What it tells you

All the things you would otherwise have to dig through Windows settings to find, written so they actually mean something.

💻

What your PC actually is

Make, model, processor, and how much memory it has, with a note on whether that is enough for what you do.

💾

Whether your drive is the fast kind

Tells you if you have an SSD or the older mechanical sort, how full it is, and how healthy it is.

🔋

Your battery's real health

How much charge it holds now compared to when it was new. Usually explains why it does not last like it used to.

🔍

Anything that needs attention

Crashes, drives showing wear, updates falling behind. Each one explained in plain terms, not error codes.

What could be improved

Upgrades that would genuinely make a difference to your machine, and what each one would actually change.

📩

A report you can send me

One button sets up an email with the report ready to attach. I will read it and tell you what I think, free.

What it does not do

I clean up after scams for a living, so I know exactly how wary you should be about downloading things. Here is the honest list.

  • It does not install anything. There is no setup and no program left behind.
  • It does not change any settings on your computer.
  • It does not delete anything.
  • It does not keep running once it has finished.
  • It does not send anything anywhere unless you choose to send it to me.
  • It does not touch your passwords, files, emails or browsing history.
  • It does not need an account or your email address to download.
  • You can delete the whole folder afterwards and nothing is left behind.

How to use it

Five steps, and you can leave it alone for most of them.

  1. Unzip the download first

    Right-click the file you downloaded, choose Extract All, then Extract. Open the folder that appears. This step matters, because if you run it from inside the ZIP your report gets saved somewhere you will not be able to find it.

  2. Double-click RUN_ME

    You will see a couple of security warnings at this point. That is normal and expected. There is a section below explaining exactly what they say and what to click.

  3. Click Yes when Windows asks permission

    Your battery's true condition and your drive's health readings can only be read with administrator permission. That is a Windows rule rather than my choice. The tool still only reads.

  4. Wait about a minute

    You can leave it alone while it works. It tells you what it is doing as it goes.

  5. Your report opens in your browser

    Read it yourself, or let it set up an email and send it to me. Entirely up to you. The report is yours either way.

The warnings you will see, and why

Windows shows warnings for anything downloaded from a small website rather than a big software company. You will see two or three. Here is exactly what they say and what to click, so none of it catches you out.

1. Your browser will say it is not commonly downloaded

What it looks like “ShrewsburyTech-PC-Health-Check.zip isn't commonly downloaded. Make sure you trust it before you open it.”

This is not a virus warning. It only means not many people have downloaded this particular file yet, which is true, because I am one person in Shrewsbury rather than Microsoft.

Click the arrow or the three dots next to the download, then Keep.

2. Windows may show a blue “protected your PC” box

What it looks like “Windows protected your PC. Microsoft Defender SmartScreen prevented an unrecognised app from starting.”

Same reason as above. Software companies pay for a certificate that makes this box go away, and it builds up trust based on how many thousands of people have downloaded the file. A local repair shop will never hit those numbers, so I would rather explain the box than pay to hide it.

Click More info, then Run anyway.

3. Windows will ask for permission

What it looks like “Do you want to allow this app to make changes to your device?”

Click Yes. Despite the wording, the tool does not change anything. Windows uses that same message for everything needing administrator access, including things that only read.

If you would rather not grant it, the tool will not run. That is a perfectly reasonable decision to make about software you downloaded from the internet, and I will not think any less of you for it. Just get in touch and I will help another way.

Your antivirus might grumble too

Some antivirus products are suspicious of any script that reads hardware information, because that is also something unwanted software does. There is nothing hidden here. The main file, Run-Diagnostics.ps1, is ordinary text. You can open it in Notepad and read every line of what it does before you run it, and if you know someone technical, so can they.

Making sure this is really from me

Worth knowing whether or not you ever download this. If you have been caught out before, have a look at my scam cleanup page too.

What is in the report

The report is saved onto your own computer. I cannot see it unless you choose to send it to me, so you should know what you would be sending.

It includes
  • The make, model and serial number of your PC
  • The parts inside it and their health readings
  • Your Windows version and Windows username
  • Your Wi-Fi network name and local network address
  • A list of programs that start with your PC
It does not include
  • Any passwords
  • Any of your files, photos or documents
  • Your browsing history
  • Your emails or messages
  • Anything you have typed

I need the serial number to look up the right parts and check whether anything is still under warranty. But if you would rather not send some of that, open the plain text version of the report and delete those lines first. That is completely fine and I will still be able to help with most things.

Common questions

Is it really free?

Yes. The tool is free, and so is me reading your report and telling you what I think. If it turns out you want work doing I will quote you for that, but there is no obligation and plenty of people just want to know where they stand.

Will it slow down or break my computer?

No. It reads information and writes a report. It does not install anything, change any settings, or keep running afterwards. You can delete the folder when you are done and there will be nothing left behind.

Does it work on a Mac?

Not at the moment, this one is Windows 10 and 11 only. If you have a Mac and want to know where you stand, just get in touch and I will go through it with you.

Nothing happened when I clicked the email button

That means there is no email program set up on the PC, which is completely normal if you use Gmail or Outlook in a web browser rather than an app. Just email me yourself and attach the file from the Reports folder. It is the one whose name starts with PC-Report_

It says my battery information is not available

Not every laptop reports its battery wear figures to Windows, and desktop PCs do not have a battery at all. That is a limitation of the machine rather than a fault, and everything else in the report will still be there.

Can I run it more than once?

As many times as you like. Each run saves a new report and keeps the old ones, which is genuinely useful. Running one before a repair and one after shows you what changed.

I would rather not run software I downloaded. Can you still help?

Of course, and that is a sensible instinct. Drop the machine round to the evening clinic and I will get the same information off it myself. The tool exists to save you a trip, not to replace one.

Ready when you are

Download it, run it, and send me the report. I will tell you honestly what I would do with the machine, including if the answer is nothing.
