Hi everyone,

I've been having problems with high cpu usage from ntoskrnl.exe (40-50%). Unfortunately, using windows performance analyzer shows it's not just one process running on high the whole time, but a bunch of different processes called "node.exe" that will cycle on and off continuously every second (see screenshot).

I've updated drivers and tried changing settings on bios, but can't figure out what is going on.

Thanks for your help!

Node.exe is driven by Evented I/O for V8 Javascript which appears to be part of Photoshop (perhaps attempting to check a license).  I do see Evented in your task manager snip and it is hugely evident in your wpr trace.  I would try killing it in TM and seeing if it resolves the issue and if it does prevent it from running and see if PS complains. 

Just to be sure, since it is javascript, I would run a malwarebytes scan .

Please download the free version of Malwarebytes. Update it immediately.
Do a full system scan
Let us know the results at the end.

The details are as follows: Windows Firewall has blocked some of the features of Evented I/O for V8 Javascript on all public and private networks. The publisher is Joyent, Inc. and the path is C:/program files/adobe/adobe photoshop cc (64 bit)/photoshop-node.exe. My question, is it safe to allow Evented I/O for V8 to communicate on private and/or public networds?
