✅ What is Microsoft Edge Startup Boost and Why Does It Cause Lag?

Startup Boost is Edge's smart feature that keeps parts of the browser running in the background, so tabs and pages load instantly when you open it. Sounds great, right? But on older hardware, with too many extensions, or conflicting software, it hogs resources—leading to lag spikes, fan noise, and delayed startups. ⚠️

Common symptoms include:

• Slow Edge launch (5-10+ seconds)
• High idle CPU/RAM usage
• Stuttering during initial page loads
• System-wide slowdowns
