From Stardock's newsletter I read "Handles are killing your PC" and checked in on the apps and handles to discover the stock Killer Network app was way out there at over 906,000 (906 THOUSAND) handles. This was a pretty interesting find and had me off to the maker for latest suite and drivers.
Result? The 906,000 number dropped to 900 handles or a thousand fold less.
Here's the full text of the message and link.
"Handles are killing your PC
The handle issue is a pretty big deal, and you may never have even heard of them. Let's fix that.
Right now, hit Ctrl-Shift-Esc. Go to the Performance tab. You will see the word "Handles" over on the right. On Windows 10, you should boot with around 60,000 handles used. This is actually pretty bad, but no biggie.
But, many people are starting to run enough programs to get over 100,000. And at around 120,000 handles... bad things start to happen. Your PC will get slow. Graphical elements might not show up. Programs may not launch. Long before you run out of memory, you will likely run out of handles - it's a problem that Microsoft really needs to fix.
So, what can you do?
Click on the "Details" tab. Now, right click on the name column, choose "Select Columns," and then choose "Handles." Now sort the list of processes by handles. Anything using more than 5,000 is not good (unless it's a game). But, keep an eye on anything using lots of handles and you should be fine."
Stardock didn't publish this except in their newsletter so here's a forum discussion about this issue.
