Multiple usage

Question

When I sigh on to Edge it usually show many Microsoft Edge and outlook running sometimes 10-15 which slows down my computer. Is there any way I van fix that?

Answer 1

Windows is a multi-threaded operating system, because all processors these days have multiple cores and threads, Windows splits up large processes into smaller processes on the different processor cores, that is normal and that does not slow your PC down, it should actually make your PC faster, because a large app like a web browser is not using full cores on your processor.

Restart (not shut down) your PC to flush out your RAM.

Then when you are using Edge, open Task Manager (Ctrl + Shift + Esc).

Select the Processes tab, please provide a screenshot of that window.

How many tabs do you have open in Edge?

Answer 2

Seeing many msedge.exe processes is normal because Edge uses multiple sub-processes for tabs, extensions, and other browser components. The slowdown is usually caused by one or more busy tabs, extensions, background apps, or high memory/CPU use.

Try these steps in order:

1. Find the process causing the load
   • In Edge, press Shift+Esc to open the Browser Task Manager.
   • Sort by CPU or Memory.
   • Select the process using the most resources, then choose End process.
   • Check whether the computer becomes responsive again.
2. Turn off extensions
   • Go to edge://extensions/.
   • Turn off all extensions.
   • If performance improves, turn them back on one at a time to find the one causing the issue.
3. Turn on sleeping tabs
   • Go to edge://settings/system/managePerformance.
   • Turn on Save resources with sleeping tabs.
   • Set the inactivity timeout.
   • Add any sites that should never sleep to the exception list.
4. Use the Performance tool in Edge
   • Go to Settings and more > More tools > Performance.
   • If tabs are using too many resources, use the menu next to a tab to Sleep tab or Close tab.
   • When usage drops, the status returns to healthy/low usage.
5. Stop Edge from running in the background
   • Go to edge://settings/system.
   • Turn off Continue running background extensions and apps when Microsoft Edge is closed.
   • This helps if Edge keeps using CPU after all browser windows are closed.
6. Check hardware acceleration
   • Go to edge://gpu.
   • In Graphics Feature Status, verify hardware acceleration is being used.
   • If items show software-only rendering, make sure Use graphics acceleration when available is turned on in edge://settings/system.
7. Update or repair Edge if the issue continues
   • To check for updates: Settings and more > Settings > About Microsoft Edge.
   • To repair Edge in Windows: Start > Settings > Apps > Installed apps > Microsoft Edge > Modify > Repair.
   • Repair should not affect browser data and settings.
8. Reset Edge settings as a last step
   • Go to edge://settings/reset.
   • Select Restore settings to their default values.
   • This keeps bookmarks, history, and saved passwords, but resets pinned tabs, startup page, search engine, and extensions.

If Outlook is open in Edge, closing unused Outlook tabs can also help reduce memory use.
