Multiple explorer.exe process on startup

Question

Usually the 2nd explorer.exe consumes my RAM bout 2 gig or 1 gig and i didnt even open any explorer window in the background. I wonder is it caused by a software or just bug. ![](https://learn-attachment.microsoft.com/api/attachments/0984690d-1052-4c3d-9e5b-f1f0503ec8dc?platform=QnA

Hi Orang. I'm Greg, an Independent Advisor here to help until this is resolved.

1. Right click Start button to open Task Manager, show More Details, then choose Processes tab, scroll down to Windows Processes, then further down to Windows Explorer. Right click to Restart Explorer, then Restart PC.
2. See fixes for high explorer.exe RAM usage:

3. Go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done: http://answers.microsoft.com/en-us/windows/wiki...

Start with Step 4 to turn off Startup freeloaders which can conflict and cause these

issues, then Step 7 to check for infection the most thorough way, then step 10 to check for damaged System Files, and also Step 17 to test a new Local Admin account. Then if necessary continue with the other steps to go over your install most thoroughly.

4. Update your drivers and BIOS/UEFI firmware from PC or motherboard maker's Support Downloads web page, using the full model number, Serial Number or Dell Service Tag on sticker. Compare the latest drivers available for download with the ones presently installed in Device Manager reached by right clicking the Start button. Make sure you have the latest Chipset, Display (Video), Sound, USB3, Bluetooth, Network and all other drivers, or else download and install the latest now.

Then type System Information in Start Search, compare the latest BIOS/UEFI firmware version with the one showing in System Information, and install it following closely the instructions on the download page, and on any Read Me file included in download.

Updating drivers from the Device Manager or Windows Update is rarely enough. The most basic thing we need to learn to maintain a PC is keep the latest manufacturer's drivers installed from their Support Downloads web page.

5. If nothing else works then do a Repair Install, by installing Media Creation Tool, open tool and choose to Upgrade Now. This reinstalls Windows while keeping files, programs and most settings in place, is the most stable method to advance to the latest version, and solves most problems. http://windows.microsoft.com/en-us/windows-10/m...

I hope this helps.   Based on the results you report back I may have other suggestions if necessary.   If you will wait to choose whether the problem is resolved, then I will continue to help until the problem is fixed.
