This post will go over Group Policy settings in Windows 8.1 that you can disable for more performance, privacy, and security. This list is based off of the upcoming Windows 8.1 Updated v2. (Link here when finished)
There is nothing that I know of that would allow for batch applying these. I think you can only manually apply these.
To apply these, you need to be running Windows 8.1 Pro or Enterprise. Lesser editions don't have access to Group Policy. To open the Group Policy Editor, press the windows key, type gpedit.msc, and press enter.
These two are less security focused and more how I prefer things to function. You can skip these if you want.

You can access the below from User Configuration > Administrative Templates > Windows Components > File Explorer
Enabled:
Turn off the caching of thumbnails in hidden thumbs.db files
These clutter my network drive and make moving files a pain. I disable them as they're more annoying than useful. This doesn't effect the display of thumbnails.
Remove CD Burning features
This stops Windows from ejecting the CD/DVD drive if you click on it when it has no disk. It also disables useless CD Burning features.
