What it does
Your PC has a lot to say.
Your PC has a lot to say.
My PC Doctor makes it understandable.
Every part of a Windows PC already reports on itself. The problem has never been the data — it is that the data is unreadable. Pick a part to see what is actually read, and what it means.
Processor
- What is read
- Model, cores, threads, base and current clock, and how hard it is working while the check runs.
- What you would see
- A laptop CPU sitting far below its base clock under load is reported, with the measurement behind it.
Good to know:
One check
One check.
One check.
A complete view of your PC.
Press it once. It reads the configuration, the processor and memory, every drive, the graphics and display, Windows itself, the network, the drivers and the firmware — and then explains all of it in one report.
Real screens from the shipped application, captured on a Windows 11 PC.
The report
Don’t just show the problem.
Don’t just show the problem.
Explain what it means.
Every finding carries four things: what it is, what was actually measured, how certain that makes it, and what you can do about it. Where Windows cannot answer, the report says so instead of guessing.
Memory
Attention- Finding
- 13.5 GB of 15.7 GB in use while the check ran.
- Evidence
- Sampled during the check, not estimated from the installed capacity.
- What to do
- Close what you are not using, or ask your engineer whether this PC has a free slot.
Windows Update
Attention- Finding
- Updates are pending a restart.
- Evidence
- Read from Windows’ own update state.
- What to do
- Restart when convenient. My PC Doctor never installs a Windows update itself.
Storage temperature
Unknown- Finding
- This drive does not report its temperature.
- Evidence
- The value was asked for and not returned.
- What to do
- Nothing. It is reported as unavailable rather than shown as 0 °C.

My PC Doctor Shield
Security that works with your PC.
Windows already has a great deal of security in it. Most of the time the real problem is that nobody can see which parts are switched on, which are being held off by something else, and what to do about it.
The honest positioning: My PC Doctor works with Windows Security and Microsoft Defender and adds security intelligence, visibility and assistance around your PC. If another security provider is active, My PC Doctor respects the existing protection.
- It has no scanning engine of its own.
- It never switches Microsoft Defender off, and never removes an antivirus you bought.
- It has no kernel driver, does not inspect network packets and does not decrypt traffic.
- It never offers a way around a Windows warning.
Microsoft Defender & Windows Security
Which antivirus Windows is actually relying on, how Defender is running, its engine and intelligence versions, and thirteen Windows protections listed as on, off, or held off by another product.
Anything that is off can be switched on from the page — through Windows’ own permission prompt, and the state is read back from Windows afterwards rather than assumed.
Smart Firewall
Windows Firewall in plain words: which network class this PC is on, which programs are already allowed, and what to do when a billing or accounting program cannot connect.
A decision you make is remembered against the program’s publisher, certificate and checksum, so you are not asked twice — and so trust cannot slide onto a different file with the same name.
Web & download security
Check a web address before you open it, and a downloaded file before you run it: HTTPS, the certificate, the shape of the address, the publisher, the signature, the checksum and where Windows recorded the file coming from.
Both are started by you. There is no browser extension, nothing watches your browsing and no file ever leaves the PC.
Good to know: When nothing is known about an address or a file, the app says so plainly rather than showing a green tick that would mean nothing.
USB Shield
Know what’s connecting to your PC.
What is plugged in, whether this PC has seen it before, and what shape a pen drive’s contents are — then Microsoft Defender’s own scan of it, when you press the button.
A drive that has not been used here before is reported as unfamiliar, never as dangerous. Nothing on a drive is deleted, moved or formatted.
Application Trust
Know which applications are trusted on your PC.
Every installed application with who signed it — Verified, Known, or Needs Review — identified by publisher, digital signature, certificate and SHA-256 rather than by file name.
A program that simply cannot be checked is said to be so, never treated as bad. Nothing is uninstalled or removed.
Ransomware Protection
Help protect important files with Windows security.
Whether Windows is guarding your Documents, Pictures and Desktop folders, what it has stopped, and how to let a billing or accounting program you use through.
Good to know: The protection itself is Microsoft’s Controlled Folder Access. My PC Doctor explains it, switches it on through Windows’ permission prompt and shows what it did.
Security Center
One place to understand security events across your PC.
Defender’s findings, firewall decisions, website and download checks, USB activity and applications in one list and one timeline — only what somebody actually has to decide about, with what happened, why it matters and what to do.
What you set aside stays set aside, and a summary can go to your engineer without any of your files.
Signal Correlation
Security signals, explained together.
My PC Doctor correlates security signals — a new USB drive, an unsigned program, a Defender warning — to help explain events that may need your attention, and shows every signal behind a conclusion.
Good to know: It explains what Windows and Microsoft Defender recorded. Only Defender ever calls something a virus.

Where to start
What do you want to check?
Pick what brought you here and see which part of the app answers it. This page does not examine your PC — it tells you where to look once you have installed the app.
Start with Check My PC
One check reads the processor, memory, storage, Windows and startup together, and says which of them is actually under pressure right now — with the measurement it read, so you can see why.
In the app: Check My PC → then Cleanup & Startup
My PC Doctor does not diagnose anything from this website. The check runs on your own PC, when you press it.
Gaming
Built for work.
Built for work.
Ready for play.
Evidence about what this PC can actually do, and where it is held back. No frame-rate promises, no percentage bottleneck, no overclocking.
Gaming Readiness
What the PC is built for, part by part, with the measurement behind each verdict.
GPU Intelligence
The graphics card in detail, its driver, its memory, and what the vendor tools report where they are installed.
Workload Analysis
What the PC is actually doing while you use it, sampled over a short observation rather than guessed from specifications.
Bottleneck Analysis
A verdict only when the measurements are decisively lopsided — otherwise it says the observation was inconclusive.
Storage analysis
Whether the drive a game sits on is the one holding it back, with read and write figures.
Display context
Refresh rate and resolution against what the monitor itself reports.
Tuning capability
What this PC exposes that could be tuned, and what it does not.
Good to know: My PC Doctor reports tuning capability. It does not overclock, change voltages, set fan curves or enable XMP — by design and by test.
Safe optimization
Improve what needs improvement.
Improve what needs improvement.
Not everything.
Improve what needs improving, not everything. There is no “Optimize Everything” button, and nothing changes until you press the thing that changes it.
ReviewYou see exactly what would change, with real numbers first.
ConfirmNothing happens until you say so — Windows’ own prompt where rights are needed.
ApplyOne change at a time, never a batch you did not read.
VerifyThe result is read back from Windows, so the app only reports what is actually true.
Temporary files
Windows and application temp folders, with the space each would return.
Recycle Bin
What is in it and how much it is holding, before it is emptied.
Windows caches
Update and delivery caches Windows keeps, and what is safe to clear.
Startup programs
What starts with Windows, switched off and back on individually.
Duplicate files
Byte-for-byte identical copies only, one copy always kept, extras to the Recycle Bin.
Windows file repair
Windows’ own system file checker and image repair, with a restore point first.
No feature in My PC Doctor permanently deletes one of your files.
Your engineer
When your PC has a problem,
When your PC has a problem,
your engineer already knows the PC.
This is the part no antivirus has. The shop that sold or services your machine is inside the app by name, and a service request carries the diagnostic evidence with it — so the conversation starts from what the PC actually said.
CustomerRuns a check on their own PC, when they want to.
My PC DoctorReads every part and explains what it found.
EvidenceThe findings, the measurements and the PC’s configuration.
EngineerThe shop that sold or services this PC — by name, with their branding.
Service requestSent from inside the app, with the evidence attached.
ResolutionThe shop sees the PC’s history, not a blank ticket.
- Your engineer’s name and your shop’s branding inside the app
- Call or message the shop from the app
- Service requests carrying the diagnostic evidence
- The PC’s configuration and history on the shop’s side
- Status of a request the customer raised
The customer only ever sees their own shop’s contact details — never ours.
For dealers & service centres
Turn every PC you sell into a long-term customer relationship.
For computer dealers, PC builders and service shops. Every PC you sell becomes a machine you can still see, support and be called about — instead of one that disappears out of the door.
Sell or service the PC
Install My PC Doctor at the counter
Register the customer’s PC to your shop
The configuration is recorded as sold
The customer runs checks at home
You receive the diagnostic evidence
A service request reaches you, not a forum
The customer comes back to your shop
Your brandingYour shop name and logo inside the app on every PC you register.
Your engineerYour name and number are the ones the customer sees.
Your customerThe relationship stays with the shop that sold the PC.
PC historyWhat was sold, what was fitted, and what has been checked since.
Diagnostic evidenceA described problem instead of “it is slow”.
Service requestsRaised from inside the app, with the PC’s own report attached.
After-sales supportA reason for the customer to return rather than search.
- Every PC is activated with a key. The free key MPCD-FREE-MONTH gives a month once the customer verifies an email or WhatsApp number; your own key covers the PC for as long as you sold it.
- Renewal is a shop action in the admin console — the app never shows the customer a payment link.
- If a licence lapses nothing the customer already has is deleted; the app opens on a renew screen.
How it works
Five steps, once.

Privacy
Your PC.
Your PC.
Your data.
Your control.
Nothing runs by itself: no background scanner, no tray icon, no scheduled task you did not ask for, and no “your PC is at risk” pop-ups.
Local diagnosticsThe check runs on the PC. The findings are produced there.
No document readingNo file’s contents are ever read. There is no scanner.
No photo scanningYour pictures, videos and documents are never opened or listed.
No passwordsNo saved passwords, no Wi-Fi keys, no credentials of any kind.
No browsing historyNo browser history, bookmarks or cookies are collected, and nothing watches what you visit.
No keystrokes, no screenNo keylogging, no screen capture, no remote control, no remote desktop, no file browsing.
When a PC is registered to a shop, the diagnostic summary and the PC’s configuration sync to that shop’s console — that is the customer’s own record of their own PC. No file contents, no personal folders, no file paths from your documents.

Improve
Safe optimization you control, one change at a time, with the result verified afterwards.
Connect
Your engineer, by name — not an anonymous support queue.
Who builds it

This build is not yet signed with a code-signing certificate, so Windows will show an unrecognised-publisher warning the first time it runs. We are not going to tell you to click past a Windows security warning as a matter of routine: the reliable way to satisfy yourself is to compare the SHA-256 above with the file you downloaded, and the easiest is to let the computer shop that supports your PC install it.
Questions
Plain answers to the questions people actually ask.
What is My PC Doctor?
A lightweight PC health and diagnostic assistant for Windows. It checks your PC part by part, explains what it found in plain words, shows you what is protecting the machine, lets you clean up safely, and connects you to the computer shop or engineer who knows it.
What does My PC Doctor check?
The processor, memory, storage and SSD health, graphics, display, network, Windows itself, its update state, system file integrity, crash history, installed drivers and any flagged devices, BIOS and firmware, power and battery, startup programs, and the protections Windows has switched on. Each finding says what was measured and how certain it is.
Does it work with Windows 10 and Windows 11?
Yes — Windows 10 (1809 and later) and Windows 11, in both 64-bit and 32-bit builds. In practice the app has been used and verified on Windows 11; Windows 10 is a supported target that has not yet been tested on a real Windows 10 machine.
Does it replace my antivirus?
No. My PC Doctor is not an antivirus and has no scanning engine. It works with Windows Security and Microsoft Defender, shows you what is protecting the PC, and can start Microsoft Defender’s own scan. If you have another security product installed and active, it is left exactly as it is.
Does it read my personal files?
No. No file’s contents are ever read — there is no scanner in the product. Documents, photos, browser history and saved passwords are never opened, listed or collected.
Does it slow down my PC?
It is not running when you are not using it. There is no background service, no tray icon and no real-time monitoring; the app opens when you open it and reads the PC while the check is running.
Can my computer shop use it?
Yes — that is what it is built for. A shop registers the PCs it sells, its own name and branding appear inside the app, and service requests from those PCs come to the shop with the diagnostic evidence attached.
Can I contact my engineer from the app?
Yes. The shop’s name and contact details are shown in the app, and a service request can be raised from inside it carrying the report the app produced.
Does it work with Microsoft Defender?
It is built around it. The Shield page reads Defender’s running mode, engine and intelligence versions, its own past findings and thirteen Windows protections, and can switch on anything that is off through Windows’ own permission prompt.
What happens when another antivirus is installed?
Windows allows one antivirus to watch files at a time, so installing a second one makes Windows switch Defender off. My PC Doctor names whichever product Windows is relying on, leaves it alone, and does not offer to remove it. The one case it flags is an expired product keeping Defender switched off, which leaves the PC with no active protection.
What happens if Quick Heal is installed?
Quick Heal keeps doing its job and My PC Doctor leaves it alone. Windows registers it as the active antivirus, which means Microsoft Defender steps aside, and the Shield page will name Quick Heal as the product Windows is relying on. My PC Doctor adds no engine of its own, removes nothing, and turns nothing off. The one thing it will point out is if the licence has expired, because an expired product often keeps Defender switched off and the PC ends up with neither.
What happens if Net Protector is installed?
Exactly the same. Net Protector remains the active antivirus, My PC Doctor names it as the product Windows is relying on, and everything it has set up is left untouched. My PC Doctor is not a replacement for it and does not compete with it — it explains the PC around it, and flags the case where a lapsed licence has left Microsoft Defender switched off.
What is My PC Doctor Shield?
Shield is the security part of the app: the Windows protections in one list, Windows Firewall explained in plain words with your own decisions remembered, a check you can run on a website or a downloaded file, and the USB drives plugged into the PC. It is a management, visibility and explanation layer over the security Windows already has — not a second antivirus.
How does the security shield work?
It is a management and explanation layer over what Windows already has: Microsoft Defender and Windows Security, Windows Firewall, the checks you can run on a web address or a download, and the USB drives plugged into the PC. It adds no detection engine, and it never works around a Windows warning.
Do I need an activation key, and how do I get one?
Every PC is activated with a key. Anyone can use the free key MPCD-FREE-MONTH: type it in when the app asks, then verify your email address or your WhatsApp number — either one is enough — and the PC is covered free for a month, with every feature. If you bought the PC from a computer shop, the shop may give you its own key, which covers the PC for as long as the shop decides. After that the shop renews it — the app never shows you a payment link. Nothing you already have is deleted if it lapses; the app opens on a renew screen and your history stays.
Know your PC.
Protect your PC.
Keep your engineer close.
