After upgrading to iTunes 12.3.1.23, I am no longer able to sync more than once. I have to reboot if I want to sync again.
Device Manager shows:
right-clicking on Apple Mobile Device USB Driver shows this:
Windows 10 1511 64-bit * iTunes 12.3.1.23 * iPod Classic 160 GB (7th generation)
iPod classic (120 GB), Windows 10, Actually, it's an iPod Classic 160
Norton anti-virus by any chance? This seems to be causing problems for some.
iTunes uses the iPod Service for iPod classic rather than the Apple Mobile Device Service. The message may well be due to an older 32-bit version of AMDS not removed then the 64-bit version was installed. You could try removing the current driver to see if the correct one will then load. Otherwise a full tear down and rebuild of iTunes might be in order. See the second box in Troubleshooting issues with iTunes for Windows updates.

Thank you for your response.
Norton Anti-Virus was my first thought, as Norton had had a problem which I experienced too. They resolved that one with their Sep 30 2015 (22.5.4.24) release (https://community.norton.com/en/blogs/product-update-announcements/norton-2254-p roduct-update-available-now). In any case, my current problem started when iTunes 12.3.1.23 was installed. It is not a Norton security product problem.
Uninstalling the Apple Mobile Device USB Driver and reinstalling it brings the iPod up as a generic storage device in Windows, but it is not recognized as an iPod by iTunes.
I updated the driver from C:\Program Files\Common Files\Apple\Mobile Device Support; it installed Apple iPod USB Driver, and prompted me to restart the computer.
After restarting, all was fine with the first sync. On the second sync, iTunes again did not recognize the iPod. In Device Manager, the Apple Mobile Device USB Driver again displays the above error (text copied here):
Windows cannot load the device driver for this hardware because a previous instance of the device driver is still in memory. (Code 38)
The driver could not be loaded because a previous version of the driver is still in memory.
Try stopping the AMDS service before trying to update the driver.
Try it in safe mode.
If you haven't yet uninstalled all Apple component and reinstalled try that.
Try temporarily disabling Norton and see if you can sync more than once in the same boot cycle.

tt2,
Stopping AMDS service before updating the driver made no difference. The updated driver version is the same as the uninstalled driver version, 6.0.9999.67 from 5/18/2015.
Windows 10 can't load the device driver when booted in Safe Mode.
I uninstalled all Apple components, restarted, reinstalled and restarted. The behavior is the same.
Temporarily disabling Norton does not let me sync more than once in the same boot cycle.

You could strip it all out again and install the "for older video cards" version. This may be more stable. Otherwise I think I'm out of ideas.

An update to iTunes 12.3.2 did not fix the problem.
Boo. 😠

Finally figured out the workaround to get an older iTunes (12.2.25) to read a newer (12.3.2.35) iTunes library.itl.
Voila! Your "newer" iTunes Library.itl will now work with the older version of iTunes.
This all happens a lot faster on an SSD drive.
Note: Synchronizing your iPod will take awhile for "Finishing sync." I believe the delay is due to newer version Genius results having to zapped and reGeniused with the older version, then deleted from the iPod and re-synced.
Note to self: Do not update iTunes again without backing everything up. My faith in Apple is touching, but naïve.
See Backup your iTunes for Windows library with SyncToy for a backup regime.
It isn't every update that changes the internal structure of the iTunes database. I suspect that your steps worked because there was no change.

Actually, it still doesn't work. iTunes 12.3.2.35 still doesn't recognize the iPod Classic after the first sync. The error is still
Windows cannot load the device driver for this hardware because a previous instance of the device driver is still in memory. (Code 38)
The driver could not be loaded because a previous version of the driver is still in memory.
And it's only fixed (and for one sync only) when I restart Windows.
If you're still running Norton this might be interfering with the way the device drive is loaded and unloaded. I've read other threads where people have suggested they are good for just one sync per boot up. You could test by temporarily disabling Norton and rebooting, then see if you can sync multiple times.

Turning off Norton Anti-Virus doesn't change the behavior.
Did you reboot at as well?
tt2
Yes. I have been a customer-facing computer technical support engineer for over 25 years. Please assume I have read your entire response.
In device manager there should be an option View > Show hidden devices. If you enable that you may be able to uninstall any and all drivers that appear to belong to Apple, then see if your devices connect properly thereafter.
Reading the post from Dec 1 and your response to it I'm still not certain if you've tried the iTunes for Windows (64-bit - for older video cards) release. This is a 64-bit installer for mostly 32-bit code similar to all 64-bit versions up to 12.1. There is a slim chance it may behave differently. Apologies if you've already tried this.
If neither of those help then I'm stumped.

iTunes 12.3.1.23, iPod Classic & Windows 10: Can sync once, then must reboot
