What is Microsoft Edge Startup Boost and Why Does it Cause High Disk Usage?

Startup Boost is Edge's clever trick to preload the browser in the background, making it launch lightning-fast. It runs mini-processes at boot, keeping Edge "warm" for you. Sounds great, right? But on some systems—especially with slower HDDs or overloaded SSDs—it triggers relentless disk reads/writes, leading to 100% disk usage. Common culprits:

• 🔥 Resource-heavy preloading chews through disk I/O.
• ⚙️ Conflicts with antivirus or Windows updates.
• 📱 Outdated Edge versions amplifying the issue.

Result? Laggy multitasking, slow boots, and frustration. Time to fix it! 👆
