TiWorker.exe is file that comes with the Windows operating system, so I would not delete it. I'm not sure why it has high CPU usage.

Have you installed all available updates for Windows 8? If not, what may solve the problem.

I just received a message from Norton re: High Usage about this program. So my question is, is the program necessary? Is it safe to uninstall?

Thank you,

@Enda: TiWorker.exe is a legit file that comes with the Windows operating system. You can verify the authenticity of the file by looking at the "Digital Signature" tab, by right-clicking on the file and selecting "Properties". So, no I don't think TiWorker.exe should be removed.

I found a forum post over at technet.microsoft.com where a user, after looking at a performance log, claims that TiWorker.exe is compressing files in the Windows component store (WinSxS) directory.

I think that if you let TiWorker.exe run for a while, it will reduce its CPU usage and you'll have a little more disk space on your hard drive.

Did this solve the problem?

On Windows 8.1 TiWorker.exe is not digitally signed,
- it is in the right path
- size 190,464 bytes
- Version 6.3.9600.16384
Why wouldn't Microsoft sign this task?

@john: I checked my copy of TiWorker.exe on my Windows 8.0 machine. It's not signed with an embedded signature there either. It appears that Microsoft has stopped embedding the signature for this file, thus the "Digital signature" tab will no longer appear. Microsoft are most likely using catalog files to ensure the authenticity of the TiWorker.exe file on Windows 8.

Here's some info on .cat files:

OK, thanks - I checked using sigCheck.exe and it is signed, probably in a catalog as you say.

Im using Windows 10 and my Notebook is running at 100%CPU usage Its starting after 5 min idle and stops running when PC idle stops (moving mouse or pressing key)
This seems to be no big deal but if the Notebook is in idle for 1h CPU is running 100% for the whole time. This is causing an overheating of the notebook every time it starts.

Its "automatic maintenance" and cant be disabled (WHY!!)

To solve the problem i took control of the files (default permission is only to SYSTEM) and renamed the multiple tiworker.exe to tiworker.exe_disabled

Not Running anymore.

It has to be enabled again when you run windows update so i wrote a little rename script ^^

One thing: This is the last windows i will use. Next time i will use a good looking Linux and will install an illegal copy of windows for gaming!!!

@hans: I've also seen TiWorker.exe use a lot of CPU on one of my machines, but the CPU usage went back to normal after 2-3 hours.

yeeeeeah 2-3 hours, that's not going to completely screw the battery life of a laptop or mobile device at all is it, or prevent proper fast use of it.

The issue didnt exist in windows 7, started in 8 and it STILL exists in windows 10. And frankly I am sick of reading BS posts on multiple websites when I tried to google a solution, giving completely false information blabbering on about checking for updates and scanning for viruses....it has NOTHING to do with missing updates or viruses.

Microsoft doesn't fix bugs. There's no reason that this should use all remaining cpu. We should be able to cap cpu usage to something reasonable.
