Optional download
DiagnoseMyPc Windows Scanner
You don’t need this to get a diagnosis. Describing the problem or uploading a screenshot works in your browser with no download, and gives you likely causes. The scanner is for when you want findings based on your PC’s own logs, drivers and settings.
Windows 10, 11 and Windows Server 2012 or later. Needs administrator permission to read system logs.

About browser and SmartScreen warnings
Newer downloads can trigger “not commonly downloaded” warnings in your browser or Windows SmartScreen. These warnings are there to protect you, so don’t skip past them by habit.
Only continue if you downloaded the file from diagnosemypc.com, the signer is Anthony Mazy, and the checksum matches. If anything doesn’t match, or you’re unsure, don’t run it — use the browser diagnosis instead, and email [email protected].
What the scanner does
- Asks for administrator permission, because Windows only lets admins read many system logs.
- Reads diagnostic data (event logs, drivers, services, updates, hardware health and more — full list below).
- Saves everything into a ZIP file on your Desktop. Nothing is uploaded until you upload the ZIP yourself.
- You can open the ZIP and read every file first. Uploaded ZIPs are deleted after the analysis finishes.

Step-by-step
Download the Scanner (optional)
You don't need this for the browser diagnosis. Download it only if you want findings based on your PC's own logs and settings.

Use the Download button on the diagnosemypc.com/download page. Don't run copies from other websites or email attachments.
Installer downloads (about 430 KB)
Your browser saves DiagnoseMyPc-Setup-v1.4.0.exe to your Downloads folder.
Check the file before running it
Right-click the file → Properties → Digital Signatures. The signer should be "Anthony Mazy". You can also compare the SHA-256 checksum listed on this page.
If your browser or Windows shows a warning
Newer downloads can trigger “not commonly downloaded” or SmartScreen warnings. Only continue if you got the file from diagnosemypc.com and the signer is Anthony Mazy. If you're unsure, don't run it — use the browser diagnosis instead.
Install, Scan & Review
Run the installer, let the app scan your system, and review the AI-generated report with suggested fixes.
Double-click the installer
Open DiagnoseMyPc-Setup-v1.4.0.exe from your Downloads folder (or click it in the browser’s download bar).
Approve the UAC prompt
Windows will ask for administrator permission. Click "Yes" — the scan needs elevated access to read system diagnostics.
Walk through the setup wizard
A plain setup window appears. Click "Next", then "Install". No custom options are needed.
Installation completes quickly
Because the installer is so small, setup finishes in a few seconds.
The app scans your system
DiagnoseMyPc runs its system checks. This usually takes under a minute.
Review, then upload the ZIP
The scan saves a ZIP to your Desktop. You can open it and read every file before uploading it on diagnosemypc.com for your AI report.
Exactly what we look at — and what we never touch
A diagnostic tool asks you to trust it with your computer, so here is the full list. No vague reassurances: this is what leaves your PC, what never does, and what happens to it afterwards.
What we collect
What you type
Your description of the problem, in your own words. We keep typed descriptions to improve the service and decide which help articles to write.
Anything you choose to paste in
Screenshots of an error, or output you copied from Command Prompt or PowerShell.
The optional system scan ZIP
Windows event logs, drivers and problem devices, services and startup items, installed updates and software, hardware and GPU details, crash-dump summaries, network configuration, firewall / Defender / BitLocker status, scheduled tasks and reliability history.
Your account email and past reports
So you can sign back in and reopen a diagnosis you already ran.
What we never collect
No personal files
Documents, photos and desktop contents are never opened, read or uploaded.
No passwords or Wi-Fi keys
The scan lists the names of saved networks only. It never requests stored keys.
No browsing history or cookies
Browser data is not part of any diagnostic category we collect.
No remote access
Nothing controls your PC or stays running in the background. The scan writes a ZIP file and exits.
No card details
Payments are handled entirely by Stripe. We never see or store a card number.
Never sold
We don't sell your data or use it to train our own AI models.
Sent over an encrypted connection
Nothing is uploaded until you pick a file or press analyze.
Analyzed once
What you submit is sent to a third-party AI service to write your report. Its own data-retention terms apply.
Files not kept
Scanner ZIPs are deleted when the analysis finishes, and screenshots are never saved to storage. Your report stays in your account, visible only to you.
Worth knowing before you upload
Windows diagnostic logs are plain text, so they can include your Windows account name and local network details wherever those appear inside a file path or a log entry. The scan saves the ZIP to your desktop first — you can open it and read every file before you decide to upload anything.
