Windows 10 Unistack Service Group hogging CPU to 40% or more

8

2

CPU is in high load, consuming battery and with the fan always on. Examining Task Manager, I can see the Unistack Service Group taking 40%-45% of load. Specs of machine: Windows 10 Pro 64 bits on Intel Core I5 with 8 GB RAM. There is no way to stop this: Unistack services group did not exist in Services Panel or from Task Manager is disabling to kill the task. ¿How do I stop or fix this problem?

Thanks Moab but my problem is no related to running inside a virtual machine, so I can not give a new CPU to the execution environment. – Fidel Orozco – 2015-12-29T23:42:11.110

Hi Fidel, can you clearly state what your question is? It isn't clear to me even though you are suggesting that the load is too high. – projectdp – 2015-12-29T23:53:41.290

The Unistack Service Group is part of the Windows Store and this happens when you get App Updates. To "disable" the usage, disable the automatic App update in the Store options

and check for updates on your own and install them if you don't do work and you can ignore the higher CPU usage.

I found this is being caused by using the Mail and Calendar App in Windows 10. Stop using those and your CPU usage goes down. Need to wait for a fix from Microsoft.

nice pointer. turning mail's live tile off in the start menu is helping – ZJR – 2017-09-26T15:19:28.067
