Windows 10 build 10525

Windows 10 build 10525 is a build of Windows 10 November Update. This build is the first post-RTM Windows 10 build to be released by Microsoft to Windows Insiders. It was available for Windows Insiders on the Fast ring on 2015-08-18. 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. Strangely, the "About Windows" branding in this build is reverted back to the "Windows" text used in builds 9821 - 10166.

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).

Bugs and leftovers
Some copies of this build use the Windows 8 branding instead of just "Windows" branding used in builds 9821 - 10166.
