Was this ever addressed?
I have the same version of windows.
Groupy is using 11.3% CPU usage steady right now as I look at it.
Firefox is using 0.6% cpu usage
Display Fusion is using 0.5% cpu
and the other 8 programs/services using ANY cpu are all below 1%
I was going to reboot, however, when I did that I cancelled it because I have Macrium Reflect and I forgot that NOW is backup time.
Oddly enough, Macrium Reflect is running a backup and it's cpu usage has spike to 3%-4%, this is where I would expect groupy to be all the time-11% cpu usage is rather high-since I have attempted reboot though, groupy has dropped to 3.5%-then within 2 minutes or so down to under 1%
Groupy seems to be remaining under 1% after the reboot attempt which also stopped display fusion and Actual windows roll-up, two programs that with recent versions have conflicts with recent versions of groupy - I am not sure which programs are NOT playing nice with each other, but I DO know if I installed older versions of all of them they all work just fine together.
Of course each developer blames the other two, but that's just case of ALL three not wanting to spend the time/money finding out if it is REALLY their app causing the issue.
IF anyone of the developers was actually concerned they would simply purchase the other two programs and setup a test PC and debug, debug, debug. I have given up on that actually happening though, so using old versions works for me.
Eventually Windows 10 will implement tabs and a rollup button and then I can decided which features the 3 external programs give and which one I'd like to keep. Probably display fusion as it is the only one that seems to do the task bars the way I like them with included functionality that manipulates the desktop backgrounds in really cool ways.
Either way, my issue seems to be resolved by clicking reboot and then killing the reboot task.
So, MAYBE next time I kill all three programs from task manager then explorer itself and restart them - I could write a batch or script to do it I suppose.
