Ten minutes, start to finish. These steps work identically on Windows 10; only the window styling differs.
Step 1 — Close your browser
Files that are locked by a running program get skipped, and your browser is holding the biggest cache on the machine. Close it before you start.
Step 2 — Open BleachBit
Launch it normally for user-level cleaning. Right-click and choose Run as administrator only if you want Windows update leftovers and system logs included.
Step 3 — Choose a small selection
Under your browser, check Cache and, if you do not mind signing in again, Cookies and Session. Under System, check Temporary files, Recycle bin, Thumbnails and Logs. That is enough for a first run.
Step 4 — Press Preview
A list appears: every file that would be removed, plus a total at the bottom. This is the moment to notice anything unexpected. Nothing has been deleted yet.
Step 5 — Press Delete
Confirm, and the cleanup runs — usually a few seconds, longer if you checked thumbnails on a machine with a large photo library. A completion log tells you how many files went and how much space came back.
Step 6 — Restart your browser
The first page load will be slightly slower because the cache is empty. That is normal and it refills as you browse.
Typical results
A PC cleaned for the first time in a year commonly gives back one to five gigabytes. Heavy video streaming and large browser profiles push that higher. If you were expecting more, the disk space guide covers the bigger targets that no cleanup tool touches.
Two mistakes to avoid
- Checking every box because more looks better — read descriptions instead,
- Skipping Preview. It costs seconds and prevents every regret we hear about.
