A dev machine you can reason about. Every change explains itself.
Startup, services, and scheduled tasks in one view, DNS chosen by measurement, and removals that clean up after themselves. No unexplained registry surgery.
Free · Windows 10 and 11
The problem.
You run the same build twice and get two different numbers, and the difference is whatever Windows decided to do in the background between runs. The usual fix is a debloat script that disables dozens of services without saying why, which swaps a noisy machine for an unexplained one.
Dev machines collect entropy. An agent from every tool you ever evaluated, services left behind by SDKs you removed a year ago, and whatever the last debloat script did that nobody wrote down. The instinct to strip that back is right. The scripts are the problem, because a change you cannot explain is a change you cannot trust when something breaks three weeks later.
eclean treats every change like something you should be able to defend in review. Recommendations describe what they change and why before you apply them, and Optimizer keeps a history so supported changes can be reverted from the same place you enabled them. Removals look for the files and registry entries left behind, so uninstalled means uninstalled. Nothing happens to the machine that was not explained first.
Run-to-run variance is mostly other people's code. Between two builds, Windows may index files, sync something, wake a scheduled task, or let a background app help itself to a core, and the second number moves for reasons that have nothing to do with your change. You cannot eliminate that noise entirely, but you can enumerate it. Booster's single list of startup entries, services, and scheduled tasks is the enumeration, and everything on it is something you can name, keep, or cut.
The tweaks listed below are the ones a build machine actually feels. Stopping background apps and letting the scheduler favor the foreground window keep interactive work responsive under load. The service host tweak regroups Windows services into fewer processes, trading a little isolation for noticeably less resident memory, and it says exactly that before you apply it. Nothing here is a mystery script, and every applied change sits in a history you can diff against your memory of the machine.
The same standard applies to what eclean refuses to do. There is no registry cleaner, because deleting registry keys for speed is folklore with a blast radius. The boundary also runs around your toolchain, your containers, and WSL, which belong to you and your dotfiles rather than to a system utility. eclean manages the Windows underneath, keeps its receipts, and leaves the parts you have already automated alone.
What eclean does here.
Background work, enumerated
Booster puts startup apps, services, and scheduled tasks in one list, so the load behind a build or a benchmark is something you decided on. DNS is chosen from response times measured on your own connection, and Automatic DNS, in Pro, re-checks it every week.
Pro covers 2 PCs. Family covers 5.

Removals that clean up after themselves
Standard uninstalls often leave files and registry entries behind. Uninstaller looks for what remains after removal, so retired SDKs and tools you evaluated once are actually gone. Quiet uninstall, part of Pro, skips the screens of uninstallers eclean recognizes.

The full inventory in plain terms
Windows version and build, firmware, processor, graphics, memory, storage, and network details in one place, with focused live views for the moments a machine behaves in a way its specs do not explain.

Disable Background Apps
Prevents apps from running in the background when not actively in use. This reduces CPU and memory usage, extends battery life on laptops, and improves overall system responsiveness.
Disable Svchost Splitting
Combines Windows services into fewer svchost.exe processes instead of running each separately. This can significantly reduce RAM usage, though it slightly decreases service isolation.
Limit Windows Search to Local Results
Keeps Windows Search focused on local results by turning off Bing web search, cloud results, and search suggestions. Local file search still works as normal.
Prioritize Foreground Apps
Configures Windows process scheduling to give higher priority to the active window. This improves UI responsiveness, reduces input lag in games, and provides a smoother multitasking experience.
Every tweak above changes Windows settings, and applied changes land in a history. See how Optimizer works

Where eclean stops
eclean manages Windows. It does not touch your toolchain, your containers, or WSL.
It promises no benchmark numbers. A quieter, better-explained background is the claim.

Still deciding? Fair questions, answered.
Why is there no registry cleaner?
On purpose. Registry cleaning has not delivered measurable speed on any Windows since XP, and the category keeps shipping it because a scary count of issues sells scans. eclean only ships changes whose effect you can see and verify.
Is eclean safe to download?
Yes. The installer is a single signed file from our own release server, with no bundled extras. While our signing certificate is new, Windows SmartScreen may ask you to confirm the publisher, which reads eclean Labs AB, the company that signs our Windows installer. What the app collects, and what it never touches, is documented in the trust center.
Is the free version actually useful?
Yes. The core of eclean, understanding your PC and keeping it tidy, is free without time limits or nagging. Pro adds the upkeep that runs on its own, like weekly cleanup.
