You will get this with most emulators. Most of the android solutions at the moment are run using a virtual machine that emulates android hardwear rather than directly from your machine. This is processor intensive. I was running Andy emulator for a week or so an that would idle between 30-50% CPU utilisation.
It did run some games ok however. I ran an AnTuTu bench mark test and it was about the same as a Galaxy S3 in terms of performance.
It seems random as to what will an wont run on it though.
I had no issues uninstalling it. I use IObit uninstaller though so cant comment on native windows uninstallation.
i will have to try it...this afternoon i have homeworks jeje, try this emu and new wacom bamboo feel drivers (instead of original of surface pro 2)
