Rainforest Woodwind win7 system how to solve Explorer.exe crash

Many friends like to right click on the computer icon in the win7 Ultimate system, select management to call the device manager, which is considered to be the most convenient and fast method. But recently upgraded rainforest woodwind win7 system found that http://www.windows7en.com/dngswin7/using this method often leads to Explorer.exe crash. I thought it was caused by the installation of third-party software, but the problem remained after reinstalling the rainforest woodwind win7 system.
Enter "Regedit" in the start /run; open the registry editor,
navigate to hkey_local_machineSoftwareClassesCLSIDShellManageCommand, operate.

Then, change the key value of 1 to:
%Windir%SYstem32MMC.exe /To %Windir%System32Compmgmt.msc to export the key value again, named CompMgmt.reg.
Note: The http://www.windows7en.com/Win7Down/replacement command used after the repair is a method of calling computer management under the XP system, but the Explorer.exe crash can still work normally.
Open management again and again, there is no crash of Explorer.exe. I hope that Microsoft will participate in the future to fix this problem.
PS: This method belongs to the veteran, and will use the commands under the XP system to get the instability of the new system. At present, not all Explorer.exe crashes will encounter this problem, there is a certain chance, the students who have this problem temporarily use this method to solve it.
