About Adhen Prasetiyo & QuickFixLab

Hi, I’m Adhen.

My name is Adhen Prasetiyo. I’m based in Purwokerto, Central Java, Indonesia, and I’m the person who writes and maintains every article on QuickFixLab.

Before I tell you about this site, let me explain why I built it.

In 2023, my laptop suddenly couldn’t connect to WiFi after a Windows update. I spent three hours on Google. Every article I read had the same advice: “Restart your router,” “Run the network troubleshooter,” “Reinstall the driver.” I had already tried all of it. None of it worked.

Eventually — after almost a full day of trial and error on my own — I discovered the problem was a specific registry key that had been reset by the update. That solution wasn’t in any article I had read. After I shared the fix on Reddit, more than 200 people replied saying it had fixed their problem too.

That’s when I realized something: there are tons of tech problems where the actual fix is never written about properly on the internet. The big tech sites often just repackage information from Microsoft Support without ever testing the solution themselves.

I started QuickFixLab in early 2025 to be different. Every article on this site is based on a problem I encountered myself, or one I helped a friend or family member fix.

My Background

I’m not a Microsoft engineer. I’m not a certified IT professional with a wall full of certificates. But I’ve been the unofficial “tech support” for my family, friends, and neighbors for the past 8+ years.

Here’s what I actually do:

Web development and research — my main day job.
Bug bounty hunting as a hobby — I’ve received acknowledgments from a few platforms for vulnerabilities I’ve reported.
Building and maintaining custom PCs — managing a Windows desktop and several laptops at home.
Helping people fix computer problems — this is my most frequent activity and the inspiration for most tutorials here.

I don’t have an editorial team. QuickFixLab is a one-person operation. Every word you read here, I wrote myself.

Hardware I Use for Testing

Every tutorial on QuickFixLab is tested on real hardware before publication. Here’s my setup:

Lenovo ThinkPad T14 Gen 3 (Intel Core i5-1235U, 16GB RAM) — my daily driver laptop.
Custom Desktop (AMD Ryzen 5 5600, 32GB RAM, NVIDIA GTX 1660 Super) — for testing that requires a dedicated GPU.
HP Pavilion (~2019) — for compatibility testing with older hardware.
Samsung Galaxy A52 & iPhone 12 — for mobile fix articles.

Content Standards

Every article on QuickFixLab must meet these five standards:

Personally Tested: If I can’t reproduce the problem or the fix doesn’t work on my hardware, I don’t write the article.
User-Centric Order: Solutions are ordered by success rate (what works most often), not technical complexity.
Explain the “Why”: I explain the why, not just the how. Understanding the cause helps you solve similar problems later.
Honest Limitations: If a solution only works on specific hardware or carries risks, I state it clearly.
Regular Updates: Windows updates change things. When steps become inaccurate, I revise the article.

What I Don’t Do

No AI-Generated Articles: Every article is written manually based on real experience.
No Paid Placements: No brand pays me to recommend their products.
No Clickbait: Titles describe exactly what you’ll get, without exaggeration.

Topics I Cover

Windows Fixes (30+ articles): Error codes, updates, BSOD, networking.
App Fixes (11+ articles): Discord, Spotify, OBS, Teams, etc.
Browser Fixes (7+ articles): Chrome, Edge, Firefox.
Linux Fixes (11+ articles): Ubuntu/Debian issues encountered during dev work.

A Quick Disclaimer

Every solution I share on QuickFixLab is applied at your own risk. Hardware and software versions vary. If a step requires editing the registry or system files, always back up your data first. I am not a substitute for professional IT support for critical systems.
