About Partial Trust ApplicationsFor the best privacy and security, look for partial trust applications, typically found in the Microsoft Store. The baseline configuration for partial trust applications means that they:
This is technologically enforced by the system (backed by a Windows security boundary). This can be better for privacy than using a web site, because web sites inherently have Internet access, and opting out of Internet access means your data can’t leave your device. You can identity partial trust applications in the Microsoft Store by looking at the “This app can” section and the absence of the entry “Uses all system resources” — be sure to expand the “Show more” link if it appears. If there is no “This app can” section at all, then the application doesn’t require any permissions, which is the theoretical best possible scenario. (If it does disclose “Uses all system resources”, that is a full trust application; for more information, see the “Sidebar: About Full Trust Applications” section.) Producing or Scanning QR Codes with QRCode HelperConsider using QRCode Helper [sic] (Microsoft Store listing), which runs with the fewest permissions (none), is freely available, and can produce or scan (still image only) QR codes. If you aren’t at a Windows device or the direct link is missing, visit QRCode Helper in the Microsoft Store on the Web. Before installing, please verify that its “This app can” section is still absent from its Store listing. To produce a QR code for plain text and URLs, enter it in the text box, then click the save button. To scan a QR code using a camera, use the open file picker and look for “Camera” in the navigation pane at the bottom, then take a still image photograph with the on-screen shutter button and then click the file picker’s Open button. If this is missing, install Windows Camera from the Microsoft Store or visit Windows Camera in the Microsoft Store on the Web. For users using a non-visual user interface, note that QRCode Helper is not localized into English, and buttons are unlabeled — it contains a text box with the payload, a text box for the image dimensions, a save file button, an open file button, and a clipboard paste button (text or image file). Scanning QR Codes with QR Scanner PlusFor live scanning of QR codes from the camera, consider using QR Scanner Plus (Microsoft Store listing), which runs with the fewest permissions (camera), is freely available, and can scan QR codes. If you aren’t at a Windows device or the direct link is missing, visit QR Scanner Plus in the Microsoft Store on the Web. Before installing, please verify that its “This app can” section still only contains “Use your webcam” in its Store listing. When the QR code is detected, its URL appears in the center bottom. Click the menu icon at the bottom to review scan history, and to export the content to a CSV file for copying. Click an individual URL entry for an option to open it in a web browser. The alleged Copy and Delete context menu depicted in the Store screenshots seems to be absent in this version, or is inaccessible using mouse or keyboard. For users using a non-visual user interface, note that some buttons are unlabeled — those buttons correspond to the clipboard (copy or paste depending on mode) and a save file button (create mode only). Alternative ProductsQR Notes (Microsoft Store listing) (or visit QR Notes in the Microsoft Store on the Web) runs with minimal permissions (camera; contacts for saving scanned information), is freely available, and can produce or scan (front / back camera or file) QR codes. Before installing, please verify that its “This app can” section still only contains “Use your webcam” and “Use your contacts” in its Store listing. Its feature set is more sophisticated, so the learning curve is higher. You are responsible for adding the quiet zone margin as described in the Publishing QR Codes section. You might find it frustrating that a scanned hyperlink can’t be copied to the clipboard or directly edited. ScreenCode (Microsoft Store listing) (or visit ScreenCode in the Microsoft Store on the Web) runs with the fewest permissions (none), is freely available, and can produce or scan (screenshot or clipboard image) QR codes. Before installing, please verify that its “This app can” section is still absent from its Store listing. You are responsible for adding the quiet zone margin as described in the Publishing QR Codes section. You might find it frustrating that it is dependent on the clipboard or Snipping Tool, and saving to a file seems nonfunctional. When evaluating the “This app can” permissions for a Microsoft Store product, here are some common permissions you might see:
If you cannot install software or access the Internet, 3D Builder may be preinstalled. To produce a QR code, create a New scene, Insert a Cube, then Paint a Texture choosing to generate a QR texture for your payload without a transparent background and position it on the cube, and finally adjust the camera position and take a screenshot or Print on paper. Publishing QR CodesPlease ensure your usage of QR codes complies with licensing rules and regional patents. For the latest licensing guidance, see the QR Code FAQ, particularly “It is [sic] all right to use QR Codes with colors or an inserted illustration?” (these features are absent from the specification, and therefore in breach of the license). Additionally, note that the “quiet zone” margin of 4 rows / columns on each side is part of the specification, so if you crop it out from the image file (or if the application neglects to include it), ensure that your design includes an equivalent margin. If your QR code is going to be directly uploaded as an image file or embedded in an electronic document, and depending on the application that you use to save the image file, consider saving the final copy to a new file instead of overwriting an existing file. A common oversight in applications is neglecting to trim or reset the file size when overwriting a file, leaving leftover content from past versions at the end of the file if the newer version is smaller than the original version, which is an information disclosure concern and prevents the excess storage space from being freed. Saving to a new file sidesteps this oversight. Sidebar: About Full Trust ApplicationsFull trust applications, including loose Only install and use these full trust applications if you fully trust the publisher and developers, as there is no technological enforcement, only social enforcement. To put this into perspective, consider applying your standard interview process to those people, because you are granting them unattended access to your device and account (as if you had left your desktop unlocked and given your PC to them to borrow).
