    I’ve been exploring how Windows 8/RT stores Metro apps. Why? Partially to learn some of the stuff I’ll talk about here and partially because I like exploring how Windows works.


    Windows "Store" apps are stored where Windows keeps all programs; The Program Files folder. In there is a folder called “WindowsApps”. In this folder each app will have a folder. The folders name will also include a lot of extra information besides the apps name. It includes what platforms the app will run on (or neutral if all), the version number, and usually the publisher.




    One thing you may notice is that an app may be in there more than once, each with a different version number. The newer version includes only the files that were changed between versions. This does waste some space, though not as much as it would if it replaced the old files. Why it does this it do this? Honestly I don’t know. My guess is for roll back reasons. (Currently there is no way to roll back so I’d guess they plan to add it.) If you want to get the space back you can copy the files from the old version to the newer version, keeping the version of files in the newer version of the app. Interestingly, Microsoft seems to have started patching by merging the two folders for you as of the 11/13 Patch Tuesday. I don’t know though if it will “cleanup” after its self by merging apps that were in separate folders.


    If you're a developer I have some good news for you. First HTML5/JavaScript/CSS3 apps are NOT compiled, encrypted, or in some form modified from the original files. This means that you can open the folders up and see the source as the developer created it. XAML/C#/VB apps are a bit different, more like with Silverlight XAPs in that the XAML files are there but the code is in a DLL that could be encrypted, which is up to the developer. I would note however that the apps are protected so if you modify a file the app will crash when you try to run it, though not till the app tries using that specific file.


    If you have multiple users on your machine, there is good news for you. Windows doesn’t re-download the app for each user. Instead it just keeps one copy of the “executable” and a separate folder to store per user data (like saved games). This per user folder is located in a user’s local AppData folder under a folder called Packages. There is a folder per app there, with the same name as it has in WindowsApps (though without the version number).


    Now a personal favorite trick of mine is to use NTFS symbolic links to make Windows take better advantage of a multi drive system. “Sadly” Windows 8 seems to be smarter about them and you cannot use them as easily. Sadly this means that you cannot move Metro Apps around (to save drive space for example) or the unique user data for them (to move saved games between machines for example).


    In the end we learn one thing really; Microsoft has really thought out how Marketplace apps work. They are tamper proof and try to use as little space as possible. Good for the average user. Not so good for hackers.

    I believe it keeps the multiple versions since each user can have a different version installed. For example when I create a new account, I have to re-update Camera, Finance, Music, Photos... etc.

    I noticed this behavior after the patch, but I can't say whether the apps in question were downloaded before or after the patch. I had to update from both accounts and then the older versions went away.

    • I throw this out every once in a while.  Is anyone interested in writing up "semi-formal" reviews here on the forums?  I say semi-formal because they don't have to be pro level, just a good attempt at telling the story about the gear.  Something you have purchased lately.  You don't have to go buy stuff, just incorporate what you have already have purchased.  Hit me up with any questions.  You never know where it will lead!

    • D-Link has dropped a couple of new products and additions to their lineup of smart home gear.  Hold on because there is a lot of gear!
      Let's start with cameras.  D-Link has new Wi-Fi cameras, the Full HD Pan and Tilt Pro Wi-Fi Camera (DCS-8302LH) and Full HD Indoor and Outdoor Pro Wi-Fi Camera (DCS-8526LH).  These are not just new, and good looking cams, they can now perform people detection and glass break detection.  The new cameras also feature expanded ways for customers to save video, including ONVIF Profile S, which enables custom storage and streaming options to personal NAS devices, built-in storage microSD capacity up to 256 GB, as well as free and paid cloud storage options. 

      This year's camera models include both an indoor and an outdoor model. The outdoor model features a spotlight and siren that can be triggered when motion is detected, deterring potential intruders. The indoor model pans around to give a full 360-degree view of any room and tracks motion. Both include two-way audio. 
      Full HD Pan and Tilt Pro Wi-Fi Camera is the model (DCS-8302LH), available in Q2, 2020, and retail pricing will be $99.99.
      Full HD Indoor and Outdoor Pro Wi-Fi Camera is the model (DCS-8526LH), available in Q3, 2020, and retail pricing will be $119.99.
      One of my favorite products is Wi-Fi.  D-Link has a whole lot of new products coming including Wi-Fi 6, Mesh, Alexa and Google Assistant integration, IFTTT, Parental Controls, and more!

      There are so many new SKU's that I can't make heads or tails of them!  I'm going to be speaking with D-Link more this week and will sort all of these out. I do want you to see all they are offering and what the release date and projected retail pricing will be.

      Here is the main design.

      Below is a part of the order that I put in!  

      The Heather Grey above is the Extra Soft version and it is awesome.  I highly recommend the softness!    The "Chili Red" is the Tri-Blend and probably my favorite feel and color.

      This is the Zip-Up Hoody, Heather Indigo, Sponge Fleece, Men's, Large.  In my podcast I couldn't remember what style it was but it is Sponge Fleece. It's REALLY soft on the inside. Soft outside as well. The only problem is with the zip up hoody the logo is on the back. Regular hoody, it will be on the front.

    • OneDrive Personal Vault and expandable storage
      Microsoft's OneDrive has a few new features and options worth pointing out.  Personal Vault and Expandable Storage.
      Personal Vault is a protected area in OneDrive that can only be accessed with a strong authentication method or a second step of identity verification, such as your fingerprint, face, PIN, or a code sent to you via email or SMS. 
      Personal Vault gives you an added layer of protection for your most important files, photos, and videos—for example, copies of documents such as your passport, driver’s license, or insurance information—should someone gain access to your account or device.
      Plus, this added security won’t slow you down. You can quickly access your important documents, photos, and files with confidence wherever you are, on your PC, OneDrive.com, or your mobile device.

      Beyond a second layer of identity verification, Personal Vault also includes the following security measures:
      Scan and shoot—Using the OneDrive app, you can scan documents or shoot photos directly into your Personal Vault, keeping them off less secure areas of your device, like your camera roll.
      Automatic locking—No need to worry about whether you left your Personal Vault or your files open—both will close and lock automatically after a period of inactivity.
      BitLocker encryption—On Windows 10 PCs, OneDrive automatically syncs your Personal Vault files to a BitLocker-encrypted area of your local hard drive.
      Restricted sharing—To prevent accidental sharing, files in Personal Vault and shared items moved into Personal Vault cannot be shared.
      Taken together, these security measures help ensure that Personal Vault files are not stored unprotected on your PC, and your files have additional protection, even if your Windows 10 PC or mobile device is lost, stolen, or someone gains access to it or to your account.
      Expandable Storage
      If you are and Office 365 Subscriber you get 1 TB of OneDrive storage space with all the other Office goodies like Word, Excel, etc.  I know personally that I have gone over the 1TB limit and have always wanted to be able to add additional storage to my account.  Now you can!

      Pick and option and keep on hoarding, errr, I mean saving! Cancel anytime, upgrade at any moment.
