Do I need to defrag my Windows computer?

Episode 1351 (1:41:40)

Jane from Manhattan Beach, CA
Windows defrag

Jane has been told to clean up and defrag her desktop every week. Is that correct? Leo says no. It's not necessary to defrag anymore as modern operating systems take care of this on their own. Additionally, for solid state drives, defragmenting is meaningless. Jane also doesn't need to use "CCleaner" to clean up her registry either. In fact, she could make things worse by trying to clean her registry. Sure, she can delete temporary files and clear caches, but all that stuff can be done directly in Windows. The best thing to do is make sure that Windows Update is set to automatically update so she doesn't have to deal with it.
