virt-win-reg - Export and merge Windows Registry entries from a Windows guest
virt-win-reg domname 'HKLM\Path\To\Subkey' virt-win-reg domname 'HKLM\Path\To\Subkey' name virt-win-reg domname 'HKLM\Path\To\Subkey' @ virt-win-reg --merge domname [input.reg ...] virt-win-reg [--options] disk.img ... # instead of domname
You must not use "virt-win-reg" with the --merge option on live virtual machines. If you do this, you will get irreversible disk corruption in the VM. "virt-win-reg" tries to stop you from doing this, but doesn't catch all cases. Modifying the Windows Registry is an inherently risky operation. The format is deliberately obscure and undocumented, and Registry changes can leave the system unbootable. Therefore when using the --merge option, make sure you have a reliable backup first.
This program can export and merge Windows Registry entries from a Windows guest. The first parameter is the libvirt guest name or the raw disk image of a Windows guest. If --merge is not specified, then the chosen registry key is displayed/exported (recursively). For example: $ virt-win-reg Windows7 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft' You can also display single values from within registry keys, for example: $ cvkey='HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion' $ virt-win-reg Windows7 $cvkey ProductName Windows 7 Enterprise With --merge, you can merge a textual regedit file into the Windows Registry: $ virt-win-reg --merge Windows7 changes.reg ПРИМІТКА This program is only meant for simple access to the registry. If you want to do complicated things with the registry, we suggest you download the Registry hive files from the guest using libguestfs(3) or guestfish(1) and access them locally, eg. using hivex(3), hivexsh(1) or hivexregedit(1).
--help Показати коротку довідку. --version Показати дані щодо версії і завершити роботу. --debug Увімкнути показ діагностичних повідомлень. -c адреса --connect адреса Якщо використовується libvirt, встановити з’єднання з вказаним URI. Якщо пропущено, з’єднання буде встановлено з типовим гіпервізором libvirt. Якщо вказати блокові пристрої гостьових систем безпосередньо, libvirt не буде використовуватися взагалі. --format raw Specify the format of disk images given on the command line. If this is omitted then the format is autodetected from the content of the disk image. If disk images are requested from libvirt, then this program asks libvirt for this information. In this case, the value of the format parameter is ignored. If working with untrusted raw-format guest disk images, you should ensure the format is always specified. --merge In merge mode, this merges a textual regedit file into the Windows Registry of the virtual machine. If this flag is not given then virt-win-reg displays or exports Registry entries instead. Note that --merge is unsafe to use on live virtual machines, and will result in disk corruption. However exporting (without this flag) is always safe. --encoding UTF-16LE|ASCII When merging (only), you may need to specify the encoding for strings to be used in the hive file. This is explained in detail in "ENCODING STRINGS" in Win::Hivex::Regedit(3). The default is to use UTF-16LE, which should work with recent versions of Windows. --unsafe-printable-strings When exporting (only), assume strings are UTF-16LE and print them as strings instead of hex sequences. Remove the final zero codepoint from strings if present. This is unsafe and does not preserve the fidelity of strings in the original Registry for various reasons: • Assumes the original encoding is UTF-16LE. ASCII strings and strings in other encodings will be corrupted by this transformation. • Assumes that everything which has type 1 or 2 is really a string and that everything else is not a string, but the type field in real Registries is not reliable. • Loses information about whether a zero codepoint followed the string in the Registry or not. This all happens because the Registry itself contains no information about how strings are encoded (see "ENCODING STRINGS" in Win::Hivex::Regedit(3)). You should only use this option for quick hacking and debugging of the Registry contents, and never use it if the output is going to be passed into another program or stored in another Registry.
The program currently supports Windows NT-derived guests starting with Windows XP through to at least Windows 8. The following Registry keys are supported: "HKEY_LOCAL_MACHINE\SAM" "HKEY_LOCAL_MACHINE\SECURITY" "HKEY_LOCAL_MACHINE\SOFTWARE" "HKEY_LOCAL_MACHINE\SYSTEM" "HKEY_USERS\.DEFAULT" "HKEY_USERS\SID" where SID is a Windows User SID (eg. "S-1-5-18"). "HKEY_USERS\користувач" where username is a local user name (this is a libguestfs extension). You can use "HKLM" as a shorthand for "HKEY_LOCAL_MACHINE", and "HKU" for "HKEY_USERS". The literal keys "HKEY_USERS\$SID" and "HKEY_CURRENT_USER" are not supported (there is no "current user"). WINDOWS 8 Windows 8 "fast startup" can prevent virt-win-reg from being able to edit the Registry. See "WINDOWS HIBERNATION AND WINDOWS 8 FAST STARTUP" in guestfs(3).
"virt-win-reg" expects that regedit files have already been reencoded in the local encoding. Usually on Linux hosts, this means UTF-8 with Unix-style line endings. Since Windows regedit files are often in UTF-16LE with Windows-style line endings, you may need to reencode the whole file before or after processing. To reencode a file from Windows format to Linux (before processing it with the --merge option), you would do something like this: iconv -f utf-16le -t utf-8 < win.reg | dos2unix > linux.reg To go in the opposite direction, after exporting and before sending the file to a Windows user, do something like this: unix2dos linux.reg | iconv -f utf-8 -t utf-16le > win.reg For more information about encoding, see Win::Hivex::Regedit(3). If you are unsure about the current encoding, use the file(1) command. Recent versions of Windows regedit.exe produce a UTF-16LE file with Windows-style (CRLF) line endings, like this: $ file software.reg software.reg: Little-endian UTF-16 Unicode text, with very long lines, with CRLF line terminators This file would need conversion before you could --merge it.
Registry keys like "CurrentControlSet" don't really exist in the Windows Registry at the level of the hive file, and therefore you cannot modify these. "CurrentControlSet" is usually an alias for "ControlSet001". In some circumstances it might refer to another control set. The way to find out is to look at the "HKLM\SYSTEM\Select" key: # virt-win-reg WindowsGuest 'HKLM\SYSTEM\Select' [HKEY_LOCAL_MACHINE\SYSTEM\Select] "Current"=dword:00000001 "Default"=dword:00000001 "Failed"=dword:00000000 "LastKnownGood"=dword:00000002 "Current" is the one which Windows will choose when it boots. Similarly, other "Current..." keys in the path may need to be replaced.

Note that some of these tips modify the guest disk image. The guest must be shut off, else you will get disk corruption. RUNNING A BATCH SCRIPT WHEN A USER LOGS IN Prepare a DOS batch script, VBScript or executable. Upload this using guestfish(1). For this example the script is called "test.bat" and it is uploaded into "C:\": guestfish -i -d WindowsGuest upload test.bat /test.bat Prepare a regedit file containing the registry change: cat > test.reg <<'EOF' [HKLM\Software\Microsoft\Windows\CurrentVersion\RunOnce] "Test"="c:\\test.bat" EOF In this example we use the key "RunOnce" which means that the script will run precisely once when the first user logs in. If you want it to run every time a user logs in, replace "RunOnce" with "Run".

First upload the program and optionally the service wrapper. In this case the test program is called "test.exe" and we are using the RHSrvAny wrapper: guestfish -i -d WindowsGuest <<EOF upload rhsrvany.exe /rhsrvany.exe upload test.exe /test.exe EOF Prepare a regedit file containing the registry changes. In this example, the first registry change is needed for the service itself or the service wrapper (if used). The second registry change is only needed because I am using the RHSrvAny service wrapper. cat > service.reg <<'EOF' [HKLM\SYSTEM\ControlSet001\services\RHSrvAny] "Type"=dword:00000010 "Start"=dword:00000002 "ErrorControl"=dword:00000001 "ImagePath"="c:\\rhsrvany.exe" "DisplayName"="RHSrvAny" "ObjectName"="NetworkService" [HKLM\SYSTEM\ControlSet001\services\RHSrvAny\Parameters] "CommandLine"="c:\\test.exe" "PWD"="c:\\Temp" EOF Нотатки: • For use of "ControlSet001" see the section above in this manual page. You may need to adjust this according to the control set that is in use by the guest. • "ObjectName" controls the privileges that the service will have. An alternative is "ObjectName"="LocalSystem" which would be the most privileged account. • For the meaning of the magic numbers, see this Microsoft KB article: http://support.microsoft.com/kb/103000.

Be careful when passing parameters containing "\" (backslash) in the shell. Usually you will have to use 'single quotes' or double backslashes (but not both) to protect them from the shell. Paths and value names are case-insensitive.
