The following information can be used to lock down a students computer when using Microsoft Forms or any other web based Quiz or Form based activity. 

Note: When using the below steps please remember to replace the "<URL>" section with the URL of the MS Form link or other website forum option you intend to use.

Create a link using schema activation

One of the ways you can present content in a locked down manner is by embedding a URL with a specific prefix. Once users click the URL, devices will be locked down.

To enable schema activation for assessment URLs

1. Embed a link or create a desktop shortcut with:
   ms-edu-secureassessment:<URL>#enforceLockdown
2. To enable printing, screen capture, or both, use the above link and append one of these parameters:
• &enableTextSuggestions - Enables text suggestions
• &requirePrinting - Enables printing
• &enableScreenCapture - Enables screen capture
• &requirePrinting&enableScreenCapture - Enables printing and screen capture; you can use a combination of &enableTextSuggestions, &requirePrinting, and &enableScreenCapture if you want to enable more than one capability.
  If you exclude these parameters, the default behavior is disabled.
  For tests that utilizes the Windows lockdown API, which checks for running processes before locking down, remove enforceLockdown. Removing enforceLockdown will result in the app not locking down immediately, which allows you to close apps that are not allowed to run during lockdown. The test web application may lock down the device once you have closed the apps.
  Note
  The Windows 10, version 1607 legacy configuration, ms-edu-secureassessment:<URL>!enforcelockdown is still supported, but not in combination with the new parameters.
3. To enable permissive mode, do not include enforceLockdown in the schema parameters.
