Click-to-Run High CPU Usage

Anonymous

Recently I noticed that there was a background application constantly running on my PC called 'click-to-run'. It runs from the moment I switch on the PC and it never stops and even if I stop the task, it will simply start again. It uses around 25% CPU load and when opening an Office app, like Word, that app uses another 25%. I am using Office 365 which I downloaded through the Education bundle which they offer. Is there a fix for this high CPU load please?

    Hello Stephen,

    Sorry to hear that.

    The Click-to-Run service is required during using Office and I would like to suggest you open one of Office applications, click File -> Account, on the right-hand Product Information panel, click Update Options -> Update Now. After updating and restarting Office application, you may check whether the Click-to-Run service still consuming high CPU resources.

    If the problem persists, could you upload a screenshot to show the update channel and detailed version of Office? I may directly do some tests with the specific Office suite.

    *On the Product Information panel, you can find the update channel and detailed version of Office on the About Word/Excel/PowerPoint section.

    We appreciate your feedback.

    Best Regards,

    Hugo

    I updated Office, unfortunately the problem still persists and Click-to-run still starts on boot up and still consumes 25% CPU constantly. 

    This is my About section screenshot, hope it helps.

    Thanks in advance.

    Hello Stephen,

    Thanks for the screenshot, during tests with the latest 2005 (Build 12827.20336) of the Current Channel (Preview) channel, I could find the problem of "Click-to-run process High CPU usage" only when the Office updates. After that, it works normally.

    I noticed the Microsoft Word application also consume high CPU, may I confirm the problem still persists after the updates? If so, Would the "Click-to-run process High CPU usage" problem persists after closing all opening Office applications? I'm thinking whether Click-to-run process needs to complete some tasks required in the opening Word documents.

    If the "Click-to-run process High CPU usage" problem persists even you have closed all Office applications, I would like to suggest you perform Online Repair to repair the Office suite.
