01 · Credit where due
Where CCleaner is the right choice.
CCleaner has fifteen-plus years of history and cleans junk across a long list of applications in one batch run. If what you want is a familiar one-button cleaner and you are comfortable with batch changes, it does that job.

Explained, measured, revertible.
-
01 · Explained, not batched
Each change explained, effect stated first.
CCleaner applies a batch cleanup. Tempered proposes each change with the expected effect in plain language, and waits for your approval.
-
02 · No registry cleaning
Tempered refuses the registry-cleaner claim.
CCleaner ships a registry cleaner. Tempered does not use registry cleaning as a performance claim at all — registry writes happen only for documented tweaks and startup toggles, each logged and revertible.

03 · Undo Center
Every settings change leaves a route back.
Each Tempered change lands in a ledger. Settings changes get per-item revert and revert-all; one-way actions are logged as one-way. Each entry records the old value and the new one. There is no health score.

04 · AI advisor
Ask what is slow in plain language.
Tempered reads the live system and answers with a finding tied to a reviewable action. We have not found an equivalent in CCleaner.
03 · Price
CCleaner Professional vs a free core app.
CCleaner Professional is listed at about $44.95 a year. Tempered's core app is free — the paid tiers cover most of the AI work and the deeper tools: Torque is $5.99 a month billed annually ($7.99 month-to-month) for every deep scan, the Task Manager, and the Developer Hub.
If a free tool does what you need, use it — Tempered's free tier is the full core app, so the comparison costs nothing to run yourself.
