TiWorker 50% of CPU and Updating doesn't work in any way

Yeah unbelievable, the Microsoft Engineers twiddle their thumbs leaving us users to suffer then comes in after a user is forced to turn off a function to get a useable computer. Appalling behavior.

Hi,

CPU usage will go high, if there are some unnecessary applications get loaded with the operating system.

I would suggest you to perform following steps and check.

Method 1: Run System Maintenance troubleshooter and check if it helps.

Follow the steps:

a)       Press Windows and X key together and select Control Panel.

b)      Click on Troubleshooting.

c)       Click on View all option on the left side of the Windows.

d)      Click on System Maintenance option.

e)      Click on Next and follow the onscreen instructions to troubleshoot the issue.

If the issue still persists, continue to the next method.

Method 2: We will check the functionality in safe mode with networking.

Step 1: Start your computer in safe mode with networking and check the CPU usage.

Refer this link to start the computer in safe mode.

If it works fine in safe mode with networking, let’s perform clean boot.

Step 2: Perform clean boot.

Clean boot will help us identify if any third party applications or startup items are causing the issue.

To do this, follow steps from this link:

Note: After checking the functionality in clean boot, follow the suggestions under “How to reset the computer to start as usual after troubleshooting with clean boot”.

Hope the information provided is useful. If the issue persists, reply here and we will be glad to help you.

Hi Glenn,

Glad to know that you have resolved the issue. Thank for sharing this information with us. We really appreciate your effort to resolve the issue.

Please post back if you have any issues related to Windows and we will be glad to assist you further.

I think the problem is what I've also been running into with Windows 10 (beta, yes, I know).....  some system process that is on that may be good for a novice is left on for everyone and is meant to run as a background process, yet it runs with Normal priority.

Windows Update shouldn't run as normal priority.  

As a programmer, I learned that the best way to get your programs running efficiently was to always have a slow PC around.  A slow PC will always make sluggish performance more apparent.

When installing this on an Inspiron Duo 1090, I found both this and the Messenger issue which keeps LiveComm.exe running at high CPU usage.  I always clean out the SoftwareDistribution folder under c:\windows but you periodically have these processes running that don't benefit me.  Search is always running in the background and yet i rarely search for something.  For me, I'd rather wait 15 seconds while it looks for something than to slow down everything else I have.  Honestly, the only thing I really use that indexing for is for the Music App which I'm not using until you get that OneDrive integration turned on.

So, I turned off that piece, added a firewall entry to block the LiveComm.exe from hitting the messenger servers there, and now I set Windows Update to check for updates but to not try to install them.  

So far so good.  I just wish I could schedule these checks to only do these types of things after hours instead of while I'm actively working.  If I have to wait 15 seconds while searching which I rarely do, then I'll do that.  No problem with that.

Still love Windows 8 and 10 though.
