New features and changes[edit | edit source]

The ability to select multiple wallpapers and choose to change to each one of them every selected amount of minutes has been added.
The Internet Explorer version number has been set down from 8.1 to 8.0.
- A "Suggested Sites" drop-down on the favorites bar has been added as well.
Windows Mail and Windows Calendar are no longer able to be opened, but the files for them are still present.
The ability to change the background graphics in Windows Media Player library has been removed.
The Personalization applet has been removed from the Starter SKU.
When starting Windows RE, Startup Repair now launches instead of the System Recovery Options. Startup Repair needs to be canceled to access the Recovery Options.
The notification in Windows Setup on EFI systems that an additional system partition will be created has been removed.

Bugs and quirks[edit | edit source]

Stability issues can be encountered while moving desktop gadgets.
Much like in build 6780, in some configurations it is not possible to upgrade to this build due an error in which "One or more disk volumes present were formatted in an incompatible way by a newer version of Windows".
The text under "Find out what's new in Windows" is missing, which results in displaying placeholder text.
