visual studio problem

Hey guys need help. When i start searching a code in the entire solution by pressing ctrl+shift+f the visual studio not responding.

My machine is 64bit 4gb ram i5.

I dont know what is the problem.

If you're using Visual Studio .NET 2003, you need to disable your visual theme (Aero in Windows Vista & 7).

i tried but no luck

Edit: i fixed my problem. For those encounter this try this:

If you don't see "Compatibility" tab (I don't have this tab for devenv.exe in Win10x64Pro Preview),
run regedit.exe,
then go to HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers and create String value with name C:\Program Files (x86)\Microsoft Visual Studio .NET 2003\Common7\IDE\devenv.exe and value data ^ RUNASADMIN DISABLEDWM DISABLETHEMES
