Microsoft’s series of Windows operating systems represents some of the most commonly encountered technologies in the field of digital forensics. It is then fair to say that Microsoft’s design decisions greatly affect forensic efforts. Because of this, it is exceptionally important for the forensics community to keep abreast of new developments in the Windows product line. With each new release, the Windows operating system may present investigators with significant new artifacts to explore. Described by some as the heart of the Windows operating system, the Windows registry has been proven to contain many of these forensically interesting artifacts. Given the weight of Microsoft’s influence on digital forensics and the role of the registry within Windows operating systems, this thesis delves into the Windows 8 registry in the hopes of developing new Windows forensics utilities.

Som en effekt av att Video On Demand (VOD) är på stark tillväxt vill June, som en leverantör av mjukvara för TV-branschen, förvärva kunskaper och utvärdera Windows 8 applikationer som plattform för en VOD-tjänst. June har sedan tidigare en webblösning för VOD och vill nu även jämföra och utvärdera bland annat kunskapskrav, tidsåtgång samt fördelar och nackdelar med en Windows 8 applikation ställt mot denna webblösning. Målen med examensarbetet kan delas in i tre delar; en där komplexitet och arbetsinsats vid Windows 8 applikationsutveckling utvärderas, en där verktygen som krävs för att utveckla en VOD-applikation utvärderas och sist att implementera en Windows 8 applikation för VOD. En Windows 8 applikation utvecklades och valda lösningsmetoder dokumenterades. Dokumentation och kunskap som förvärvats under utvecklingsfasen stod sedan som grund för de analyserande och utvärderande målen. Resultatet är en Windows 8 applikation som uppfyller de mål som satts upp för programmeringsdelen samt en analys och utvärdering som svarar mot målen för analysdelen.  Ämnen som är centrala genom rapporten är Microsoft, WinRT, VOD, Smooth Streaming, PlayReady, Windows 8 applikationsutveckling samt data caching och utveckling av användargränsnitt i Windows 8. / As an effect of Video On Demand (VOD)-usage growing fast June, as a software provider for the television industry, wants to acquire skills and evaluate Windows 8 applications as a platform for VOD services. June already delivers a web-based solution for VOD and now wants a comparison and evaluation of particular knowledge required, time, complexity, data caching, advantages and disadvantages of a Windows 8 application set against this web solution. The objectives of the thesis can be divided into three parts: one in which complexity and work effort in Windows 8 application development is evaluated, one in which the tools required to develop a VOD application is evaluated and finally implementing a Windows 8 application for VOD. A Windows 8 application was developed and the selected solution methods were documented. Documentation and knowledge acquired during the development phase was then used as a basis for the analysis and evaluation objectives. The result is a Windows 8 application meeting the objectives set for the development part followed by an analysis and evaluation answering the given issues. Matters that are central through the report are Microsoft, WinRT, VOD, PlayReady, Smooth Streaming, Windows 8 application Development, data caching and interface development in Windows 8.

With Microsoft's new operating system, Windows 8, a new type of applications were introduced, Windows Store Apps. These applications must meet certain requirements in order to be uploaded to Windows own store for apps. There are also guidelines to follow. The requirements and guidelines include appearance and functionality, such as a common search function in the applications to contribute to a more unified experience. How does these requirements and guidelines influence developers? Whether the development of the Windows Store Apps gets more difficult, or perhaps even simpler, is studied and evaluated in this report. In order to reach a reliable conclusion, a Windows Store App has been designed and developed in consensus with Microsoft's requirements. The app that has been developed is intended to help users to find Stockholm's best spots. It turned out that none of the demands were unreasonable hard to implement. However, it may be difficult to find meaningful uses for some of the recommended features. If common features, such as search and sharing, are implemented it should be done in accordance with Microsoft's requirements and guidelines. This is no problem since Microsoft provides information and examples of how the features should be implemented. Of course, all of the Windows Store Apps must be able to run on all devices that can run Windows 8, which means several different resolutions and input methods to take into account. This is one of the more difficult requirements to fulfill and require extensive testing of the application, which contributes to a longer development time. With the help of Visual Studio’s simulator, it is possible to get a reasonably good idea of how the app works, but it is still not good to trust it. The look must follow the guidelines that allow the user to always be familiar with the interface, regardless of which app is running. For example, every page in the app has to be built up horizontally unlike traditional websites. The interface is easy to implement using Visual Studio’s templates but it may be really tricky if you try to implement it by yourself. Windows Store Apps is extensively different from its competitor’s apps and as a developer, you are forced to think in completely new ways. It can sometimes feel limited, but on the other hand you got very much for free considering the standard look and functionality. / Med Microsoft nya operativsystem, Windows 8, introducerades en ny typ av applikationer, Windows Store Apps. Dessa applikationer måste uppfylla vissa krav för att få laddas upp till Windows egen Store för appar. Det finns även riktlinjer att hålla sig till. Kraven och riktlinjerna innefattar utseende och funktionalitet, som till exempel en gemensam sökfunktion i applikationerna för att bidra till en mer enhetlig upplevelse. Hur påverkas utvecklare av dessa krav och riktlinjer? Huruvida utvecklingen försvåras eller kanske till och med förenklas undersöks och utvärderas i denna rapport. För att komma fram till en tillförlitlig slutsats har en egen Windows Store App konstruerats och utformats i enighet med Microsofts krav. Appen som har utvecklats är ämnad att hjälpa användarna att finna Stockholms smultronställen. Det visade sig att inget av kraven var orimliga att implementera. Däremot kan det vara svårare att finna meningsfulla användningsområden för en del av de rekommenderade funktionerna. Om vanliga funktioner, såsom sök och delning, implementeras ska detta ske enligt Microsofts krav och riktlinjer. Just detta är inga problem då Microsoft tillhandahåller information och exempel på hur det ska ske. Självklart måste alla Windows Store Apps fungera på samtliga enheter som kan köra Windows 8 vilket innebär flera olika upplösningar och inmatningsmetoder. Detta är ett av de svårare kraven att uppfylla och kräver omfattande testning av applikationen, vilket bidrar till en längre utvecklingstid. Med hjälp av Visual Studios simulator är det möjligt att få en någorlunda uppfattning om hur väl appen fungerar men den är långt ifrån att lita på. Utseendet måste följa riktlinjerna för att låta användaren hela tiden vara familjär med gränssnittet oavsett app. Exempelvis måste varje sida i appen byggas upp horisontellt till skillnad från traditionella hemsidor. Utseendet är lätt att implementera med hjälp av Visual Studios mallar men kan vara riktigt knepigt att försöka sig på själv. Windows Store Apps skiljer sig markant från konkurrenternas appar och utvecklare tvingas att tänka i helt nya banor. Det är möjligt ibland känna sig begränsad, men å andra sidan finns mycket gratis genom det standardiserade utseendet och funktionerna.

I dagsläget finns inget system som övervakar en tullstation utan att man måste vara på plats på kontoret eller stationen. Denna rapport handlar om utvecklingen av en övervaknings applikation i Windows 8 store app miljö på uppdrag av Combitech AB mot kunden Kapsch TrafficCom. Applikationen utvecklades mot en Windows 8 surfplatta för att kunna övervaka en tullstation. Användargränssnitt är utvecklat i XAML och dess logik i C#. Onion Architecture har används för att bygga upp arkitekturen i applikationen. Resultatet av examensarbetet blev en fungerande prototyp av en övervaknings applikationen till en Windows 8 surfplatta, där innehållet genereras av en simulator. Applikationen visar användaren information om en specifik tullstation, exempelvis passager och event. / Today is there no system that monitors a tolling station without the need to be at the office or the tolling station. This report concerns the development of a monitoring application to Windows 8 store app environment on behalf of Combitech AB towards the customer Kapsch TrafficCom. The application was developed for a Windows 8 tablet to monitor a tolling station. The user interface was developed in XAML and its logic in C#. Onion Architecture has been used to build the architecture for the application. The result of this thesis was a working prototype of a monitoring application for Windows 8 tablet, where the content is generated by a simulator. The application displays information for the user about a specific tolling station, for example passages and events.

Today there are many IT-systems holding information about different things. The information can for example be anything from news feeds to complex environment systems. By making these system collaborate with each other new oppurtunities and functionality can be established. However, since most of the systems are developed individually, there are different ways to communicate with each system. Therefore, The IT-agency Gaia has started a collaboration with the real estate company Klövern AB. The intention was to develop a plat- form for functional- and informational distribution focusing on commercial real estates. The platform was supposed to be available for Klöverns tenants and be used in public environments providing access to intelligent environment systems, processes in facility management and interactive information channels. This report describes the user study, the idea development and the implementation of two Windows 8 Metro application prototypes communicating through this platform. The two prototypes was directed towards the Cnema and Gaia which are both tenants of Klövern. Furthermore, both the applications was written in C# and uses ASP.Net library Signalr for real-time communication.

Projektet som denna rapport beskriver hade som målsättning att utveckla två applikationer på beställning av företaget Teknikhuset Umeå. En av dessa applikationer skulle vara till Windows 8 plattformen och den andra till Windows Phone 8 plattformen. Applikationernas syfte var att ge användaren information om högtider från kyrkoåret med hjälp av information hämtad från Svenska Kyrkans kalender API (se Henrik Johanssons rapport). Denna rapport beskriver utformandet av användargrässnitten till dessa två plattformar. Syftet med rapporten är att undersöka hur utvecklaren kan bygga ett optimalt användargränssnitt för respektive plattform och samtidigt undersöka om det finns likheter i dessa två utvecklingsprocesser. Om likheter i utvecklingsprocessen observeras så kommer dessa dokumenteras för att i framtiden kunna effektivisera utvecklingsprocessen för applikationer avsedda för dessa två plattformar. Förutom att beskriva utformandet av gränssnitten så beskriver rapporten också relevanta delar av plattformarnas respektive användargränssnitt så att läsaren kan förstå resonemanget bakom de beslut som tagits vid utformandet av användargränssnittet. Projektet resulterade i två användarvänliga användargränssnitt, ett till en Windows Phone 8 applikation och ett till en Windows 8 applikation.

Responsive design is a common expression at the web today. This thesis was about learning about responsive web design in order to apply it to Windows 8 applications created in C# and XAML. The purpose of this thesis was to learn if responsive design can be used in such applications. This was done by first learning about responsive design through a literature study about responsive web design and then specifying responsive application design. How responsive design can be used in applications was found through research and creation of an example application. No literature was found about responsive design for Windows 8 applications in C# and XAML and therefore most of the results came from own ideas and partly solutions found on different forums. The thesis was performed at Infor in Kista. The example application was a social application which was connected to a social web service developed by Infor. Responsive web design is a technique used for making webpages adapt to the size and resolution of the viewport. This is done by creating a structured, fluid layout by using a flexible grid and flexible images. Media queries are used to set up different states for presenting the page in different ways for different sizes and resolutions of the viewport. In the different states parts of the content can for example be hidden or styled. The number of columns of information can also be set to adapt to make the page easier to view. Responsive design for applications should make the layout of the application adapt to fit the application window of the device used depending on its resolution. One way to specify a responsive design for Windows 8 applications could be to create only one application which could be used on all different Windows 8 platforms, such as phones, tablets and computers. It is probably not possible today to create this one application for different Windows 8 platforms. Another way of specifying responsive design for application is to create a responsive user interface which could be shared and used in the different Windows 8 applications. The latter was the chosen definition for this thesis. The scope of this thesis was limited to only research for responsive design in Windows Store apps and Windows Phone 8 applications. Windows Phone 8 applications are applications used on smartphones with Windows Phone 8 as operating system while Windows Store applications are used on computers with Windows 8 as operating system. Other Windows 8 devices were not included in this thesis. The final conclusion of this thesis was that although it is complicated to use responsive application design it can be used for most of the user interface. A responsive user interface for the applications can be created separately, but some parts of the application pages cannot be shared between the different platforms. This results in a mostly responsive sharable user interface.

This master thesis was performed at IdaInfront AB. The aim of the thesis was toinvestigate how the design principles ofthe user interface in Windows 8 can beapplied to a case management system. Theuser interface in Windows 8 is based ona design language called Metro and it isprimarily designed for touch screens.Ida Infront AB wanted to know whatpossibilities and limitations the Metrointerface offers.The study has resulted in a prototypeapplication that is developed in Windows8. The prototype shows how the Metrointerface can be applied on a casemanagement system. Some limitations inthe usability have been identified inthe Metro interface when applied to acase management system. The mainlimitation is that it is difficult todisplay a lot of information at the sametime in Metro applications. The abilityto display a lot of information isimportant when IT systems are used tosupport decision making. The Metrointerface also offers several newfeatures that are usable for a casemanagement system, such as semanticzoom, notifications, so called tiles andbuilt in functionality of sharingcontent between applications.

This thesis analyzes current status of software distribution in gaming industry and its biggest challenges.

Practical part also includes experiment which regards to building own platform using currently existing tools and it is followed by discussion of results.

En fallstudie tillämpades för att undersöka de inbyggda apparna, Internet Explorer 10, den nya utforskaren File Explorer och reparationsverktyget ”Återställ datorn utan att ta bort filer” i Windows 8. Analysen visade att apparna E-post, Kontakter och Meddelanden sparade större delar av användarens Facebook-profil lokalt på datorns hårddisk. När bildfiler öppnades upp med appen Foton sparades miniatyrbilder av originalet på hårddisken. När videofiler spelades upp med appen Video sparades filnamnet i filer. Databasfilen index.dat som i tidigare versioner av Internet Explorer sparade webbhistorik har tagits bort och ersatts av ESE-databasen WebCacheV01.dat. Precis som föregångaren i Windows 7 sparar File Explorer både snabblistor, genvägsfiler och miniatyrbilder.  Digitala spår från det tidigare operativsystemet lämnades kvar efter reparation med ”Återställ datorn utan att ta bort filer” i foldern Windows.old.
