Since installing Outlook 2013 I noticed that officeclicktorun.exe has been consuming the most CPU of any running app.  It takes focus of the machine when I'm in the middle of working on another app which is very annoying.

I understand that it's installed on any machine with an Office 2013 product and automatically set to run.  I can't understand why a simply update program would consume so much CPU.  Is this a known issue?

I found that there is a scheduled task that was set to run automatically. I turned that off and now the program won't run until I run Outlook.  But once I run that, the program takes off and becomes a resource hog. 

I went to Office -> Office Account and disabled all updates.  The program still runs like crazy.  I tried disabling the service but then Outlook won't start.  How can I use outlook without an additional app that appears to be a resource hog?

I got in the habit of using Outlook and then killing that .exe.  That doesn't work.  The .exe keeps coming back for no known reason.  I can disable the service to get it to stop running again but then I have to re-enable the service if I want to run Outlook again.  This is crazy!

I can't believe that a simple method of stopping all automated upgrade activity isn't being provided by Microsoft.

Hi,

Officeclicktorun.exe runs as a service named 'Microsoft Office ClickToRun Service' (ClickToRunSvc). It helps manage resource coordination, background streaming, and system integration of Microsoft Office products.

As far as I know, this service is required to run during the use of any Microsoft Office program, so you cannot just stop it permanently.

It shouldn't consume "that" much CPU. Is your Outlook update to date? Try to update it to the latest version and then verify result. Or you might need to repair your Office 2013 and see if it's due to an improper installation.

It IS consuming a lot of CPU.  As noted, what's most annoying is it will cause other apps to lose focus (i.e. when I'm writing in a browser).

I don't need "resource coordination, background streaming nor system integration".  If all it's doing is checking for updates why does it use so much CPU?

I installed Outlook2013 from the website.  I could understand it needing to update soon after being installed.  That's normal.  Why EVERY time I use it EVERY day is it doing all of this activity?  And now that I have updates turned off it shouldn't do anything right?

I will try the OffCAT tool. However, I must admit I'm losing confidence that MS can deliver new products without introducing MORE problems.  I'm going to be buying a new computer soon and, after using Office products for over 20 years, I am looking into Office alternatives.  I expect more from the largest software vendor in the world.

So how is it going after the OffCAT scan? I'm runing Office 365 on my PC which works just pretty well.

"I have updates turned off it shouldn't do anything right?" - Not only the update stuff, it's responsible for lots of things as listed above..

I rather doubt that it's due to an inproper install, so just repair your client as suggest above, then come back with the findings..

The OffCAT scan didn't do anything.  I found that Outlook 2007 was not fully uninstalled so I uninstalled that. Note that I still use Office 2007 for Excel, Word, etc.  I think this is a big part of the problem.

Despite having the updates turned off I still find that officeclicktorun.exe and msiexec.exe occasionally use a ton of CPU.  I look at the event viewer but I can't figure out from that what app is being installed or why.  I just with Microsoft would provide software that allows admins to more easily configure at a lower level.

I also repeat "I don't need resource coordination, background streaming nor system integration". It is time to go to OpenOffice after so many years using MS. You have the freedom to do anything you want and its FREE. I paid my money for Office Home 2013 and I dont even have a DVD to re install as I wish but have to use my Internet - how ridiculous is that?. Same fro Windows 10, all kinds of restrictions and forcing you to use the cloud service and apps which no one wants. MS if you dont give consumers what you want you will not last much longer.
