What PC Steward does for you
Most "PC cleaner" apps scare you with a big number and sell you a fix. PC Steward does the opposite: it shows you the evidence, explains what it means, and only touches what you approve.
See what is slowing it down
Processor, memory, background processes, storage, Windows reliability history and available hardware readings, in one clear workspace.
Every finding explained
Open any issue to see what happened, the evidence behind it, when it was observed and the exact next step. Old crashes stay history instead of dragging down today’s score.
Fixes you choose
Cleanup is limited to explained, selected categories such as old temporary files and crash dumps, and asks for confirmation first. Ordinary scans are read-only.
Find the space you need
Low-space findings show the free space you have and how much more you need, on the exact drive, so you know what to clear.
Temperatures and cooling
See supported temperature, fan and power readings, and use supported cooling controls only after you approve them.
Yours, on your PC
Runs locally on Windows 11 with no ASL account. Optional fleet views across several computers need their own setup and consent.
Yours, on your PC
What you need. Windows 11 on x64, build 22621 or newer. Sensor readings depend on your hardware and drivers; a missing reading is shown as missing, never as healthy.
What it helps you check
Review CPU and memory pressure, running processes, storage, reliability history and available hardware readings in a native Windows workspace. Findings explain the observation so you can distinguish an active problem from an older event.
What you approve
Normal diagnostics are read-only. Monitoring is off by default. Supported cleanup is limited to explained, selected categories such as aged user temporary files and crash dumps, and requires confirmation. Supported cooling controls have their own approval; hardware support varies.
What you need
Windows 11 on x64, build 22621 or newer. Local use does not require an ASL account. Sensor visibility depends on the hardware, drivers and permissions available to Windows.
Local use and optional fleet views
Use Steward independently for the computer in front of you. Optional fleet reporting and remote views need their own setup and consent. A remote health view is not automatic authority to control another computer.
What this page does not promise
No fixed speed increase, temperature reduction or repair outcome is promised. A diagnostic observation needs interpretation, and missing sensor data is not a healthy reading.
A Windows PC health check that explains every finding
ASL PC Steward is for people who want a Windows PC health check without a cleaner that frightens them with a big number. It reviews processor and memory pressure, background processes, storage, Windows reliability history and the hardware readings your PC makes available, then shows when each problem was observed and the specific next step.
A Windows PC health check that explains every finding
As a PC health check app it changes nothing during an ordinary scan. It only cleans what you pick from explained categories, for example aged temporary files or crash dumps, and it asks you to confirm before anything is removed. It is a one-time $49.99 purchase on the Microsoft Store, with no subscription and no ASL account needed on your own PC.
A Windows PC health check that explains every finding
System requirements: a 64-bit (x64) PC running Windows 11, build 22621 or later. Which temperature, fan and power sensors it can read varies with your hardware and drivers, so some readings may be absent, and no speed gain or repair result is promised. PC Steward is a separate app from Microsoft's own PC Health Check. To compare it with other ASL tools, see which ASL Windows app fits your task .

Before you choose a PC checkup tool
A health check for your PC can mean two different things. Know which one you need before you pay for anything.
Before you choose a PC checkup tool
Can my PC run Windows 11? If you are thinking about upgrading to Windows 11, use Microsoft's free PC Health Check app . It tells you if your PC meets the requirements. Microsoft ended Windows 10 support on October 14, 2025.
Before you choose a PC checkup tool
Why is my PC slow or unstable? This is the question PC Steward is built for. It needs a 64-bit (x64) PC that already runs Windows 11.

What PC Steward adds
PC Steward puts processor, memory, background processes, storage, reliability history and available hardware readings in one place. Each finding says what happened, when it happened, and what to do next. Old crashes stay as history, so they do not drag down today's score. Low-space findings show how much more space you need, on the exact drive.
Good to know
It does not promise a faster PC, a cooler PC or a repair.
Good to know
A normal scan changes nothing. Cleanup only happens after you choose what to remove and confirm.
Good to know
A missing sensor reading is shown as missing. It does not mean all is well.
