Today I noticed the hard drive light on my laptop furiously flashing away. Given I had not started any applications yet I pulled up Performance Monitor to investigate. The 'Disk' tab shows 'Processes with Disk Activity' and TIWorker.exe was at the top, merrily reading and writing to my drive.

So, what is it?

My limited research (googling - a verb now!) suggests it is a Windows Installer, connected to the Windows Update Service. Even when you are not updating, it may be tidying and compressing old update files in the background!

There are multiple links to problems that used to be present with tiworker.exe, all reportedly resolved by Windows Updates (Guess what I'm doing next...)
