Hi Greg,

TiWorker.exe is Windows Modules Installer Worker. It is related to Windows Updates.

Method 1: I would suggest you to run system and maintenance trobulshooter and see if that helps.

a) Press Windows key + W key on your desktop.

b) Write Troubleshooting in the search box on the upper right hand corner.

c) Select the Troubleshooting option obtained after the search.

d) Click on View All option present on the top left corner.

e) Select the System Maintenance.

f) Click on Next to perform the System Maintenance troubleshooter and follow the steps.

Method 2: To resolve the issue with TiWorker.exe, check for updates in Windows Updates and install them.

a. Click on the Windows + X keys and select Control Panel.

b. Click on Windows Updates, in Large Icons View.

c. In the left panel, click on Check for updates.

Method 3: Perform a Clean Boot to see if there is any software conflict as clean boot helps to eliminate software conflicts.

Note: Follow How to reset the computer to start as usual after troubleshooting with clean boot from article KB929135 to reset the computer to normal mode.

Hi,

I would suggest you to run online virus scan to check if the issue is with virus.

Hi Vijay,

Thanks for your suggestion, I use AVAST! Internet Security Pro(PAID) & it found 0 problems, my thinking is I have inadvertently deleted needed files from WinSxS folder which was stupid on my part as I know not to mess with system files not knowing what their purpose is, I'm sure I'm not the only one to do this but maybe the only one to admit it & not blame it on the OS, LOL. Anyway I had no other choice but to re-install from a clean drive so I took the opportunity to install W10 & I am so glad I did.

I think this is by far Microsoft's best OS to date, so many great user friendly features & navigate with ease, too many changes I like to list but I do particularly like how quick it loads, about same as any Android phone, & the Task View feature when working with multiple windows, I added a sidebar with my favourite gadgets which is Always on Topso other windows dock to it.

Something is not correct with your hardware if you are having loading times as long as you state, I have installed many versions of Windows on many machines & have never had slow installs as you state, Windows 8 generally takes 25-45 minutes & update to 8.1 approx. 15 mins.

If I were you I would seriously check my hardware, a memory/ram issue can cause CPU lag problems especially if you have more than 1 module installed & their bus speeds are different, also incorrect motherboard BIOS settings and over-clocking is something that can cause CPU lag.

There are free software tools available for checking your hardware.

Cheers

My best option seems to be remove Windows and install Linux since the computer came with 8 and it took over 8 hours on my 1500kbs internet to download and install the 8.1 update. Even though I like Windows, I can use it when it will not run the programs you want and is unresponsive to anything you do. SFC took over 3 hours to run, booting in safe mode made no difference, all the fix-it programs said there was no problem, etc. When the computer does not start the programs up it will not allow me to shut it down either and sometimes 1 to 3 hours latter it will respond by opening up the program I wanted. From what I see (which corresponds to what I read elsewhere) is that windows module installer worker is compressing and decompressing certain directories non-stop with no way to stop it without a reinstall of windows. Any suggestions before my next step?

Mine still does it. It may work for a while and then load up the module installer worker for unknown reasons and run the CPU cycles up to 9- to 100% with the disk usage going up to 80+ %. The fix-it programs do not show any problems and scanning for corrupt files show no issues. This started around November when Windows locked the computer up for 3 hours to do the update. February was the worst taking over 8 hours, unable to use the computer while it updates. This behavior is exhibited every time Windows pushes out an update. What options do I have besides re-installing Windows? Since it came with Windows 8 and it took over 8 hours to update to 8.1, does it mean that I can expect a multiple day reinstalling of Windows? Will it allow me to re-install the programs that I have now since now it can take up to 2 days before it will allow me to install programs? (The last program I tried to install was Roots Magic and it sat for 2 days before it would allow the installer to run with the module installer worker running.)
