You can find the requirements for Chromebooks here: [Setting requirements Google Workspace](/en/article/setting-requirements-for-google-workspace-bu42y/). You can find the requirements for Windows laptops here: [Setting requirements Microsoft Intune](/en/article/setting-requirements-for-microsoft-intune-e9d6y5/) With the following steps you can check whether your students' laptops meet the requirements for Myndr to work properly: ### 1. Only sign in with a school account ###### Chromebooks On a Chromebook, try this with a private Google account. ([If you don't have a Google account, you can find out here how to create one for free](https://support.google.com/mail/answer/56256?hl=nl).) If you cannot sign in, this setting is correct. If you can sign in, contact your IT service provider to have this turned off. ###### Windows laptops On Windows laptops, check whether students can add private accounts themselves. Sign in to a student laptop with a student account and go to Settings > Accounts > Other users and check whether you can add an account there. If you cannot add an account, this setting is correct. If you can add an account, contact your IT service provider to have this turned off. ### 2. Do not allow opening Incognito/InPrivate windows ###### Chromebooks Sign in to a Chromebook with a student account. Open the browser, click the three dots and click New Incognito window. If the option is not available and an incognito window cannot be opened, this setting is correct. If you can open an incognito window, contact your IT service provider to have this turned off. ###### Windows laptops Sign in to a Windows laptop with a student account. Open the Edge browser, click the three dots and click New InPrivate window. If the option is not available and an InPrivate window cannot be opened, this setting is correct. If you can open an InPrivate window, contact your IT service provider to have this turned off. Now open the Chrome browser if it is installed. Click the three dots and click New Incognito window. If the option is not available and an incognito window cannot be opened, this setting is correct. If you can open an incognito window, contact your IT service provider to have this turned off. ### 3a. Do not let students install apps themselves ###### Chromebooks Sign in to a Chromebook with a student account. Open the browser and go to the Google Play Store at [play.google.com](https://play.google.com). Search for "angry birds" and try to install and play the free game. If you cannot install and play the game, the setting is correct. If you can install and play the game, contact your IT service provider to have this turned off. ###### Windows laptops Sign in to a Windows laptop with a student account. Open Edge and go to [https://www.opera.com/browsers/portable](https://www.opera.com/browsers/portable), download the browser and try to start it. If you cannot use it, the setting is correct; check the next step. If you can open it AND use it, contact your IT service provider to have this turned off. Click in the search box at the bottom of the screen. Type "store". You now see the Microsoft Store; click the Microsoft Store icon. Once it has opened, click in the search field at the top of the Microsoft Store window and type "angry birds". Hover your mouse over the first result found. A "Get" button appears; click it. If you cannot click it or if the app is not downloaded, the setting is correct. If you can click it and the app is downloaded and installed, contact your IT service provider to have this turned off. ### 3b. Do not let students install extensions themselves ###### Chromebooks Sign in to a Chromebook with a student account. Open the browser and go to the Chrome Web Store at [chromewebstore.google.com](https://chromewebstore.google.com) and search for "sniper gun". Click the top result, click "Add to Chrome" and click "Add extension". If you cannot add the extension, the setting is correct. If you can add the extension and play the game, contact your IT service provider to have this turned off. ###### Windows laptops Sign in to a Windows laptop with a student account. Open Edge and go to [https://microsoftedge.microsoft.com/addons/Microsoft-Edge-Extensions-Home](https://microsoftedge.microsoft.com/addons/Microsoft-Edge-Extensions-Home) and search for "sniper gun". Click "Get" at the top result and then "Add extension". If you cannot add the extension, the setting is correct. If you can add the extension and play the game, contact your IT service provider to have this turned off. Now open Chrome if it is installed and go to the Chrome Web Store at [chromewebstore.google.com](https://chromewebstore.google.com) and search for "sniper gun". Click the top result, click "Add to Chrome" and click "Add extension". If you cannot add the extension, the setting is correct. If you can add the extension and play the game, contact your IT service provider to have this turned off. ### 4. Disable Copilot (Windows only) Sign in to a Windows laptop with a student account. Open Edge and click the coloured Copilot icon at the top right of the browser. If this icon is not there or you cannot open the sidebar, this part of the setting is correct. If you can open Copilot, contact your IT service provider to have this turned off. ### 5. Disable the Sidebar (Windows only) Sign in to a Windows laptop with a student account. Open Edge and go to [https://www.microsoft.com/nl-nl/edge/features/sidebar](https://www.microsoft.com/nl-nl/edge/features/sidebar). Scroll down a little to the "Tips and tricks" section and, at "Play games from the sidebar", click "Try it now". If nothing happens, the setting is correct. If the Sidebar opens on the right, contact your IT service provider to have this turned off. ### 6. Check that the right Myndr extension is installed Sign in to a student device and go to [test.myndr.net](https://test.myndr.net) in every available browser. The page shows whether the Myndr extension is installed and which variant. If the variant does not match what you requested, contact us.
