The famous single button scans and repairs everything at once. Used blind, it can log you out of every website and delete your rollback files in the same click. Set it up once, read before you repair, and it becomes the most useful button in the suite.
One-click maintenance is the feature Glary Utilities is known for, and it is genuinely convenient - once. The honest problem is what the click bundles together: several separate tools, each making its own deletions, all approved by a single press. This page breaks the bundle open so you can keep the convenience and lose the gamble.

1-Click Maintenance is not one tool - it is a bundle that fires several modules in sequence and then applies every fix they suggest: typically Registry Repair, Disk Cleanup, Shortcuts Repair, Tracks Eraser and a startup check, depending on your settings. The convenience is real. So is the trap: one click approves hundreds of individual deletions you never saw.

What should stop your finger is anything unusual: a cleanup measured in tens of gigabytes, a startup change naming your antivirus or graphics driver, or a category you do not recognise. Cancel, open that module alone, and look properly. Ninety seconds of reading is the entire difference between maintenance and roulette.

What it can delete by design are temporary files, caches, browser traces and - in some settings - the previous Windows installation files used for rollback. That is why checking the category list before the first run matters.
That is the Tracks Eraser module removing cookies. Sites keep you signed in through cookies, so erasing them signs you out everywhere and clears history too. Untick Tracks Eraser, or exclude your main browser, inside the 1-click options.
For a typical home PC, once a month is plenty. Junk files rebuild slowly, and running it daily adds risk without adding benefit. If Pro's scheduled maintenance tempts you, schedule it monthly, not daily, with the same safe settings.
