i've recently updated the graphics driver thru Dell's SupportAssist program, currently using 18.104.22.16821 on Windows 7.
After the update the aero effects became unavailable, no way to turn on.
Any advice how to solve this, do i need to revert back to older driver?
your proposed method is not available. Troubleshooting gives result saying that video card is not supporting WDDM, so Aero is not available.
If i would uninstall the current driver, then which one should is install again? Reason i'm asking as with the previous one (not sure which version was it), Aero was working fine, while with the newest i have problem as described.
after uninstalling everything i've tried with Intel's latest driver, it was not helping. Then uninstalled again, removed all drivers which were listed and then installed Dell's latest which finally solved the case.
