Can't sync my ipodTouch4g with iTunes ATH.exe doesn't run

Question

Hi, I have a problem for about two months, iTunes 10.6.1.7 reconize my iPod only the first time, when I install it.
When I restart my computer (windows 7) iTunes can't see my iPod Touch 4G anymore. I tried different solutions from the Apple communities forum, but nothing  works.
I saw my active process in windows task manager, and I found the ATH.exe process, the first time when I install iTunes, everything works fine and this process is running... But when I restart my pc and when I connect my iPodTouch nothing happen (ATH.exe doesn't run), I don't know if the ATH.exe process is the problem or maybe I have something wrong in the windows registry.
I tried to start ATH.exe manually but doesn't work and nothing happen. If someone in the world have the solution please, reinstall windows7 again is a quite painfull I have many apps and music sync with my Ipod.
thanks.

Try this procedure:
1) Open Windows 7 Control Panel.
Navigate to the "Uninstall or Change a Program" application menu and list. 
Sort the application program list by clicking on the list header for the program PUBLISHER (second column). (resorting the program names may take a minute -- note the update status bar at the top). 
Locate ALL Apple applications in the list. 
Select each apple program in order with a RIGHT mouse click and select the REPAIR option if available.
When you have repair each program that is able to be repaired, then...
2) Reboot PC and hit the F8 key until Windows reboot screen comes up. 
3) Then reboot with Windows in "SAFE MODE with Networking"
4) After Windows comes up, Run I-tunes to sync.  You will get probably see errors -- answer YES to any error messages, or messages asking if you want to fix problems. (esp. USB problems)
5) exit I-tunes and reboot PC into NORMAL MODE (do not hit F8)
6) Start I-Tunes on the PC and try to sync the  I-Pod 4G
One last thing, (just in case you did not know): If your I-Pod locks up when your syncing  (after 5-10 minutes) to I-Tunes (sync screen or black screen), you should be able to unlock the I-Pod by holding down the power button and the menu button simultaneously and resync again.
Please post on here, and let people know if this worked for you.
Good luck.
I have similar (slightly different) problems that i am trying to fix.
