A Windows 10 users has vision problems and wants to enable voice activation in as many applications as possible. Where can the user do this?

Voice activation, accessible in Windows Settings under Privacy, allows the user to enable microphone access and select which apps can use voice activation even while the device is locked. In Windows 11, the options are slightly different. Select Privacy & security, then Speech from the Windows Settings menu. The option is enabled by default. By entering those settings in Windows Settings, you can manage default apps for opening sorts of files such as photos or mail via the Control Panel's Default Programs app. You can give or deny applications access to your notifications in Windows Settings by selecting Privacy, then Notifications. Indexing Options in the Control Panel analyzes words in files as well as file information to give quicker file searches.
