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?

    If your office app does not offer the update automatically as happened on my system,

    1 select the File option from the ribbon,

    2 then select Account (lower region of left hand band), 3 then Update options,

    4 update now.

    Problems fixed.

    Thank you @kenBell6

    Yes, the issue was an update for WinWord which eventually did not stop ! I followed your advice, it updated WinWord then closed Click-to-run, this service is still running but 0% CPU and Office apps arenot using 25% of the CPU !
