> regedit /e --- Exports the entire registry to a file. You can modify this command to add a filename and specific location on the drive, such as regedit /e c:\AllRegistryEntries.reg. You can export a specific key with the following example command regedit /e keybackup.reg HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Edge.

Windows regedit executes in the background, and reg, regtool save use 
Windows binary reg file formats, and regedit /e and reg export save as 
utf16le using hex for strings - use Cygwin regtool list -v instead for 
readable strings e.g.

	$ regtool list -v \\HKEY_CURRENT_USER\\Environment\\
	$ regtool list -v /HKEY_CURRENT_USER/Environment/
	$ regtool list -v /proc/registry/HKEY_CURRENT_USER/Environment/
	$ regtool list -v //hostname/HKEY_CURRENT_USER/Environment/
	$ regtool list -v hostname:/HKEY_CURRENT_USER/Environment/
