In my new Acer Aspire V5-571G (i7-3537U, Ram 8GB, Hard Disk 1TB, GeForce 710M) I found an OEM version of Windows 8 completely compromised by all the crapware preinstalled by Acer: McAfee Internet Security Suite trial, Norton Online Backup trial, Office trial, Acer cloud, ebay, clear.fi Media, clear.fi Photo, Spotify, Cyberlink MediaEspresso, stupid Wild Tangent games, stupid toolbars and useless icons in system tray which create dozens of processes in autostart.
For each Acer driver there is a stupid icon in the system tray nobody cares. Why do the 3rd-party drivers still install and create new processes and new tray icons instead using what Windows 8 already have?
Windows Update is very very slow on this version of Windows 8 provided by Acer.
I've also noticed that the Windows System Protection has been disabled by Acer, why?
My 5 years old PC which runs Windows 8 Pro is a lot faster than this new Acer.
Now, I have upgraded my 2 PCs to Windows 8.1, but my 5 years old PC still remains a lot faster than this new Acer
