Windows 10 build 10525

Windows 10 build 10525 is the first officially released Insider Preview build and the earliest available build of Windows 10 November Update, which was available to Windows Insiders in the Fast Ring on 18 August 2015. This build is notable to be served as a baseline for subsequent changes in Windows 10 November Update's development cycle.

New features and changes

 * 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 return of color to window title bars, given the application doesn't use a custom title bar (Win32 apps) or doesn't change title bar color via  (UWP apps).
 * Some copies of this build is reverted back to Windows 8 branding in  used since build 9821 until build 10166, instead of Windows 10 branding used in RTM build of the original release of Windows 10.
