improving desktop performance for windows aero

If you fulfil the last bit of the Aero puzzle that is to have correctly installed graphic card driver, which must be Windows Display Driver Model ( WDDM), then Aero runs on 15 years old graphic card. That is mainly autostart DWM Desktop Window Manager Session Manager (UxSms) service and enable Desktop Composition (Windows 7 new graphic rendering engine).

In addition also brute force Aero to run. That is among others disable both checks for graphic card performance (see a note below) and for date of the graphic card driver. The above registry entries disable all Windows 7 checks regarding Aero, which could prevent Aero from running. These registry changes are mainly to improve games and older application and to force hardware rendering instead software one. You need to take ownership of some of these keys first to enable write in. Short of system restore / reverting to my HDD and starting again, are there any suggestions? Try a registry hack that should have forced it back on (thanks Google)ġ1. Uninstall KB2670838 (suggested fix if that doesnt work is sytem restore to before install, but as it was installed at some point during my migration, looking at that as last option really)ġ0. Read about a windows update that nuked Aero for some people. Uninstall video drivers, wipe with driver sweeper, re-install original driversħ. uninstall video drivers, wipe with driver sweeper, re-install latest driversĥ. says my twin EAH6870 cards are not Aero compatible (after 4 years of doing just fine)Ĥ. More importantly than some Windows prettiness, my games wont run!ġ. (a leftover from an experiment with Win7s built in RAID feature)Īt some point during the transition, I lost my Aero functionality, and the screensaver wont run because of a lack of Direct3d compatible device. I used Easus Partition Magic to do the job because the feeble Samsung migration software cannot handle dynamic drives. Ok, so I finally found time to migrate my home system to the Samsung SSD I bought about a month ago.
