Rundll32 has stopped working error on running Windows System and Security Center

Asked By 0 points N/A Posted on -

I have a laptop that is using windows 7 OS. When I try opening Windows System and Security center I get an error saying, windows host process (Rundll32) has stopped working and that windows is checking for a solution to the problem. See the error below

“Windows host process (Rundll32) has stopped

 Working

Windows is checking for a solution to the problem…”

When I wait for windows to check for a solution, it stops and does not give any feedback and clicking the cancel button just makes the error appear after every one minute. I solved the issue once before by doing a system restore on my laptop after which the error disappeared for sometime before it eventually started appearing once more.

Does anyone know how to fix this problem?

Dear MaryJane,

There are many windows bugs associated with Rundll32 error and your s is one of them. It is related to utilities and programs you have configured at startup.

For this go to “Run” and type “msconfig”  go to “services” tab and see thoroughly either there is any unwanted service if so uncheck it. Then move towards next tab “startup” and check for which process “rundll32” command is executing, uncheck that application/process too. Click “Apply” and exit “msconfig”. Restart system to take effect. Hopefully problem is resolved. See the snapshot attached to have more clear picture.
