Windows 8 App

Windows Store

Sideloading

Custom install

The app interface

Windows apps are special

• Delivered via the App store or sideloading• Launch via dynamic Tiles• Can be placed into background• Full-screen, chromeless interface• Multiple display types and views• Touch as primary input• Are distributed via app packages (.appx)• Store apps require 1024x768• Snap view requires 1366x768

App view

Snap view

Closing an app

Uninstall an application

• Classic app• Win8 app

Apps can be build in

• JavaScript• Visual Basic• Visual C#• Visual C++

What has fundamentally changed

User launches apps

User manages app lifetime

User selects app for foreground

System manages app lifetime

App 1 App 2 App 3Running

Suspended

Terminated

… App N

Apps suspend after a short

delay

App terminated under memory

pressure without

notification

Apps resume instantly from

suspend

Exception to suspend in background

- Audio apps- Upload / download apps- Lock screen app’s

Process lifetime walkthrough

What happens during the suspend1.App gets about 5 sec to save state2.System resources focused on app user is interacting with in

the foreground3. Inactive apps have no impact on battery life or

responsiveness, they are suspended by the OS4.Enables instant switching between apps!

When do apps Terminate

1. System needs more memory2. User switch occurs3. System shutdown4. Apps crash

Apps do not get notified when they are getting terminated

8 stages of an app lifecycle

DEMO

Changing how apps are launched

App launch from Start Activate via contracts=> tile, search, share,

etc.

DEMO

vs

Splash screen during activation

• System provided Splash Screen mechanism provides consistent transition to your app• Shown while Windows launches your app• Presented during activation• Developer provides color and image in app manifest• Apps need to present a window within 15 seconds of activation or the app will be

terminated

ApplicationOptional extendedsplash screenapp controled

System controled splash screen

Application launch

DEMO

Always just user

Distribution via App Store

• You must register for a developer account• Pass certification process• Adhere to MS requirements• Free of malware• Technical compliance test

• App is then signed by MS and released to public• You create a download / purchase page

Distribution via sideloading

• Requires Enterprise edition• Target must be domain joined or via sideloading product key• GPO set to “Allow all trusted apps to install”• Apps must be signed• Install via add-appxpackage PowerShell command

The logon interface

Lock screen

Provides basic glance information

1. Time & date2. Calendar update3. Network4. Power

Computer Configuration > Administrative Templates > Control Panel > Personalization. “Do not display the lock screen.”

Start screen

1. Live Tiles = living icons “glance and go”2. PIN3. Group4. Name groups

Pin to start screen

Application PIN Directory / webpage pin

Lock / sign off / Shutdown / reset / sleep1.Shut down, Restart, and Sleep -- are confusing

2.Lock and Sign out

Two accounts, one user , one box

Microsoft Account

Local / Domain account

Why

Use Windows Store

Roam App settings

Roam User settings

Single sign on

Connected Accounts

How

Sign in each app

Link to Microsoft account

On / off / managed sync

The Group Policy is located in Computer Configuration, Windows Settings, Security Settings, Local Policies, Security Options and is called Accounts: Block Microsoft accounts.

Computer Configuration, Administrative Templates, Windows Components, Sync your settings.

Secure?

• roam data over WWAN• all user data is encrypted on the client before it is sent to the

cloud• transmitted using SSL/TLS• The most sensitive information, like your credential

information, is encrypted once based on your password and then encrypted again as it is sent across the Internet

Why

• Associate the most commonly used Windows settings with your user account, Saved settings are available on each Windows 8 PC you sign in to

• Windows 8 Metro style app settings and last-used state persist across all Windows 8 PCs linked PCs

• Website and application login credentials are automatically synced across Windows 8 linked PCs

• Automatically sign in to apps and services that use Windows Live ID for authentication

File system

Libraries

File History

Library vs folder

• A folder is a storage area on a drive, just like a real folder in a file cabinet. Windows 8 divides your computer’s hard drives into many folders to separate your many projects. For example, you store all your music in your My Music folder and your pictures in your My Pictures folder.

• A library, by contrast, is a super folder. Instead of showing the contents of a single folder, it shows the contents of several folders. For example, your Music library shows the tunes living in your My Music folder, as well as the tunes in your Public Music folder. (The Public Music folder contains music available to everyone who uses your PC.)

File History

• Previous versions to USB or network• Offline caching• Flexible time interval

Performance of history

Performance => File History, on the other hand, takes advantage of the NTFS change journal. (no need to scan whole drives and folders

File History was designed to be easily interrupted and to quickly resume. This way, File History can resume its operation, without the need to start over when a system goes into sleep mode, a user logs off, the system gets too busy and needs more CPU cycles to complete foreground operations, or the network connection is lost or saturated.

• Uses NTFS journals• Adapts depending on CPU or I/O load

Wi-Fi Direct

Wi-Fi Direct

Wi-Fi Direct offers high bandwidth wireless connectivity between your device and PCs

Wireless connection timers

Windows 7

Windows 8

Metered network

Tells the system to be conservative with bandwidth

Ex. Only downloads critical securityupdates

Wi-Fi Offloading for low power

Device offload enables Connected StandbyKeep network connected while CPU is in deepest idle state

Achieved by offloading functionality to Wi-Fi device

Wi-Fi devices support wake patterns and power-saveWake patterns used for Push Notifications

Wi-Fi driver does auto-Power Save Mode (PSM)
