A Cyber Cleanup: Reinstalling an Old Laptop into an AI Agent Machine with Gemini

Background

OpenClaw had just gone viral, and I had experimented with it on a MacBook. But given the security concerns, token cost, and limited production readiness, I stopped there.

When I later cleaned up my room, I found an old laptop from my undergraduate days collecting dust. During a conversation with Gemini, I started thinking about turning it into a lightweight engineering machine or server.

This machine is only meant for lightweight or experimental AI tasks. If you need heavy development, you will need better hardware.

The goal was simple: keep no private files, install the lightest practical system, and dedicate the machine to AI coding execution.

Why not buy a server?

  1. Save money
  2. Reuse old hardware
  3. Keep it fully private
  4. Learn by rebuilding

Preparation

  • A stable internet connection
  • An 8GB+ USB drive
  • A large backup disk

Useful software:

  • Gemini / Doubao / Qwen web apps
  • Snipaste
  • Antigravity or VS Code + Cline
  • Motrix
  • Rufus
  • Clash Verge
  • LocalSend
  • Chrome

The Process

Cleaning up files

I first cleaned up the machine’s files. Using Gemini, I exported a Markdown-style hardware profile and checked how long it had been since the last reboot: 248 days. The machine was full of fragments and leftover software, which helped explain why it felt sluggish.

I then used Task Manager and the installed-apps list, took screenshots with Snipaste, and asked Gemini to explain each process and app, and to generate an uninstall list. This uncovered a lot of vendor software, leftover packages, and resource-hungry preinstalls.

Downloading the system image

After discussing my requirements with Gemini, I chose Windows 10 Enterprise LTSC 2021 over Ubuntu 24.04 because of software compatibility and ecosystem support.

I downloaded the ISO via BT from next.itellyou.cn and used Motrix for P2P transfer.

Making a bootable USB

I opened Rufus, selected the ISO, verified its hash, and then wrote it to a USB drive.

Reinstalling the system

After one final backup check, I asked AI to generate a Markdown SOP for the reinstall process and carried it to another device for reference.

I used the BIOS settings to boot from USB and then installed Windows LTSC. SSDs did not need partitioning, while mechanical drives were partitioned normally.

After installation, I let Windows Update patch the system, which took about 30–60 minutes.

Installing the base tools

I installed:

  • 7-Zip
  • Windows Update Blocker
  • Defender Control
  • Clash Verge
  • ToDesk

Then it was time to configure OpenClaw / Claude Code / other AI tools.

Epilogue

As of 2026-03-23, I checked memory prices from two years earlier and found that they had surged from 900 RMB to 2,400 RMB. That is a good reminder of how much AI is changing hardware demand.

More and more document-heavy and decision-heavy jobs are being reshaped by agents. Whether AI is a bubble or a real transformation, the safe answer is still the same: keep up with the wave, or get left behind.
