    There are so many RunDLL32.exe in task manager, which slows down the system and even startup and restarts take much time. Help me out.

    OVER 160 RunDll32.exe in TASK MANAGER !

    Have you got lots of Rundll32.exe or svchost.exe processes running, or both?

    On a normal Windows 10 system, you should not have any Rundll32.exe processes running at all. Check your startup apps the see what is causing this:

    • Press Ctrl + Shift + Esc together to open Task Manager, click on the Startup Tab and see if there are any entries that are starting under rundll32, if there are, disable them
    • Press WIndows + R keys together to open the run dialog, type msconfig and hit enter. Click on the services tab and check the box marked 'Hide all Microsoft Services'. Then scroll through the list of services looking for rundll32 entries, if you find any,
      uncheck them and reboot

    With regards to svchost, i have noticed a huge increase in the number of these processes since the Creators Upgrade - I have 77 currently running on my system. They all are using 0% processor and HDD and on average about 1MB - 2MB, though this number does
    seem excessive . . .

    rundll32.exe error in windows 10

    This is caused by an entry in your Startup processes:

    • Press Ctrl + Shift + Esc keys together to open Task Manager
    • On the Startup Tab look for anything relating to this file (rundll32.exe)
    • If you find something related, select it and click 'Disable'

    If you did not find it there:

    • Press Windows + R keys together to open the Run Dialog
    • Type msconfig in the run dialog and hit enter
    • Click on the Services Tab of the resulting dialog
    • Check the box marked 'Hide all Microsoft Services'
    • Look for anything relating to this file (rundll32.exe)
    • If you find it, uncheck it
    • Click Apply and Reboot
