When syncing apps, Itunes 12.2.1 is causing Windows 8.1 system to shut down and restart.
I've downloaded a fresh install of Itunes (12.2.1 - 64 bit) and it seemed to be fine until I went to sync with iphone 5.
Thoughts?
iPhone 5, iOS 8.4
For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach.
Review the other boxes and the list of support documents further down the page in case one of them applies.
The further information area has direct links to the current and recent builds in case you have problems downloading, need to revert to an older version or want to try the iTunes for Windows (64-bit - for older video cards) release as a workaround for installation or performance issues, or compatibility with QuickTime or third party software.
Your library and device backups should be unaffected by these steps but there are also links to backup and recovery advice should it be needed.
If the issue persists and you have a 64-bit system try the for older video cards version which is a 64-bit installer for mostly 32-bit code, similar to all 64-bit versions of iTunes up to 12.1.

just an update in case anyone at Apple is listening:
I went through all of the steps outlined in the second box of the troubleshooting for windows guide. Uninstalled and removed all of the Itunes files, bonjour, etc. Ran as administrator. The same problem occurred. Windows shuts down every time. Beginning to wonder if I don't have a virus on my phone.
Anyway, I then uninstalled and removed all the files again, and tried 12.1 version for older video cards. Plugged in the iphone 5, it recognized it right away, I tried to sync apps, and it crashed itunes.
Is your media folder stored on a NAS by any chance? That seems to cause a problem for some.
