I have a Dell XPS 400 with a Pentium D 820 Dual Core 2.8 GHz. Bought this in 2006 and upgraded to 2GB RAM. Does this configuration supports installing Windows 8? Any major issues?
It works but it is NOT supported for windows 8.
If your CPU does not have Execute Disable Bit Security option in bios it will not install.
Not all processors have this feature.
All Pentium D Models seem to have the NX bit.
So the latest bios would be recommended BEFORE the upgrade.
VISTA will have issues before SP2
SP1 is required before SP2
Full install of SP1 and SP2 is recommended.

You should run the compatibility check available on the Microsoft support website.
Please post back and let me know if you need more help.
Thanks. I did run it and it seems supported. However wanted to check for any official word from Dell.
The only things I can't have is Secure Boot for root kits etc.
if you go on ebay you can get a pentium d 960 3.6ghz processor very cheap $20 to 70 and it has execute disable bit. also it will have a big difference in performance. instal in 10 minutes very simple. i have the exact same system..!!!!!
Thank you SpeedStep. I have no intention of going to Vista but it is still very useful information.
Great idea, xpsconfigure. I will certainly go looking for this. Thanks!
In place upgrade requires AT LEAST VISTA SP1. Otherwise the WIN8 upgrade is a Scorched earth install.
There are no WIN8 Drivers and never will be which means you may need to install drivers in VISTA SP2 compatability mode.
There are no 32 bit to 64 bit upgrades of any kind any version.
You can upgrade to Windows 8 Pro and keep Windows settings, personal files, and applications from the following Windows operating system editions:
Windows XP (Service Pack 3 or later)
Windows Vista with SP1
Cross-architecture installation (32-bit to 64-bit) Windows Vista with SP1 or later
Cross-language Windows Vista with SP1 or later
Cross-architecture installation (32-bit to 64-bit) Windows 7
Cross-language Windows 7
Cross-architecture installation (32-bit to 64-bit) Windows 8
Cross-language Windows 8
