Windows 8 apps for engineers

Your downloaded apps will be associated with your Microsoft account , so you'll only have to purchase apps once. You can try certain apps for a limited time before deciding to purchase them. Just click the Try button when available to download a demo of the app. You may find some apps in the store that are designed to work only in the Desktop view.

After navigating to the app information page, click Go to publisher's website and then follow the instructions to download and install the app. Apps may periodically receive updates , which can help keep them running smoothly and even add features.

If updates are available for any of your apps, a link for Updates will appear in the top-right corner of the store. You may also notice available updates from the Start screen if the Store tile is active as a live tile.

Windows 8: Downloading Apps from the Windows Store. Opening the Store. Categories in the Windows Store. Navigating to categories in the Store. There's still plenty of time to plug these holes but we definitely need to keep a fire up their ass to make sure our apps aren't cracked in one fell swoop. If I'm relying on your app store and one point of failure is all that is needed to expose EVERY app, you might want to rethink your design a bit and I hope they at least give us the option to run extra licensing mechanisms on top if we so choose.

If they don't plug these holes AND get heavy handed there, I could never recommend developing for their app store. Philippe Da Silva Says: With every new OS comes new security threats especially when you're adding something new that hasn't been tested accross mainstream audience. While I don't care much about seeing people modifying apps I purchase since it opens the way to application "mods" that us, consumers, will decide to use or not, I'm way more worried about the Win8 Apps being a real system security threat for viruses and other malware that could act on my behalf in my machine.

This should definitivelly be the top security priority of Microsoft from my point of view. I can't think of any application that would make use of the Metro UI and paradigm that don't fall into such user requirements. The signing mechanism covers everything in the package, and is independent of file type. You could even put binary files with a format of your own devising in there and it'd still be able to check their validity.

Logically speaking, it's pretty similar to how Silverlight supports it - you sign the container rather than individual files. In Silverlight, you can apply a digital signature to the ZIP file, and that'll cover everything in there, no matter what the format of the individual files. The fact that the streams happen to be extracted out into files in a folder in Win8 is no obstacle to this - it just requires a scheme for how the whole directory should be handled - as long as Win8 knows that say the appx manifest contains a list of signatures for everything including itself , then it can check everything.

IIRC, that's pretty much how ClickOnce worked - it was able to check validity even when each of the resources in the app was downloaded separately. So this is not new. Nor is reverse engineering. ZUyq5def Says: Maliscious won't have access to the program filesapplications directory among other things, such as signing. The steps that Justin goes through to access the directory require explicit user action - they can't be done programmatically unless the app already has privileges - in which case it doesn't really make sense for the app to go messing w other apps, because it can already do whatever the maliscious user wants.

However many viruses, spyware and malware if not the majority of those currently use those locations to hide, store and modify their executables.

Theoretically, you're right to say there's a hurdle here. Practically, you'll have to ignore the entire history of modern-day malware to claim it'll matter in the long run. Second of all, it doesnt matter if the code is plain text,. Even in c code, you just disassemble the binary and its right there in front of you. You can do the same things you are doing now with html. On an open system like a PC, its impossible to stop this.

Its just the reality of software development. If you make good software, it will be pirated. And those that pirate will never buy your stuff in the first place anyways. Zach Heise Says: Hi Justin, I was curious about this in the Customer Preview released yesterday, so I found your blog entry by searching for "windows 8 programs file tree location" and got here. It looks as if in this version, c:program filesapplications no longer exists.

Where could all of these newly-available "store-bought" free apps be living now that they're downloaded? I hate all this handholding Metro does. For actual work, it's useless. Zach Heise Says: Nevermind, found it! You probably already knew that though! Vamshi Says: Wow thats a great find! Alex Says: Excellent article! I'm looking forward to your next article concerning apps. On Windows 8 all the important code will be right there for people to steal.

Think before you post next time. Kapil Says: Now folder name is WindowsApps It has been moved somewhere else. Any idea where these apps can now be found? Brandon Says: How can one change the default install path for apps?

I really don't want all these apps eating up my small SSD drive! Alex Says: Seeing that you can change certain thing in the folder, is there any way to launch desktop applications, while preserving image subway tile, only shifting toward openness. Exe or link? JuanK Says: This is not a microsoft problem, is allsoftware engineering problem. Decompile managed code is more dificult than just edit a javascript, but still being an easy task.

Kept in moder times. Times when you assume that compile aan app will secure your code is far far away in the past. If you want to modify any application behavior, just need to known what platform is and make the changes. How you think 'hackers' crack Adobe products one release after other, just few days or hour before program availability?

Current world is not easy. You want to protect your algorithms or logic? Legal terms, agreements etc are the final protections. Sure, you need to protect your application in any way, obfusctate code, use in memory secure strings for sensitive data, encription in any complexity levels etc, thats necesary because for more protections you use, less 'young ' people with lots of free time will success breaking your secure barriers.
