How do I run Aero automatically?

Hi every one, I'm happy to touch to the world again!!
I have a problem with Aero in Windows 7 32 bit.
When I Installed Windows the Aero effect was work automatically, But after few days every time I open my computer I have to run Aero manually by open (RUN) box and write (net start uxsms). I don't know what happened!! Maybe because of updates?
I want to start Aero automatically again? Can any one help me please?.
Thanks.

Welcome to Seven Forums Hani76. For starts, I'd run the Aero troubleshooter

Start> In search box type Troubleshooting> Enter> Under Appearance and Personalization> Display Aero desktop effects> Click on Next to run the troubleshooter

See if it finds any issues. A Guy

Run the System File Checker. Make sure to note the part about running it 3 times if it finds problems it cannot correct.

SFC /SCANNOW Command - System File Checker

try this,
type services in the start search window, click the result with the cog, in the services window that opens scroll down to desktop window manager session manager ,see if it is set to automatic, if not double click on it and in the new window that opens set it to auto in the dropdown ,
if it is already set to auto then on the left click stop the service , then re start it again see if that helps.
