PC Checkup
How healthy is your PC, really? Our free desktop scanner reads your drive health, memory, thermals, security and more — the things a website can't — and gives you an honest 0–100 score in about 30 seconds.
100% read-only. It never changes a thing and sends nothing until you choose to book.

100% read-only — it never changes a thing
The scanner only reads your system's health. It doesn't delete files, change settings, or touch your registry, and it sends nothing — data leaves your PC only if you click "Book", which simply opens a prefilled appointment form in your browser.
How the PC Checkup works
Is the scanner safe to run?
Yes. It's strictly read-only — it inspects your system's health and never deletes files, changes settings, or touches your registry. It also sends nothing on its own; data leaves your PC only if you click "Book", which simply opens a prefilled appointment form in your browser.
What does it check?
Ten real areas a website can't see: drive SMART health and free space, memory, CPU load and temperature, startup programs, Windows Defender status, pending Windows updates, problem device drivers, recent crashes and unexpected shutdowns, laptop battery wear, and how much temporary-file junk has built up.
Is it really free?
The scan is completely free — run it as often as you like. You only ever pay if you decide to book a repair, and we confirm the exact cause and price before any work starts.
Will it slow down or harm my PC?
No. The scan takes about 30 seconds, runs read-only, and closes when it's done. It doesn't install drivers, run in the background, or leave anything behind — it's a single portable file with no installer.
What happens after the scan?
You get a 0–100 health score with plain-language findings. If something needs attention, one click opens a prefilled booking — a remote session for software issues, or an in-person repair for hardware. Nothing is sent unless you choose to book.
When can I download it?
The scanner is in final testing and code-signing. The download button here will go live the moment it's ready — in the meantime you can book a remote diagnostics session and we'll take a look with you.
