Anyway I have a hp530 laptop and it has vista home basic, it has obviously doesn't have the aero enabled. Anyway it when I tried to enable wddm using the .exe 'win 1583' which is the intel GMA945 graphics card intergrated, it seems it's customised or something by the manufacturer I then tried to download the drivers direct from the manufacturer which is HP and download them again. I know this is risky, but I'm hoping if anything goes wrong I can do a System Restore. So will the registry hacks work? (REG_DWORD): Composition Change the existing value to 1. Modify the following value (REG_DWORD): CompositionPolicy Change the existing value to 2. or will this work: HKEY_LOCAL_MACHINE\Software\Microsoft 4. Create a new registry branch called DWM. (If DWM doesn’t work, try to create and use WDM registry branch instead.) 5. Inside the HKEY_LOCAL_MACHINE\Software\Microsoft\DWM\ registry branch, create a new DWORD subkey called EnableMachineCheck. 6. Right click on EnableMachineCheck (or double click on it) to set the value to 0. 7. Repeat above two steps to create another DWORD called Blur, and set the value to 0. 8. Repeat again the steps to create another DWORD called Animations and set that to 0. I'm not so concerned about enabling aero on Vista Home Basic,(it would be nice though to play with aero b4 I get Win7), but I was planning to purchase Win7 Home Premium and I'm concerned I won't have any full funtionality with aero coz the manufacturer has decided not to put wddm 1.0 on intergated graphics card. By the way will this guys way about enabling aero on his machine help ;Aero Hack on Intel 915 ? SP 1 if you do a thread search it will come up(can't post a link until I hv 20+ posts). Anyway thanks for all your help, if it can't work, it's OK, I'll just have to live with Win7 Home without aero until I get a new laptop.
