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,

    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.

    Best Regards,

    Hugo

    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
