Should I turn off search indexing?
If you frequently search for files, folders, and content inside those files, then it’s best to keep the Search Indexing service on. If you keep it off, it will take much longer than usual, as Windows will search in real-time instead of using the cache. However, if that is not your use case, and the service makes your PC slow, you can turn it off.
What is the purpose of indexing in Windows?
Indexing in Windows is like creating a table of contents for all the files and folders on your computer. It makes it easier and faster for the computer to find the files you are searching for instead of searching through every file and folder on your computer. Think of it like a phone book; it’s faster to look for a name in the phonebook than calling everyone in the city asking if they are the person you are looking for.
