win7 修復左下任務欄不能鎖定程序

1.先在桌面上新建一個txt的文件名稱爲1，把下面的文字拷到裏面，把擴展名txt改爲reg：
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\piffile]
@="Shortcut to MS-DOS Program"
"EditFlags"=hex:01,00,00,00
"IsShortcut"=""
"NeverShowExt"=""
"FriendlyTypeName"=hex(2):40,00,25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,\
00,6f,00,6f,00,74,00,25,00,5c,00,53,00,79,00,73,00,74,00,65,00,6d,00,33,00,\
32,00,5c,00,61,00,63,00,70,00,70,00,61,00,67,00,65,00,2e,00,64,00,6c,00,6c,\
00,2c,00,2d,00,36,00,30,00,30,00,35,00,00,00
[HKEY_CLASSES_ROOT\piffile\shell]
[HKEY_CLASSES_ROOT\piffile\shell\open]
[HKEY_CLASSES_ROOT\piffile\shell\open\command]
@="\"%1\" %*"
[HKEY_CLASSES_ROOT\piffile\shellex]
[HKEY_CLASSES_ROOT\piffile\shellex\ContextMenuHandlers]
[HKEY_CLASSES_ROOT\piffile\shellex\ContextMenuHandlers\AVG8 Shell Extension]
@="{9F97547E-4609-42C5-AE0C-81C61FFAEBC3}"
[HKEY_CLASSES_ROOT\piffile\shellex\DropHandler]
@="{86C86720-42A0-1069-A2E8-08002B30309D}"
[HKEY_CLASSES_ROOT\piffile\shellex\IconHandler]
@="{00021401-0000-0000-C000-000000000046}"
[HKEY_CLASSES_ROOT\piffile\shellex\PropertySheetHandlers]
[HKEY_CLASSES_ROOT\piffile\shellex\PropertySheetHandlers\PifProps]
@="{86F19A00-42A0-1069-A2E9-08002B30309D}"
[HKEY_CLASSES_ROOT\piffile\shellex\PropertySheetHandlers\ShimLayer Property Page]
@="{513D916F-2A8E-4F51-AEAB-0CBC76FB1AF8}"

2.然後在新建一個2.txt文件，然後把下面的內容拷入，把擴展名txt改爲reg:
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\lnkfile]
@="Shortcut"
"EditFlags"=dword:00000001
"FriendlyTypeName"="@shell32.dll,-4153"
"IsShortcut"=""
"NeverShowExt"=""
[HKEY_CLASSES_ROOT\lnkfile\CLSID]
@="{00021401-0000-0000-C000-000000000046}"
[HKEY_CLASSES_ROOT\lnkfile\shellex]
[HKEY_CLASSES_ROOT\lnkfile\shellex\ContextMenuHandlers]
[HKEY_CLASSES_ROOT\lnkfile\shellex\ContextMenuHandlers\Compatibility]
@="{1d27f844-3a1f-4410-85ac-14651078412d}"
[HKEY_CLASSES_ROOT\lnkfile\shellex\ContextMenuHandlers\OpenContainingFolderMenu]
@="{37ea3a21-7493-4208-a011-7f9ea79ce9f5}"
[HKEY_CLASSES_ROOT\lnkfile\shellex\ContextMenuHandlers\{00021401-0000-0000-C000-000000000046}]
@=""
[HKEY_CLASSES_ROOT\lnkfile\shellex\DropHandler]
@="{00021401-0000-0000-C000-000000000046}"
[HKEY_CLASSES_ROOT\lnkfile\shellex\IconHandler]
@="{00021401-0000-0000-C000-000000000046}"
[HKEY_CLASSES_ROOT\lnkfile\shellex\PropertySheetHandlers]
[HKEY_CLASSES_ROOT\lnkfile\shellex\PropertySheetHandlers\ShimLayer Property Page]
@="{513D916F-2A8E-4F51-AEAB-0CBC76FB1AF8}"

3.這樣兩個最重要的文件就建好了，下面要做的就是把任務管理器打開，把“explorer”進程結束掉，然後點擊任務管理器的文件-->新建任務，把剛纔的兩個reg文件一次導入(就是找到那兩個reg文件分別打開,確定幾下就可以了)，再新建任務explorer.exe,看看是不是就可以程序和快捷方式pin如任務欄了!
