Windows 10 & 11 · works offline by default
Your computer can tell you what is wrong.
Warden reads real signals off your machine, works out the cause, and proposes one specific command with the readings that justify it. It asks before running anything, then re-measures to check it actually worked.
Free · 45 MB · the AI runs on your machine unless you choose otherwise, and Warden always says which one answered
Everything that is supposed to help does one of three things.
Built-in troubleshooters find nothing
You run the Windows troubleshooter. It thinks for a while and says "Troubleshooting couldn't identify the problem." You are exactly where you started, minus five minutes.
Chatbots cannot see your computer
An AI assistant can discuss your symptoms, but it cannot read your event log, check what is installed, or confirm a fix worked. You end up being its hands and its eyes.
"Optimisers" invent problems to sell you
Scan, find 4,182 issues, pay to fix. The issues are registry keys that do nothing, and the improvement is unmeasurable. That is the point: an unfalsifiable claim cannot be checked.
The loop
The last step is the one nobody else does.
Reads
Fourteen collectors sample the machine continuously: wireless state, temperatures, drive health, services, the event log, privacy settings.
Reasons
A model picks the most likely cause from what was actually measured. On your own processor by default: no internet, no account, no key. You can add your own cloud key for a stronger one, and Warden says which answered.
Asks
You see the exact command, what it will do, and the test that will decide whether it worked, all before you approve. No timer, no default.
Proves
After running, Warden re-reads the machine and evaluates that test. "Fixed" is a measurement. If it failed, it says so and tries the next thing.
The model on your machine never writes a command. It chooses an id from a fixed list of seventeen reviewed actions, and the parameters are checked against what was actually observed on your machine. Warden will not connect you to a network it has never seen you use, or restart a device that is not there. The optional cloud model may write one, and Warden shows you the exact command, screens it, and never calls the result verified.
Tune-up
Nine settings that are wrong without anything being broken.
A processor capped at 60 per cent by a power plan nobody chose. Graphics drivers four years old. Automatic cleanup switched off. None of it is failing, which is exactly why nobody has found it. Warden checks on request, shows the reading, and can change it back.
If it cannot be measured, it is not listed
Every finding names a quantity Warden read before and can read again after. There is nothing here whose benefit is a feeling.
If it cannot be undone, it is not offered
Warden will tell you it found 1.2 GB of temporary files. It will not delete them, because deleting them cannot be reversed, so it cannot be offered under this rule. It suggests turning on Storage Sense instead.
If there is no right answer, it does not pick one
A capped processor is faster unplugged or quieter on your lap. Warden shows both costs and recommends neither, because it cannot know which you wanted.
And afterwards it tells you the truth about the result. Warden re-reads the same number and reports the difference, including when the difference is nothing. “No measurable change yet” is a result it is willing to print, which is the whole reason to believe it the rest of the time.
What it refuses to do
Seven problems Warden will not pretend to fix.
Not a disclaimer. It is a list enforced in the code: for these, the set of available actions is literally empty, so nothing can select one however confident it is.
A worn-out battery
No command restores a battery's chemistry. Warden measures the wear and tells you what to say to a repair shop.
A failing drive
SMART says the drive is dying. Software cannot un-fail it, and pretending otherwise costs you the window to back up.
Overheating under load
Dust, thermal paste and airflow are physical. A setting change would hide the reading, not fix the machine.
Running too hot
Same cause, same answer. Warden shows the temperatures and where they came from.
Thirteen areas, in the words you would use for them.
Internet & Wi-Fi
Whether you are connected, and whether anything loads.
Sharing & Discovery
Whether you can see shared printers and other computers.
Printing
Whether print jobs can reach a printer at all.
Sound
Whether anything can play audio.
Camera & Microphone
Whether apps are allowed to see and hear you.
Bluetooth
Whether headphones, mice and keyboards can connect.
Windows Update
Whether security updates are still arriving.
Search
Whether Start and File Explorer can find your files.
Battery
How much of its original capacity the battery still holds.
Storage
Drive health, and whether there is room left to work in.
Speed & Temperature
Whether the processor is being held back by heat.
Devices & Drivers
Hardware Windows has flagged as not working.
Clock
Whether the time is right, which secure websites depend on.
Stop guessing at your own computer.
Install it, open it, and read what it found. It will not change anything until you say so.
