If Windows Search just isn’t cutting it for helping you find your files, you can give it a little help by adding tags to many file types, from images in JPEG and PNG format to Office documents in DOCX, XLSX, and PPTX format.
Tags work more or less like they do in any other system—photo libraries, social networks, et cetera. Unfortunately, there’s no way for Windows to auto-generate tags by itself. You’ll have to add and manage them manually. Then again, that might be a plus, depending on your personal style of organisation.
