Hive files are a better than REG files for backing up the registry. When you import a hive file containing a key, Regedit completely replaces the current key and all of its subkeys with the contents of the hive file. That means that Regedit removes any value you added since backing up the registry to a hive file. This is a far more accurate way to back up branches before editing them.

Exporting branches to hive files is similar to exporting them to REG files; you just pick a different file type. On Regedit's File menu, click Export. In the Save As Type list, click Registry Hive Files, type the name of the new hive file, and then click Save. Reverse the process to restore your settings: Click File, Import; then click Registry Hive Files in the Save As Type list, type the name of the hive file to which you backed up your settings, and then click Open. You can use any file extension you like, but I prefer to give hive files the .dat extension. The .hiv extension is also common for hive files. Don't confuse what you just learned about exporting and importing hive files with loading and unloading them. When you import a hive file, you're making changes to working parts of the registry. When you load a hive file, you're creating a whole new branch that Windows XP doesn't use. It doesn't read or change those settings, but they're visible in Regedit, so you can examine them. Unloading the hive file just unlinks the file from the registry. You can unload only hive files you manually loaded and not hive files Windows XP loaded. Whereas importing a hive file is a great way to restore an entire branch, loading a hive file is a good method to restore settings surgically or just to check an original value. First load the file in to the registry: Click either HKLM or HKU in Regedit; on the File menu, click Load, type the name of the hive file that contains your settings, and then click Open. Regedit prompts you for a key name, and you can type any arbitrary name that'll help you identify the hive. You'll then see that hive file under the root key into which you loaded it. Figure 3 2 on the next page is an example of loading a hive file that contains a backup copy of the key HKU \Control Panel\Desktop. Examine the setting in the hive file you loaded, or even copy the backup setting and then paste it over the current value. Don't forget to unload the hive, or else you won't be able to remove the file later.

Figure 3 2: The key Backup Desktop Settings is a hive containing a backup copy of HKCU\Control Panel\Desktop\ that I've loaded into the registry. Now that I hopefully have you sold on using hive files to back up settings before changing them, I'm going to introduce you to the ultimate way to back up registry settings: Console Registry Tool for Windows (Reg.exe). This command line tool comes with Windows XP and provides most of Regedit's features plus some. You learn its full use in 9, "Scripting Registry Changes." You can use it to save keys to hive files. You can also use it to restore, load, and unload hive files. With Reg.exe, saving a hive file is the same as exporting, and restoring a hive file is the same as importing. The best part is one of the tool's unique features: the ability to copy one key to another key, creating a quick backup copy of a key right there in the registry. So for example, I can copy HKCU\Control Panel \Desktop\ to HKCU\Control Panel\JH_Backup\ with a single command. Table 3 2 on the next page describes the Reg.exe command lines for each of these features. See 9 for a full explanation of all the different options. Table 3 2: Backing Up the Registry with Reg.exe Description Save the branch starting with the key keyname to the hive file called filename. Keyname begins with one of the root key abbreviations, HKCR, HKLM, HKCU, HKU, or HKCC. REG RESTORE Restore the hive file filename to the key keyname, replacing all of its keyname filename contents. Keyname begins with one of the root key abbreviations, HKCR, HKLM, HKCU, HKU, or HKCC. REG LOAD keyname Load the hive file filename to a new temporary branch beginning with the filename key keyname. Keyname begins with one of the root key abbreviations, HKCR, HKLM, HKCU, HKU, or HKCC. REG UNLOAD keyname Unload the hive file in the temporary branch beginning with the key keyname. Keyname begins with one of the root key abbreviations, HKCR, HKLM, HKCU, HKU, or HKCC. REG COPY keyname1 Copy the values in the key keyname1 to the key keyname2, creating it if keyname2 [/s] it doesn't already exist. Keyname1 and keyname2 begin with one of the root key abbreviations, HKCR, HKLM, HKCU, HKU, or HKCC. The option /s copies the entire branch, not just the values in keyname1.
