My Windows 10 search is slow after a recent update. How can I verify and re-enable full indexing?

Go to 'Settings' > 'Search' > 'Searching Windows'. Under 'Find my files', select 'Enhanced' to index all files and folders on your drives. Then, go to 'Control Panel' > 'Indexing Options' and click 'Rebuild' to ensure the index is comprehensive and up-to-date.
