Haven't seen this posted anywhere yet, so I'll post it now.
In build 14915, Personalization ---> Colors displays for a second, then crashes. I've run into this on all of my Insider OS's, physical and VM. You may also have this issue.
The event log is:
[ Name] Application Error
- EventID 1000
[ Qualifiers] 0
[ SystemTime] 2016-09-03T10:49:05.103630400Z
There is a workaround. In C:\Windows\System32, take ownership of Windows.UI.Xaml.dll and rename it Windows.UI.Xaml.old.dll
Copy the Windows.UI.Xaml.dll from build 14905 to C:\Windows\System32. Restart and the Colors will not crash.
This will, of course, revert back to the bad DLL if SFC /SCANNOW is run, or an in-place repair is done.
If you do not have access to the DLL from build 14905, I have included a ZIP of it here:
Windows.UI.Xaml.dll.zip (From Pro 64 bit. Only one I have)
