPod Touch again the Sync Now button should now be enabled.
