== New features and changes ==
*The File History feature, originally known as History Vault, has been introduced in this build.
*The modern setup client first introduced in build 7796 now includes a progress bar and has the ability to go online to check for updates.
* The This copy of Windows is not genuine watermark no longer appears on the desktop.
== Redpill ==
=== Immersive features ===
*The Start screen tiles are now colored, and the Metro Horizon has been removed, although its resources are still present in twinui.dll.
*Right-clicking on a tile now shows a menu with several options.
*Pattern logon is available after setting EnablePatternLogonForInternalTesting in HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion to 1, however there's no option to use it on the login screen.
* A new OOBE has been introduced.
* A new AutoPlay dialog has been added, which is just the exact same as Windows 7 but larger.
== Bugs and quirks ==
=== General ===
* Shutdown or restart will cause a softlock when running this build in VMware Workstation 15 or newer. This can be worked around by using the host's Power menu.
* Running this build in VirtualBox with the Hyper-V paravirtualization interface enabled will result in a bugcheck.
* Certain visual elements in select MMC snap-ins (such as Services) may use the Wingdings font.
*The name of the floppy disk drive driver remains in pseudo-language.
=== Setup ===
* The last word of status messages shown when starting Setup and before the computer reboots into OOBE is cut off.
* Attempting to select a network type will result in a driver unload bugcheck. To work around this issue, remove or disable any network adapters before booting into OOBE.
=== Shell ===
* Enabling Redpill after upgrading from build 7875 will cause Windows Explorer to not respond when trying to load the Start screen and enter a crash loop. Using Redlock option 2 instead will enable Redpill features excluding the Start screen.
* An unassigned file association error may occur if certain options in the Start tile drop-down menu are selected.
* Changing personalization options may occasionally crash File Explorer. This is caused by InputSwitch.dll and can be fixed by replacing the file with a copy from build 7875.
* The new language bar is mostly broken in this build and only works on rare occasions. It may occasionally spawn an empty, non-functional button between the notification area and the current date/time.
=== Themes ===
* The title bar and watermark use the Arial font due to mistyping in the aero.msstyles and aerolite.msstyles files.
* Only the top portion of the window frame is blurred when using the Windows Aero theme, leaving the side borders transparent.
* The Windows Basic and the High Contrast themes do not render properly due to the enforcement of the DWM Aero theme.
