Yes. The most likely cause is that Edge and Outlook are starting with Windows or continuing to run in the background, which can slow startup.
Try these steps:
- Disable Edge from startup apps.
- Open Task Manager.
- Go to the Startup tab.
- If Microsoft Edge appears there, right-click it and select Disable.
- Stop Edge from running in the background.
- Open Edge.
- Go to Settings > System and performance.
- Turn off Continue running background apps when Microsoft Edge is closed.
- Check whether Outlook add-ins are contributing to the slowdown.
- Start Outlook in Safe mode by pressing and holding Ctrl while starting Outlook.
- If Outlook is faster in Safe mode, disable add-ins:
- In Outlook, select File > Options > Add-ins.
- In Manage, select COM Add-ins, then select Go.
- Clear add-ins that are not regularly used.
- Restart Outlook.
- Reduce general startup load.
- In Task Manager or System Configuration, disable unnecessary startup items.
- A clean boot can help identify whether another app is causing the heavy startup load.
- Check for general system causes of slow performance.
- Close other programs that are using memory and CPU.
- Make sure antivirus protection is running.
- Spyware, viruses, browser add-ons, low memory, and low disk space can all slow the computer and internet performance.
- If many Edge processes are still visible, that can be normal.
- Edge can show multiple processes because modern apps use separate sub-processes.
- The main issue is whether Edge is launching automatically or staying active in the background.
If the slowdown improves after disabling startup/background behavior, that confirms the cause was startup loading rather than normal multi-process behavior.

- What duplicate processes can I end in Task Manager (Windows 10) - Microsoft Q&A I have a very high number of duplicate processes running in Task Manager; under "Apps", "Background Processes" & "Windows Processes". Most of them are tagged "low" or "very low" power usage but overall, still using around 84-85% of memory.
- Computer has been working very slow - Microsoft Q&A I've been experiencing high CPU usage which has been affecting basic tasks. When I open up Task Manager, My CPU rises up to 100% for a couple seconds, then settles down to 80-90%. My Memory is also pretty high with it being 97% . I only have Microsoft Edge open. Is there any way for me to fix the performance?
