HKLM\Software\Policies\Microsoft\Edge
OBSOLETE: This policy is obsolete and doesn't work after Microsoft Edge 125. This policy is obsoleted because Math Solver is deprecated from Edge. This policy won't work in Microsoft Edge version 126. This policy lets you manage whether users can use the Math Solver tool in Microsoft Edge or not. If you enable or don't configure the policy, then a user can take a snip of the Math problem and get the solution including a step-by-step explanation of the solution in a Microsoft Edge side pane. If you disable the policy, then the Math Solver tool will be disabled and users will not be able to use it. Note: Setting the 'ComponentUpdatesEnabled' (Enable component updates in Microsoft Edge) policy to disabled will also disable the Math Solver component.
