I am trying to build a new virtual desktop Pool in VMWare Horizon View 5 with Windows 8.1 clients. At the Moment, i am optimizing the image for best performance, including using an optimization script from Microsoft Technet. In this script there is a part where the visual effects in windows (Aero Peek...) are disabled by changeing registry keys. The problem is, these keys are placed unter "HK_Current_user", so if the script is, as proposed, run as part of the deployment, these changes do not affect new user accounts.
Now i've searched for two days to find a way to disable these visual effects for all new users - with these effects enabled, the VDI is extremely slow.
I found several pages that propose to change or create different registry entries, some under local_machines, for some i had to import the NTUSER.dat of the default user.
The Problem with all of these solution: they don't work. Maybe it is because they need another reboot to take effect. But our virtual desktops are reset after a user logged out.
I have VMWare Horizon View, i want to optimize an image for a new virtual Windows 8.1 Desktop, and i want to disable all the visual effects (Aero Peek...) for all new user profiles - because everytime a user is logged of, the virtual desktop is recreated, so a new user will get an unused, newly created machine.
Does anyone know a way to do this by Powershell, batch-file, GPO... But without the (not working) registry keys? Or does anyone know a way to do this with registry changes, even if the user can only log in one time - so without reboot, re-login?
EDIT: I now tried to create a whole new user profile with this manual. All steps work, but when i create a new user account, the visual effects are not disabled... is it possible that Microsoft has no way to set the default visual effects?
EDIT2: New crazy behavior: when a new user is created, the the settings in the GUI are sometimes very different. I am working with my clean installation now, befor i started to change reg keys, and now in the GUI the settings are set for best performance - but they are not realy set for best performance: all the features are still enabled, even if the GUI is telling something different. You have to change the settings, re-set it to Best performance, and then the features are realy disabled.
