Win7 system optimization program recommended

Windows 7 system will automatically run a lot of programs when it is started. Generally, there will be forty to fifty processes under normal circumstances, and the system's memory is limited. Running so many processes at a time will further slow down the system. In order to make the system run better and smoother, we can take optimization measures for the process.
Optimized solution for optimizing Windows 7 system processes:
First, click on the process - right click - go to service - open or stop.
Second, open the run command box to start - run - enter msconfig Enter Select to start, turn off some unnecessary programs. The service will also stop.
Select some of the above programs that you don't want to use to turn them off.
The following list can be closed:
audiodg.exe
process file: audiodg.exe
where path: (system installation directory disk) C:windowsaudiodg.exe
Chinese name: Microsoft Windows Explorer
Producer: Microsoft Corp.
belongs to: Windows Audio Device Graphic Isolation Program
dwm.exe
Process File: dwm.exe
Process Name: dwm.exe< Br>English description: N/A
Process analysis: Vista Aero Glass related programs, let Vista system have a vitrified 3D interface style.
Similarly, in Windows 7, there is also this process, making windows7 also have a vitrified 3D interface style.
Location in windows7: cwindowssystem32dwm.exe
Process ID: 2796.
Minimum working set 51200, maximum working set 2097088.
Process size: 90.5KB.
This is a process of the aero interface.
Always curious about the memory manager dwm.exe inside the task manager, windows xp does not have this process.
Guess is the aero interface, the result is switched to the Windows standard view, the dwm.exe process has not disappeared, but from the original 46M to 7M memory occupancy, free memory is still no more than 700M, (system configuration a total of 1 G).
Turning off the glass effect in the aero interface has no effect on the memory. Turning off effects and shadows on any interface has no effect on memory.
This is the desktop management window, and the memory occupancy rate is very large, so the VISTA system 1G memory can barely run.
This process can be turned off, but it must be closed three times, the process is ended in the task manager, the process is still after the first time, but it is gone after the end of the process, there is no process after the process is turned off. 3D effect, there is no animation fade effect when the window is maximized.
