What if the Windows registry is accidentally deleted?

1, we use in Win XP to hide the shortcut small arrows registry modifier for example. The way to remove the small arrows in Win XP is to delete the "isshortcut" key values in the registry "Hkey_classes_root/piffile" and "Hkey_classes_root/lnkfile". In fact, it can be manually deleted, but the manual is too cumbersome, so we found the registry to automatically modify registry documents to help.

2. First, we create a Notepad document anywhere on the computer and change the extension to. reg.

3, with Notepad Open, is a blank Notepad document.

4, first, we enter the standard format, the first line to enter the "Windows Registry Editor Version 5.00" text.

5, the writing format is very important, in the same directory can not re-enter the directory, but the replacement of the table of contents remember the middle of the empty line.

6, first delete the hkey_classes_root/piffile in the Isshortcut, the first line of a blank line, that is, in the third line of input [Hkey_classes_root/piffile], indicated in the directory.

7, enter the "Isshortcut" =-on line fourth (quotation marks are required here).

8, and so on, we enter the deletion of the hkey_classes_root/lnkfile in the Isshortcut key value of the code, remember that in the directory to be wrapped between lines. Close and save, we double-click the registry key and the skill makes the registry change.

9, this is the simplest deletion function, I enumerate some common change methods very code:

1 Add a blank string value: "..." = ""

2 Add a value of 0 dword/qword/binary ... : "..." = "dword:0" (others, etc.)

3) Delete a value "..." =-.
