OneDrive sync 64-bit for Windows now in public preview

Mark Anderson Fair question. 

OneDrive is currently the largest 32-bit process in-box in Windows in terms of memory usage and accounts for almost two-thirds of SysWOW64 image pages references post boot. Moving to a 64-bit client prevents 10s of MB of SysWOW64 binaries from being pulled into memory. It also allows OneDrive to benefit from sharing binaries with other 64-bit processes.

While having more memory available might improve some OneDrive scenarios, we do know that there are other bottlenecks that might be encountered first. As a result, there are no changes to file limit guidelines.
