Windows 7 system shutdown speed is slow

My friend's friend installed the Win7 operating system, it takes 5 minutes to shut down. She asked me why the shutdown is so slow. Is there any solution? In fact, not only my friend has this problem, I believe that most people also have this kind of confusion, but they don't care too much. It doesn't matter if the shutdown is slow.

I still solve this problem for everyone! in case for need. Here is a description for everyone:

1, start->Control Panel->Power Options->Enable Advanced Power Management.

2. Check the computer device manager to see if there are any hardware devices with driver problems. If so, reinstall the related drivers.

3, disk defragmentation. My computer - right click on the drive to defragment the disk -> Properties -> Tools -> Select the disk to open the "Disk Defragmenter" window -> Analysis -> Defragmentation -> System will start finishing, after the system is completed Will inform you.

4. Shut down all unused programs before shutting down, then shut down.

5, open the optimization master -> system performance optimization -> disk cache optimization -> remove the "WIN shutdown automatically clean up the page file" in front of the tick.

6. Do not load DLL files. In [Start] -> [Run] -> type [Regedit] - HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorer, create a double-byte value named AlwaysUnloadDLL with a value of 1. If you want to remove this optimization, just set the key to 0.

7. Disable the "NVIDIA Driver Helper Service". We generally do not need this service, and it will take up a lot of system resources. The method of closing is to open "Control Panel -> Administrative Tools -> Services" In the pop-up window, find and right-click the NVIDIA Driver Helper Service item, select "Properties", in the pop-up list box that has been started, select "Disabled".

8, modify the registry switch: In [Start] -> [Run] -> type [Regedit] -> [HKEY_CURRENT_USER] -> [ControlPanel] -> [Desktop], change the value data of the string value [HungAppTimeout] to [200], the string Change the value data of the value [WaitToKillAppTimeout] to 1000. Also in [HKEY_LOCAL_MACHINE]->[System]->[CurrentControlSet]->[Control], change the value data of the string value [HungAppTimeout] to [200], the character The value data of the string value [WaitToKillServiceTimeout] is changed to 1000.

9. If the above methods are invalid, I think it is still necessary to find a good system disk and reinstall the system.
