I've been experimenting just using Sysprep without Audit Mode (in cases where you might have a computer lab with only one generic user and you want all the computers in the lab to be 100% identical to each other). If anyone wants to reproduce the complete breaking of Windows 10 x64 Pro (Build 101240), do this:
1. Install Windows and go through all prompts. During installation, create a local user named "test1." Otherwise, take all default installation settings.
2. When Windows installation is finished, login to the "test1" user account.
3. Restart the computer.
4. Log back into the "test1" user account.
5. Sysprep with these switches: /generalize /oobe /reboot
6. During the OOBE, take all defaults except create a local user named "test2." You won't use this account, but OOBE requires a user to be created.
7. When OOBE is complete, login to the "test1" account.
8. Click the "3D Builder" tile. It opens for a second and then closes.
9. Click the "Get Office" tile. It opens for a second and then closes.
10. Click the "Get Skype" tile. It opens for a second and then closes.
11. Click the "Microsoft Solitaire Collection" tile. It opens for a second and then closes.
12. Click the "Phone Companion" tile. It opens for a second and then closes.
13. Click the "Windows Feedback" tile. It never attempts to open.
14. Click the "Store" tile.
15. Click the "User" icon beside the search box.
16. Click the "Downloads" link.
17. Notice that the Store is (usually unsuccessfully) attempting to update all the Modern apps, whether they need to be updated or not.
