Windows 10 build 10525

This build is the first post-RTM Windows 10 build to be released by Microsoft. It is also the first Threshold Wave 2 preview release. This build is also the first preview build to come at the very beginning of a fresh development cycle. This build is very much a baseline for further changes. The major new feature in this build is a low-level change to the Memory Manager. When memory pressure is detected, compression is used to attempt to alleviate this pressure, thereby relegating paging to the "Last Resort" basket. The only other notable change in this build is the return of color to window title bars. This functionality does have limits, though. If an app uses a custom title bar (Win32 API) or sets the title bar color itself (UWP/WinRT), then the system title bar color is not used.
