電腦管理打不開，出現提示“該檔案沒有與之關聯的程式來執行操作”

我的系統是win7的，電腦管理打不開，出現提示“該檔案沒有與之關聯的程式來執行操作”，於是百度了下，得到如下的解決方案：將下列文字用複製到記事本裡，然後將其尾碼名改為.reg，（如果沒出現尾碼名，點擊“電腦-組織-檔案和搜尋選項-查看-隱藏已知檔案的檔案名稱”將其前面的鉤去掉就好了）也就是註冊表檔案，然後雙擊此檔案，將其匯入註冊表。Windows Registry Editor Version 5.00[HKEY_CLASSES_ROOT/CLSID/{20D04FE0-3AEA-1069-A2D8-08002B30309D}/shell/Manage]@=hex(2):40,00,25,00,73,00,79,00,73,00,74,00,65,00,6d,00,72,00,6f,00,6f,00,74,/  00,25,00,5c,00,73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,6d,00,/  79,00,63,00,6f,00,6d,00,70,00,75,00,74,00,2e,00,64,00,6c,00,6c,00,2c,00,2d,/  00,34,00,30,00,30,00,00,00"MUIVerb"=hex(2):40,00,25,00,73,00,79,00,73,00,74,00,65,00,6d,00,72,00,6f,00,/  6f,00,74,00,25,00,5c,00,73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,/  00,6d,00,79,00,63,00,6f,00,6d,00,70,00,75,00,74,00,2e,00,64,00,6c,00,6c,00,/  2c,00,2d,00,34,00,30,00,30,00,00,00"SuppressionPolicy"=dword:4000003c"HasLUAShield"=""[HKEY_CLASSES_ROOT/CLSID/{20D04FE0-3AEA-1069-A2D8-08002B30309D}/shell/Manage/command]@=hex(2):25,00,77,00,69,00,6e,00,64,00,69,00,72,00,25,00,5c,00,73,00,79,00,73,/  00,74,00,65,00,6d,00,33,00,32,00,5c,00,6d,00,6d,00,63,00,2e,00,65,00,78,00,/  65,00,20,00,2f,00,73,00,20,00,25,00,77,00,69,00,6e,00,64,00,69,00,72,00,25,/  00,5c,00,73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,63,00,6f,00,/  6d,00,70,00,6d,00,67,00,6d,00,74,00,2e,00,6d,00,73,00,63,00,00,00
