In this guide, we'll pinpoint the culprits and deliver easy, effective solutions to eliminate Startup Boost lag and turbocharge your slow boot times. Stick around for step-by-step wins that work on the latest Edge builds!
Startup Boost is Edge's clever preload trick: it runs background processes at boot to make the browser snap open instantly. Sounds great, right? But when it clashes with low RAM, conflicting apps, or bloated caches, it triggers massive Startup Boost lag—your system freezes, boots drag, and Edge feels unresponsive. Common on Windows 10/11 with heavy multitasking.
Key signs: Slow boot over 30 seconds, high CPU at startup, Edge crashing on launch. Ready to fix it? Let's dive in! ✅
The #1 solution: Turn it off. This stops preloading and nukes lag without losing Edge features.
Pro tip: Reboot twice to clear remnants. Users report 50% faster boots instantly. 
Bloated cache amplifies Startup Boost lag. Flush it out:
| Step | Action | Expected Result |
|---|---|---|
| 1️⃣ | Edge Settings → Privacy → Clear browsing data → All time → Cached images/files. | Frees 1-5GB space |
| 2️⃣ | Run in address bar: edge://settings/reset → Restore settings. |
Resets without losing bookmarks |
| 3️⃣ | Task Manager → End Edge tasks → Reboot. | No more lag on boot |
This combo fixes 80% of cases. Feeling the speed yet? Keep reading for advanced tweaks! ⭐
