Wrong operating system

I am for a long time owner of this extremely expensive PC Gamer. My first impression was overwhelming from this great Teil.Ich had to try it immediately.
I read the part acting on me when installing Windows Vista 64 bit. At last he was ready and let's go I thought me.I installed my games and wanted to play, unfortunately I could not call Wolfenstein simply goes under Vista 64 bit not Anno 1404 can not be saved and and ...
I thought I would have a computer or games is GAMER anything differently? Well I have the option for 14.90 euros to upgrade to Windows 7. I register and wanted my upgrade aufrufen.Leider no, after long telephone calls with Acer (which are not cheap) I was told that my Serielnummer not yet in the system was, they had to manually enter and take nunmal 14 days.
Then I tried another DVD picture and sound are excellent but unfortunately this remains sound even further even if I stop the media player. Only a reboot assist.
From a hardware perspective, this calculator is really great, quiet and fast enough disk space, install a new hard drive comes in a flash,
Acer has made a big mistake extradite him with Vista 64 bit. Microsoft would adapt to these Pc would be that non plus ultra smooth you'd have awarded 10 stars, I can only hope that Windows 7 gets to grips with this hardware.
Nevertheless, I have to say the PC is great but we all know why Microsoft is not it?
