Windows All In One: FAQs & Getting Started

Getting Started With Your Renewed All-In-One

This guide will help you get set up, connect your devices, and troubleshoot common issues.

Step 1 Unbox & Check Your Items

Make sure you have everything:

  1. 24in Monitor
  2. Mini PC inside bracket (mounted behind monitor)
  3. Wireless Keyboard & Mouse
  1. USB Wi-Fi Adapter
  2. RGB Speaker Set
  3. Power Cord (x1), Monitor Power Cord (x1) & Video Cable (x1)
Windows All In One PC Cables

Step 2 Connect the Monitor & Power Cables

Let’s get everything plugged in.


1. Connect the Monitor: Plug the video cable into the back of the monitor and into the PC


2. Set Up the PC Power Cable: You’ll have two pieces for power: a power brick (adapter) and a power cord (wall plug)


3. If they are NOT already connected: Plug the power cord into the power brick


4. If/when they are connected: Connect the power cord into the back of the PC and plug the other end into a wall outlet.


5. Plug in the Monitor Power: Plug the monitor power cord into the port on the back of the monitor and the other end into a wall outlet.

Once everything is plugged in, you’re ready to connect accessories.

Step 3 Connect Keyboard, Mouse & Accessories


1. Open the mouse and remove the small USB receiver


2. Plug the USB receiver into the computer (this will connect both keyboard + mouse)


3. Plug in speakers


4. Plug in the Wi-Fi adapter (small USB stick)

Everything should be plugged in BEFORE turning the computer on.

Step 4 Turn On Your Computer

Press the power button on the computer and the power button on the monitor. Your screen should light up within a few seconds.

First startup may take a minute — this is normal.

Step 5 Follow Windows Setup

Windows will guide you through:

  • Choosing region
  • Connecting to Wi-Fi
  • Signing in or creating a Microsoft account

Setup may take a little time: Your PC may run Windows updates during setup, which can take a while depending on your internet speed. The screen may restart or pause — this is completely normal.

TIP:If you do not remember your Microsoft account password during setup, you can reset it using another device such as a smartphone, tablet, or another computer.

YOU’RE DONE! Your computer is ready to use.

All of our machines are loaded with a default level of Windows updates. However, Windows will need to install any additional updates released afterwards. Never turn your machine off in the middle of installing updates! This will corrupt your Windows installation.

Using a Microsoft Account (Windows 10/11): click “I forgot my password” on the login screen and follow the verification steps via email or phone to reset your password.

Still Locked Out?

You may need to reinstall Windows, which will erase your files. Back up important data if possible or consult a technician before proceeding.

Yes! Every BlairTech PC includes:

  • Windows Defender (Windows 10/11)
  • Microsoft Security Essentials (for older versions)

If you install another antivirus, uninstall Windows Defender first to avoid conflicts.

We do not install Microsoft Office on our computers as it is a paid service through Microsoft (Office.com). However, we install a standard, open source Office Suite that is compatible with Microsoft Office files. You can open and edit all the standard files that you create in Office.

Background apps, startup programs, and installed software can affect speed. Running updates, removing unused apps, and scanning for malware usually helps. Contact us for support if needed.

BitLocker encrypts your drive for security.

Go to: https://aka.ms/recoverykey

Sign in with the Microsoft account linked to your PC to find your recovery key.

No key found? You will need to reinstall Windows, which erases encrypted data.

At times, due to parts availability, we may upgrade your refurbished PC to a newer or more powerful model at no extra cost to you. This ensures you receive the best value and performance for your purchase, even when specific components are out of stock.

Step 1: Open Settings

Press Windows Key + I OR Click Start → Settings.

Step 2: Open Sound Settings
  1. Select System
  2. Click Sound
Step 3: Select Your Audio Output
  1. Under Output, choose your speakers or headphones from the dropdown menu.
  2. Click Test to confirm sound is working.

Tip: Ensure speakers or headphones are properly connected and powered on.

Step 4: Select Your Microphone
  1. Under Input, select the correct microphone.
  2. Speak into the microphone and confirm the input level bar moves.

If the bar responds, your microphone is working properly.

Still Having Trouble? Run the Windows Sound Troubleshooter
  1. In Sound Settings, click Troubleshoot under the affected device.
  2. Follow the on-screen instructions.

Windows will attempt to automatically detect and fix audio issues.

  1. Press Windows Key + X
  2. Select Device Manager
  3. Expand Audio Inputs and Outputs
  4. Select Uninstall Device
  5. Restart your computer

Windows will automatically reinstall the driver after rebooting.

It means you’ve been given a newer or higher-end PC model at no extra cost to you. This happens when the exact model you ordered sells out before your order is shipped.

No — all the key specifications (Processor, RAM, storage, graphics, etc.) remain exactly as you ordered. In rare cases, if specs did change, they will always be an upgrade, never a downgrade.

For example: If you ordered a PC with a 512GB SSD and we are out of stock, it may be upgraded to a 1TB SSD.

If you ordered a Dell OptiPlex 3060 and it is unavailable, you may be upgraded to a Dell OptiPlex 7060. The Dell OptiPlex 7060 is a higher-tier model than the 3060, offering faster performance, more upgrade options, and enhanced connectivity — so you’re getting more power and features at no extra cost.

Not at all. Your warranty and customer support coverage stay exactly the same.

The difference is in the model series or case, not the performance. In some cases, you might even receive newer internal components or a more recent model design.

We’d rather you get your PC on time or faster than wait for the specific model to come back in stock. This way, you get what you ordered, plus the added bonus of an upgrade!

Some HP computers may display the HP Sure Start Recovery message shown below during startup.

HP Sure Start Recovery Error Message

Microsoft is updating the security certificates used by Secure Boot, a Windows security feature that helps protect your computer during startup.

The original certificates were issued in 2011 and began reaching their expiration period in 2026. Microsoft is replacing them with updated certificates as part of an industry-wide security transition.

On some HP computers, this transition may cause an HP Sure Start notification to appear during startup.

For most customers, no immediate action is required. Select OK and allow your computer to continue starting normally.

We recommend keeping Windows Updates and HP updates current so your computer can receive the appropriate security updates as they become available.

Please do not change Secure Boot or BIOS settings unless specifically instructed.

Yes! Microsoft confirms that computers that have not yet received the updated Secure Boot certificates can continue to start and operate normally, and regular Windows Updates will continue to install.

If the message continues to appear or your computer does not start normally, contact BlairTech Customer Support and we can help. Click here to contact us.

Microsoft has published additional information about the 2026 Secure Boot certificate updates and how they are being delivered to Windows devices. Click here to read additional information.
