To fix a slow PC using “StopAutorun” settings, you need to manage your Startup Apps, which prevents unnecessary programs from launching automatically and hogging your system memory. While third-party optimization tools often market this feature as a proprietary “StopAutorun” setting, Windows has this capability natively built right into its operating system for free. How to Access the Native “StopAutorun” Settings
You do not need to download extra software to stop apps from automatically running. Use the native Windows Task Manager to control them:
Open Task Manager: Press Ctrl + Shift + Esc on your keyboard.
Expand the View: If you see a simple, small window, click More details at the bottom.
Navigate to Startup: Click the Startup apps tab (icon looks like a speedometer or a puzzle piece in Windows 11) or the Startup tab (Windows 10).
Identify Resource Hogs: Look at the Startup impact column. Focus on apps listed as High or Medium.
Disable the App: Right-click the unnecessary app (e.g., game launchers, chat apps, cloud syncs you don’t use daily) and click Disable. Additional Ways to Stop Background Slowness
Managing your startup programs is the fastest way to free up memory, but if your PC is still lagging, combine it with these built-in fixes:
Turn Off Background App Permissions: Go to Settings > Apps > Installed Apps, click the three dots next to a non-essential app, select Advanced options, and change the background apps permission to Never.
Run a Malware Scan: Malicious software often sneaks into hidden autorun folders. Type “Windows Security” into your taskbar search to open the app, and run a Quick Scan under Virus & threat protection.
Clear Temporary Storage: Type “Disk Cleanup” in your search bar, select your main drive, check the boxes for temporary files, and click OK to instantly reclaim speed lost to cached data.
If you would like to dig deeper into what is specifically slowing down your system, please tell me: What version of Windows are you currently using?
Does the lag happen right when booting up or after you have been using the computer for a while?
