Find out what is wrong with your computer
A free diagnostic you run yourself. It runs 38 read-only checks covering disk health and encryption, backup, memory, whether Windows updates are actually installing, network and Wi-Fi security, antivirus and firewall, remote access, browser extensions and what each one is allowed to see, startup load, installed programs and which of them are out of date, user accounts, and the faults Windows has been recording about itself. Then it shows you what it found. If you want a technician to look at it, you can send the results to us in one click. Windows first. The Mac and Linux builds are written and not released yet.
No account. No installation. Nothing runs in the background afterwards. Not ready to download anything? Run the quick check first.
Download and run it
One file. It asks for administrator permission once, so it can read your disk and network settings, then opens in your browser.
See what it finds
Disk health, wear and free space. Whether the drive is encrypted and a backup is running. Windows updates and whether they are still installing. Security software, firewall, Wi-Fi encryption and remote access. Your browser extensions and what each one is allowed to see. What starts automatically, which installed programs are out of date, and recent system errors. One check asks Microsoft which programs have newer versions; everything else stays on your computer.
Send it to us, if you want
Enter your session code, read exactly what is collected, and tick the box. You get a reference number, we get the report, and a technician can pick it up from there. You are never obliged to send anything.
Get your session code
A session code does two things: it downloads the tool, and it is what lets the tool send its report back to us. We email it to you rather than showing it on this page, so the code belongs to your mailbox and not to whoever happens to be looking at this screen.
Tell us where to send it. If a Connected Geek technician has already given you a code, you do not need to request another: use the one you have.
Already have a code from a technician? You do not need this form: enter it in the download section below. Sent a request and nothing arrived? . Would rather not fill in a form at all? Call 248-648-1717 and we will issue one over the phone.
We use your email only to send the code and to reply about this computer. See our Privacy Policy.
Get the tool
The download is a single file that needs no installer. Nothing is added to your startup and nothing keeps running once you close it.
You are on a phone, so the tool cannot run here.
Go to fix.connectedgeek.net on the computer you want checked and type this code:
Nothing else is needed. The code is not a password and it only works with this tool.
Codes are issued by email. If you do not have one, request a code above and it will arrive in a minute or two, or have an earlier one sent again. A code lets you send us up to three reports; downloading the tool does not count against those.
Verify what you downloaded
SHA-256 of every file we publish. On Windows:
Get-FileHash .\<file> -Algorithm SHA256.
On macOS or Linux: shasum -a 256 <file>.
We have not bought a code signing certificate yet, so Windows does not recognise us as the publisher and shows a blue “Windows protected your PC” screen. That is Windows saying it does not know who we are. It has not found anything wrong with the file.
Do not just click past it. Check the fingerprint first, which takes about a minute and proves these exact bytes are the ones we published.
Still on Windows 10? Already on Windows 11?
The tool answers both questions about this computer, before you talk to anyone.
Windows 10
Microsoft stopped issuing security updates for Windows 10 on 14 October 2025. A Windows 10 computer only keeps getting security patches if it is enrolled in Extended Security Updates, and that programme ends on 12 October 2027.
Enrolling costs nothing if Windows Backup settings sync is switched on. The alternatives are 1,000 Microsoft Rewards points or a one-off $30. Businesses have a separate, longer programme that runs to 2028 at a price that doubles each year.
The tool reports whether this computer is past end of support, and whether it can take Windows 11 at all: it checks for the TPM 2.0 security chip and Secure Boot, which are the two things that most often block an otherwise capable machine. That is the difference between a settings change and a new computer.
Windows 11
Upgrading does not configure anything. A machine that moved from Windows 10 frequently arrives on Windows 11 with the disk still unencrypted, no backup running, a firewall profile switched off, and everything the old machine started at boot still starting at boot.
None of that shows a symptom. It shows up the day the laptop is left in a taxi, or the day the drive stops.
The tool checks BitLocker, backup, firewall, antivirus, drive wear and startup load, and tells you which of them are actually set up on this computer rather than which ones Windows offers.
Dates above are Microsoft's, not ours. See Microsoft's Extended Security Updates page.
Quick connection check
This runs in your browser right now, with nothing to download. It only sees what any website can see, so it tells you about your connection, not your computer's health. It is not a diagnostic. For that, use the tool.
No result here is stored, and nothing is kept when you close the tab. Measuring your connection does need four requests to our own server, which is how your public IP and the round-trip time are read at all; those requests appear in our web server's ordinary access log, exactly like loading this page.
What the tool does and does not do
It reads
- Make, model, operating system version, memory and firmware date. The firmware date is a floor on how old the computer is, not its real age, so the report says “at least” rather than a number
- Disk health, capacity, free space and how much of each drive's life has been used
- Whether the disk is encrypted, and whether a backup is set up and when it last ran
- Network configuration, including IP and DNS settings, and which programs on this computer accept incoming connections
- Whether the wireless network this computer is on is encrypted, and how. Not the network's name and not the router's address
- Whether Remote Desktop is switched on, and whether the firewall lets it in
- Security software status, when it last updated, and whether the firewall is on
- The names of programs installed on this computer, and how many of them have a newer version available
- The names and versions of your browser extensions, and what each one is allowed to do. Not your browsing, your history or anything you have typed into a website
- The names of the user accounts on this computer and which of them are administrators
- The programs that start automatically when this computer starts
- Whether anything on this computer is set to wipe the pinned shortcuts out of File Explorer, how many of those shortcut lists exist, how many folders are pinned and when the pinned one last changed. Not which folders are pinned and not the name of any file
- Whether Windows System Protection is switched on, how much space is set aside for restore points, how many restore points exist and when the most recent one was made. Not what any restore point was called
- The background services on this computer and whether each is running
- Which Windows updates are waiting to install, whether recent updates installed or failed, whether automatic updates are switched on, and how Windows Update is set up on this computer: whether it is paused, held back, hidden from Settings, or set to take updates from a company server instead of from Microsoft. Not the address of that server
- Whether this computer is joined to a work account or managed by an IT system. Not your employer's name and not your work email address
- Whether a previous version of Windows, or a previous service visit, left folders behind on the disk
- How long this computer takes to start up, and when it last restarted
- Which devices in this computer Windows reports as not working, or as switched off. Not a list of everything you have ever plugged in
- Recent system error events
- The name of this computer and, unless you choose to hide identifiers, the account name in use
- Any contact details you type into the tool
It never touches
- Your files, documents, photos or email
- Passwords, browser history, cookies or saved logins
- Anything you type into other applications
- Your computer after it closes. It installs no service and leaves nothing running
The tool shows you this exact list again before anything is sent, and nothing is sent unless you tick the box. It also offers a hide identifiers option, which replaces the computer name and account names in the report before it leaves your machine. Free-text sections can still contain identifying strings, so it reduces what is sent rather than guaranteeing anonymity.
One check contacts the internet, and only one. To list programs with a newer version available, the tool asks Windows' own package manager, which queries Microsoft's catalogue. Nothing about you or your computer is sent to do that. Every other check reads your computer and nothing else, including the Windows update check, which reads your machine's own last update scan rather than contacting Microsoft.
