Why I Have to Keep Task Manager Running in Windows July 2, 2017

Over the last year or so, my daily personal laptop has been running slower and slower.  For a variety of reasons, Windows performance and reliability tends to degrade over time.  Memory especially, but also disk and CPU have been pegging at 100 percent all too frequently.  I suppose I could wipe the system and start again from scratch, but that’s also a good indication that it’s time to get a new laptop.

I’ve upgraded to a new laptop, a midrange Core i5 quad-core system with 8 GB of RAM, running Windows 10.  That will fix my memory, CPU and disk problems, I thought.

Wrong.  My system still hung regularly.  So I started investigating in more detail.

Chrome, for one very big reason.  I will typically keep four or five tabs open, and it doesn’t take long for one or two of them to take up well over 2GB of memory.  And I’m talking about very commonly used sites, like weather.com, fitbit.com, or cnn.com.

While I’ve read several reasons (some of which are contradictory or don’t reflect my situation) why Chrome consumes memory like a drunken sailor, there doesn’t seem to be a whole lot to do about it.  Some talk about disabling add-ins; the only add-in I have running is Flash, and that is still required by many commercial websites (and crashes just as frequently).

Chrome has also been known to consume huge amounts of CPU and disk bandwidth.  I haven’t really read anything actionable about what to do here.

So I keep Task Manager open.  When a Chrome tab starts to misbehave, there is no alternative but to kill the process.

But wait!  It’s not just Chrome!  In Windows 10, there’s also this process called Microsoft Telemetry Service (and yes, it is a Windows Service).  I found this service using 99 percent of my CPU on more than one occasion.  What does Microsoft Telemetry Service do?  It sends use information from your computer to Microsoft.  Not just error information; use information.

It is enabled by default.  If you disable it, some of the Windows updates will re-enable it without telling you.

My very strong recommendation is to disable it and the horse it rode in on.  I guess this is what we deserve in the Facebook era, where we have no privacy.
