I get an error message that Windows System Restore failed?

If you look just above at the last few messages, system restore works on updated builds of Windows.  It tested it and didn't have any issues and another person confirmed it.

To clarify, we weren't able to reproduce this internally, so it's a little uncertain what's going wrong - and that also means we weren't able to fully verify the fix. In my testing, system restores all worked fine (both before and after the fix).

To answer your earlier question, we went thru the posts in this thread, collected a list of the likely offending files, and made sure we proactively clean those up from the .dropbox.cache folder - such that they can't possibly interfere with the system restore (they don't exist!). Supposing our theory on what's causing this is correct, that should fix it, at least when restoring to a point _after_ the updated Dropbox client has run this cleanup proceedure.

If anyone is still able to reproduce this, that would be helpful to know.

To clarify: The fix was something that either Microsoft or Dropbox could have implemented. It was more on Microsoft though because System Restore shouldn't crash because of one App.  I filed a bug on this using Microsoft's Feedback Hub and they appear to have fixed it.
