WinXP Registry Application-the registry uses the full introduction of the eight _ registration form

Win XP registry Restore Simple One method

Win XP provides a new way to restore the registry in the following steps:

L Restart your computer, and when you see the "Select Startup operating System" message, press the "F8" key.

2. Use the arrow keys to highlight Last Known Good Configuration, and then press ENTER. Num LOCK must be turned off, and the arrow keys on the numeric keypad will work.

3. If you have a dual-boot or multiple-boot system, use the arrow keys to highlight the operating system you want to start, and then press Enter.

When Windows is successfully started, the registry reverts to its state when the computer was last successfully started. Selecting the last Known Good configuration is a way to recover a system from a problem, such as a newly added driver that does not match the hardware, but it does not resolve the problem caused by a corrupted or missing driver or file. and Windows restores only the information in the top hklm\system\currentcontrolset of the registry, and any changes made in other registry keys remain unchanged.
First, the basis of the registry:

(i) ******** system folder: *********

Name path meaning
AppData C:\Windows\Application Data Application
Cache C:\Windows\Temporary Internet Files browser caching
Cookies C:\Windows\Cookies
Desktop Desktop Desktop
Favorites Favorites Favorites
Fonts Fonts Fonts
History History History folder
NetHood NetHood Network Neighborhood
Personal C:\My Documents my document
PrintHood PrintHood Printer
Program Start Menu\Programs
Recent Recent document
SendTo SendTo sent to
The Start menu starts menus
Startup start menu\programs\ Start Group
Templates Temp temporary folder

When you need to modify the path of these system folders, simply go to the registry HKEY_CURRENT_USER\Software
\microsoft\windows\currentversion\explorer\shell Folders to modify the appropriate path.


(ii) Special folders for ******** systems *********

Some folders on our desktop or elsewhere are not real folders, they are just OLE objects that display the contents of a window folder, such as "My Computer", "Control Panel," and so on, they all have a system default class ID class identifier, Windows in the registry Hkey_ Classes_root\clsid Define these folder class ID descriptions

Control Panel {21ec2020-3aea-1069-a2dd-08002b30309d}
dial-up Networking {992CFFA0-F557-101A-88EC-00DD010CCC48} dial-up Networking
Internet Explorer {BFB23**2-E3F0-101B-8488-00AA003E56F8} browser
My Computer {20d04fe0-3aea-1069-a2d8-08002b30309d} My Computer
Network Neighborhood {208d2c60-3aea-1069-a2d7-08002b30309d} Network Neighborhood
Printers {2227a280-3aea-1069-a2de-08002b30309d} printer

Scheduled Tasks {D6277990-4C6A-11CF-8D87-00AA0060F5BF} scheduled task
My Documents {450d8fba-ad25-11d0-98a8-0800361b1103}
Urlhistory Folder {ff393560-c2a7-11cf-bff4-444553540000} URL history

(iii) icons for ************* files or other objects: *************

An icon is the identity of a file or object. There is only one icon for an ICO file, you can use "Path \ Icon file name" to indicate the icon of the file, for EXE, DLL and other files, they may contain more than one icon, then you need to have an index flag to indicate the first few icons, you can use the "path \ FileName, index number" To indicate the icon for the file.

If you want to modify the icon for the System folder, simply go to the registry's HKEY_CLASSES_ROOT\CLSID, find the class ID of the system folder, and then modify the icon file path in DefaultIcon, and if you want to modify the default icon for other files, you need to HKEY_ Classes_root\clsid\ the path to modify the icon file in the file type \defaulticon.

(iv) *************** drive automatic running function ************

When you turn on the autorun feature of the CDROM and put it on a disc that can be run automatically, the program on the disc runs automatically, so are other hard drives, moving disks, etc. running automatically? Key_users\default\software in the registry
\microsoft\windows\currentversion\policies\exploer can be seen under a
A NoDriveTypeAutoRun value entry in which the value indicates the drive that can be run automatically. The value entry is a 4-byte binary value, each digit of the first byte corresponds to a different drive, and if the corresponding position is "1," the autorun feature is turned off and the Autorun feature is turned on if the corresponding position is "0". The following table is the appropriate drive type for each of you
No. 0: Unknown drive 2nd: Removable drive 3rd bit: Hard drive
4th: Remote Drive 5th bit: CDROM drive 6th: RAM Drive
