TawohAwa Shares 7-Prompt Tutorial for Fixing Slow PCs with Claude Cowork

On October 25, @TawohAwa posted a series of threads sharing a complete tutorial for using Claude Desktop's Computer Use / Cowork features to "diagnose and fix" your computer. It consists of 7 ready-to-use prompts, positioned as a free alternative to IT technicians charging $100 per hour. The core design principle: Claude checks things and offers suggestions, but any actual changes require user approval to avoid risky system modifications or accidental data loss.

Confirmed

The tutorial has seven steps: Step 1 diagnoses the root cause of slowdowns, having Claude check CPU, memory, storage, and background processes, then rank fixes by importance; Step 2 reviews startup programs, identifying and recommending items safe to disable; Step 3 pinpoints apps consuming the most RAM and CPU, suggesting safe optimization methods; Step 4 analyzes storage usage, finding temporary files, large downloads, duplicate files, and unused apps, listing what can be safely deleted without deleting anything without permission; Step 5 checks browser extensions, tabs, and performance settings to find slowdown culprits while guaranteeing passwords, bookmarks, and browsing history remain untouched; Step 6 reviews system update status, security reports, and system health info, identifying outdated software, failed updates, or performance warnings and recommending fixes; Step 7 generates a prioritized, whole-system optimization plan based on all previous checks, executing only user-approved changes and summarizing the results.
To get started, download Claude Desktop and enable the relevant features (the overview post m7 provides the steps). Each subsequent prompt covers one independent step and can be used in sequence.

Why It Matters

The tutorial demonstrates a path for Computer Use / Cowork to move from "demo" to "practical personal IT maintenance": turning what would normally require a technician's item-by-item troubleshooting—startup items, memory, storage, browser, system updates—into a repeatable prompt workflow any user can follow.
Every step emphasizes a "suggest first, approve later" interaction model, exemplifying a practical paradigm for keeping AI controllable in system-level operations—a useful reference for writing similar tutorials.
