How to back up the registry

General guide for finding and backing up common software registration information

Right now to install and use the software, there are many requests for us to enter the registration code or install registration information such as KEY, which has caused some trouble for computer enthusiasts. Sometimes even for some software that has been registered on our computer, it is a headache to find its original registration information. In response to this situation, the author has compiled the hiding places of the registration information of some commonly used software in the system for reference by those who need it.

Windows98 software registration information storage location: Registry [HKEY_LOCAL_ MACHINE \ Software \ Micro
"ProductKey" branch under soft \ Windows \ CurentVersion];

WindowsXP, WindowsServer2003 software registration information storage location: C: \ Windows \ System32 \ $ winnt $ .Ini file, can be opened with the "Notepad" program, of course, this is assuming that your WindowsXP, WindowsServer2003 are installed on the C drive;

Winrar3.0 software registration information storage location: C: \ Program Files \ winrar \ Rarreg.key file, you can use the "Notepad" program to open the copy backup, of course, this is assuming that your Winrar3.0 is installed in C: \ Program Files Clip

Photoshop7.0 software registration information storage location: "SERIAL" branch under the registry [HKEY_CURRENT _USER \ Software \ Adobe \ Photoshop.0 \ RegistraTIon];

Winzip8.0 software registration information storage location: "Name", "SN" branch under the registry [HKEY_CURRENT _USER \ Software \ Nico Mak CompuTIng \ WinZip \ WinIni];

HyperSnap-DX 5 software registration information storage location: C: \ Program Files \ HyperSnap-DX 5 \ HprSnap5.hs5lic file, of course, this is also assuming that your HyperSnap-DX 5 is installed in the C: \ Program Files folder;

ACDSee6.0 software registration information storage location: "LicenseNumber" branch under the registry [HKEY_LOCAL _MACHINE \ SOFTWARE \ ACD Systems];

The storage location of AnyDVD3.3 software registration information: "Key" branch under the registry [HKEY_LOCAL_MACHINE \ Software \ SlySoft \ AnyDVD \ Key];

Ahead Nero6.3.0.2 software registration information storage location: "Serial6" branch under the registry [HKEY _LOCAL_MACHINE \ SOFTWARE \ Ahead \ Nero-Burning Rom \ Info];

You may have to ask: In addition to the software mentioned above, where can I find a lot of software registration information? In fact, the registration information of each software will always leave some clues in the system. Generally speaking, the registration information may be distributed in some files with the extension INI file in the software's own folder, or in the system registry. For INI files, you can use the "Notepad" program to view, and for friends to find software registration information in the registry, you can use the method of entering keywords, that is, enter in the "Find" box of the Registry Editor After the software name and ";", and then enter keywords such as "license number", "serial", "regkey", "productkey", "serialnumber" and so on to search, it may be faster.

In addition, for the backup of software registration information, in addition to the manual recording method to save, you can also use some software to help us back it up. This kind of software is still quite a lot, you can find some by searching the Internet. In my experience, Aida32 software is a good choice. Aida32 is a sharing tool software related to system detection. This software is green software and can be used as soon as it is uncompressed after downloading. It can not only be used to detect various hardware in the system, but also help us to obtain registration information of some software. After running Aida32, click the "software" plus sign in the left pane, and then click the "license" that appears, we can see some of the software installed on your computer from the right pane Name and registration information. If you need to back up, you can right-click on the "License" item and select "Text" or "HTML" format from the pop-up "Quick Report (I)-License" drop-down menu to back up. You can also right-click the name of the software in the right pane to copy it to back up the registration information.

How to back up the registry

The registry is used to manage the system configuration, mainly to improve the stability of the system. Some problems that usually occur in the operating system, such as the system cannot start, the application cannot run, and the system is unstable, many of them are due to errors in the registry. As a result, these problems can be solved by modifying the corresponding data. Therefore, mastering how to properly back up and restore the registry can make each user use his computer more easily.

First, use the registry editor to manually back up the registry

The Registry Editor (Regedit) is a registry tool that comes with the operating system, through which you can make various modifications to the registry. Of course, "backup" and "restore" the registry is naturally its instinct.

(1) Backing up the registry through the registry editor Because modifying the registry sometimes compromises the security of the system, no matter whether it is WINDOWS 98, WINDOWS 2000 or even WINDOWS XP, the registry editor is "hidden" in a very hidden place In order to "please" it out of the mountain, it must be done by special means. Click the "Start" menu, select the "Run" option on the menu, enter "Regedit" in the "Run" window that pops up, and click the "OK" button to start the Registry Editor.

Click the "Registry" menu of the Registry Editor, then click the "Export Registry File" option, enter the file name "regedit" in the pop-up dialog box, select "Save Type" as "Registry File", and then Set the "Export Range" to "All", then select the file storage location, and finally click the "Save" button to save the system's registry to the hard disk.

After completing the above steps, find the folder where the backup file was saved, and you will find that the backed up file has been placed in the folder.

(2) Back up the registry under DOS

When the registry is damaged, WINDOWS (including "Safe Mode") cannot be entered, what should I do at this time? Backing up and restoring the registry in a pure DOS environment is another remedy. Let's take a look at how to back up and restore the registry in a DOS environment.

Backing up and restoring the registry through the registry editor under pure DOS has previously explained how to use the registry editor to back up and restore the registry under the WINDOWS environment. In fact, the "Regedit.exe" registry editor can not only be used in the WINDOWS environment It can also be used under DOS.

Although the function of the registry editor in the DOS environment is not as powerful as in the WINDOWS environment, it also has its unique features. For example, the registry is backed up in WINDOWS through the registry editor, but after the system has a problem, you cannot enter WINDOWS. At this time, you can restore the registry through the registry editor under pure DOS.

It should be said that in the DOS environment, it is rare to back up the registry. Generally, it is sufficient to back up in WINDOWS, but in some special cases, this method is very practical.

After entering DOS, enter the WINDOWS directory of the C drive, enter "regedit" at the prompt of the directory, and press the Enter key to view the usage parameters of "regedit".

The two files "system.dat" and "user.dat" are still needed to back up the registry through "Regedit", and the specific command format of the program is this:
Regedit / L: system / R: user / E filename.reg Regpath
Parameter meaning:
/ L: system specifies the path where the System.dat file is located.
/ R: user specifies the path where the User.dat file is located.
/ E: This parameter specifies that the registry editor is to export the registry. Leave a space after this parameter and enter the file name of the exported registry.
Regpath: Used to specify which registry branch to export. If not specified, all registry branches will be exported. Among these parameters, the "/ L: system" and "/ R: user" parameters are optional. If these two parameters are not used, the registry editor considers them to be "system.dat" and "" in the WINDOWS directory. user.dat "file. If you boot from a floppy disk and enter DOS, you must use the "/ L" and "/ R" parameters to specify the specific path of the "system.dat" and "user.dat" files, otherwise the Registry Editor will not be able to find they.

For example, if you enter DOS through the boot disk, the command to back up the registry is "Regedit / L: C: \ windows \ / R: C: \ windows \ / e regedit.reg", the command means to register the entire The table is backed up to the WINDOWS directory, and its file name is "regedit.reg". If you enter the "regedit /ED:egedit.reg" command, it means that the entire registry is backed up to the root directory of the D drive (the "/ L" and "/ R" parameters are omitted), and its files It's called "Regedit.reg".

(3) Use the registry checker to back up the registry The registry checker Scanreg.exe in the DOS environment can be used to back up the registry.

The command format is:
Scanreg / backup / restore / comment

Parameter explanation:
/ backup is used to backup the registry immediately
/ restore displays all backup files according to the time and date of the backup
/ comment displays the part related to the backup file in / restore

Note: When displaying the backup registry file, the compressed backup file is listed as a .CAB file. The word behind the CAB file is Started or NotStarted. Started indicates that this file can successfully start Windows. It is a good backup file, NotStarted Indicates that the file has not been used to start Windows, so it is not yet possible to know whether it is a good backup.

For example: if we want to view all the backup files and the parts related to the backup, the command is as follows: Scanreg / restore / comment
