New features and changes[edit | edit source]

Start[edit | edit source]

Start button[edit | edit source]

This is the first available build to re-implement the Start button, which had been absent since Windows 8 build 8186. Behavior at this stage in development is largely identical to the Start screen thumbnail included as part of the initial Windows 8 release, which requires the user to mouse over to the bottom left corner of the screen to display.

Shutdown options have been added to the ⊞Win+X drop-down menu.

Start screen[edit | edit source]

Pinned apps and groups can be moved without needing to go into "Customize" mode.
Resize options for pinned apps have been condensed into a context menu.
Several wallpaper options have been removed.

Apps list[edit | edit source]

The apps list can now be sorted into categories.
Tiles for desktop applications now use the icon's dominant color; a feature first introduced as part of Windows 8 build 7878 but later removed in late Milestone 3 builds.
The PC Settings app is now displayed on the apps list and can now be pinned on the start screen again, after being absent in Windows 8 build 8220.
The appearance of the search box has been updated.

Search[edit | edit source]

⊞Win+S can now be used to open the search charm.
Filtering options have been re-added and can be enabled from a drop-down.
The search results page has been updated.

File Explorer will now open to This PC instead of Libraries.

Internet Explorer[edit | edit source]

Internet Explorer 11 now recognizes itself as a preview build.
The copyright date has been updated to 2013.
The option to disable tabs has been removed.

The Work Folders applet has been added.

PC Settings[edit | edit source]

A new home page has been implemented.
The user's accent color is now used on the selection pane.
The search box has been moved to the selection pane and has been condensed into an icon.

Bugs and quirks[edit | edit source]

OOBE[edit | edit source]

This build has a broken OOBE and you may have to make an account manually and skip OOBE by making changes in the registry.

To skip the OOBE and go to the desktop immediately, you can follow these steps:

First solution:

1. After installing, boot into Windows Setup.

2. Press ⇧ Shift+F10 to open Command Prompt, and then open Registry Editor.

3. Load the following hives to the registry: (Generally the system drive is located at D:\)

(System drive):\Windows\System32\config\SAM

(System drive):\Windows\System32\config\SOFTWARE

(System drive):\Windows\System32\config\SYSTEM

4. Navigate to HKEY_USERS\SAM\SAM\Domains\Account\Users\000001F4 and then modify the number "11" in "F" to "10".

5. Navigate to HKEY_USERS\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon and then modify ""EnableFirstLogonAnimation"" to 0.

6. Navigate to HKEY_USERS\SYSTEM\Setup and then modify these below:

CmdLine =

OOBEInProgress = 0

SetupPhase = 0

SetupType = 0

7. Unload the hives that you loaded before, and then restart.

Sometimes the account has a password. Run the net user command to reset the password if it happens.

Second solution:

1. On the first screen of OOBE, press ⇧ Shift+F10, a command prompt will appear.

2. Enter the regedit command, then you will open the Registry Editor.

3. Go to the following path: \HKEY_LOCAL_MACHINE\SYSTEM\Setup.

4. Change the value of the CmdLine parameter from oobe/windeploy.exe to cmd.exe.

5. Change the value of the OOBEInProgress parameter from 1 to 0.

6. Change the value of the SetupPhase parameter from 4 to 1.

7. Change the value of the SetupType parameter from 2 to 1.

8. Close Registry Editor and at the command prompt type the following command: shutdown /r /t 00 to reboot.

9. Now, if you did everything right, when you boot, you should automatically have a command line. You need to manually create an administrator account. To do this, run the following command:

net user Administrator /active:yes

10. After that, launch the Task Manager. To do this, in the command line, enter the taskmgr command. Then end the winlogon.exe process. Or enter the following command in the command prompt:
