Windows keeps a track of your recently or frequently accessed files and displays their list in the File Explorer’s Quick Access, Start Menu’s Recommended section and the Taskbar Jump Lists. This feature makes it easier to access a file directly without the need to navigate to its folder location. 

Folder Options, lets you change the settings or set preferences for the File Manager in Windows computers. You can hide/unhide folders, set thumbnail view for files and disable or enable recently accessed files history in Quick Access using the Folder Options dialog. 

Caps Lock and Num Lock keys on most keyboards have physical LED indicators for showing their active status. However, some laptops, wireless and non-backlit keyboards may not have these physical indicator lights.

Windows maintains a thumbnail database for media files like photos and videos and certain documents like PDF, word documents or powerpoint presentations.
