Win7 system right click on the computer management can not open the prompt program is not associated how to solve

specific reasons analysis:
1, due to the accidental deletion of the ghost win7 system registry key value "IsShortcut" caused;
2. It may be caused by the invalidation of the CompMgmtLauncher.exe call caused by the installation of some incompatible programs.
Troubleshooting Steps:
1. First Win+R calls up "Run”, type regedit and press Enter to open the Registry Editor;
2, then expand and navigate to HKEY_CLASSES_ROOT\\lnkfile Click to see if the right pane contains the key name named IsShortcut. If it is not found, right click “New (N)”, “String value (S)”, rename it to IsShortcut;
3, then continue to locate HKEY_CLASSES_ROOT\\piffile, also check whether the right pane contains the IsShortcut key value, if not, the same is established, close the registry editor after completion, then log out of the system and log in again. (ps: If it is a fault caused by deleting the IsShortcut key value, this method can be solved perfectly, but the small arrow of the shortcut will also be restored at the same time)
4. If the above method still cannot be solved, then the problem is explained. Not caused by deleting the IsShorcut key. You can try the next method to fix it;
5, also open the registry, and then locate HKEY_LOCAL_MACHINE\\SOFTWARE\\Classes\\CLSID\\{20D04FE0-3AEA-1069-A2D8-08002B30309D}\\shell\\Manage\\command, the right window In the grid, the default value is double-clicked and changed to mmc.exe %windir%\\system32\\compmgmt.msc. Close the registry editor, at this time <; management & rdquo; should be able to open, this can be repaired due to the failure of the CompMgmtLauncher.exe call caused by the "management" can not open, the system will directly call compmgmt. Msc instead of CompMgmtLauncher.exe.
Note: Most of the causes of general faults are caused by the loss of IsShortcut key value, but it is not deleted by users. Many users are caused by using optimization software, so here is a suggestion that everyone must optimize the system. It is premised on the fact that the system functions well and works properly.
