Free PC Health Check

Is your computer healthy? Find out in 60 seconds. TuneBit scans 10 areas of your system and tells you exactly what needs fixing — for Free.

No install. Under 5 MB. No credit card. No sign-up.

What TuneBit Checks

Every one of these checks is Free. 7-day free trial, no account required. TuneBit scans all 10 areas and tells you what it finds.

💾

Disk Space Free

Are your drives running low? TuneBit checks every drive and shows you how much space is left. Low disk space slows everything down.

🔄

Windows Update Status Free

Are your updates current? TuneBit checks if Windows Update is working and if you have pending or failed updates sitting around.

🔌

Driver Health Free

Are your hardware drivers okay? TuneBit looks for missing or broken drivers that can cause crashes, blue screens, or devices that stop working.

🚀

Startup Load Free

How many programs start when your computer starts? Too many startup programs make your PC take forever to boot up and use memory in the background.

🛡

Security Free

Is your firewall on? Is your antivirus running? TuneBit checks your security settings and warns you about anything that leaves you exposed.

🔧

System File Integrity Free

Are your core Windows files damaged? Corrupted system files cause random crashes, blue screens, and weird errors. TuneBit checks them all.

📈

Memory Usage Free

Is your RAM maxed out? TuneBit checks how much memory your computer has and how much is being used right now. Low memory means a slow computer.

📄

Event Log Errors Free

Is something failing behind the scenes? TuneBit reads your Windows event logs and finds errors and warnings you never knew about.

🔋

Power Settings Free

Are your power settings holding you back? TuneBit checks if your computer is set to save battery at the cost of speed — common on laptops.

🌐

Network Configuration Free

Is your network healthy? TuneBit checks your DNS settings, adapter status, and connection quality for problems that slow down your internet.

Your Health Score

After the scan, you get a score from 0 to 100. It tells you how healthy your PC is at a glance.

70
Sample Score
80 – 100: Healthy
Your PC is in good shape. Maybe a few minor things to clean up, but nothing serious. Keep it up.
50 – 79: Needs Attention
Some things need fixing. Your PC might be slow, low on space, or have pending updates. The report shows you exactly what.
0 – 49: Needs Repair
Your computer has real problems — corrupted files, security gaps, critical errors, or serious clutter. You should fix these soon.

It's Like a Doctor's Checkup — For Your Computer

You go to the doctor once a year. They check your blood pressure, heart rate, and bloodwork. They tell you what is fine and what needs attention. Then you decide what to do about it.

TuneBit works the same way. It scans your system — just like a screening — and tells you what is wrong. Then you use any of the 35 included repair tools to fix it. Try it free for 7 days.
