Changes[edit | edit source]

Login process[edit | edit source]

This build's login process has been updated to boot up faster when compared to previous builds, although this breaks safe mode in the process.

Services[edit | edit source]

The Discovery Persistence Service has been introduced. Human Interface Device Access has also been renamed to HID Input Service.

Bugs and quirks[edit | edit source]

Installation[edit | edit source]

Most copies of this build's installation media are not bootable due to corruption.

Desktop Compositing Engine[edit | edit source]

While the Desktop Compositing Engine functions correctly, Direct3D shaders are not enabled due to a bug. As the DCE window frames rely on these shaders to function, it is not possible to enable them in this build.

Safe mode[edit | edit source]

By default, it is not possible to login while in Safe mode. Due to the login process change, the "User Profiles Service" and "Group Policy Service" are required to access the login page and perform the login process respectively. Because these services are not configured by default to start within Safe mode, this results in logonui.exe showing the error "There are no more endpoints available from the endpoint mapper" on the login screen and failing to show available user accounts.

These services can be enabled to function in safe mode by adding the following entries to the service whitelists in the registry:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\ProfSvc]
@="Service"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\GPSvc]
@="Service"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot\Network\ProfSvc]
@="Service"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot\Network\GPSvc]
@="Service"
