Health Check shows your PC health score and finds junk files you can remove. Follow the steps below.
Step 1: Open Health Check in the left sidebar. Review the Health Advisor score and the “What we found” list, then click Scan Now to scan for junk.
Step 2: When the scan finishes, review categories under Scan Results (System, browsers, caches, and more). Use Select All or pick items you want to remove, then click Clean.
Step 3: After cleaning, check the Health Advisor again. The Junk files score should improve, and Overview shows Last Clean with how much space was freed. You can still use Fix for memory, startup, drivers, or storage.
