Accepted Answer

Exporting the whole registry to a single .reg file is not so easy, but you can use the `Reg.exe` utility that is installed with Windows to export a chosen root key.

Documentation for `Reg.exe` can be found here.

For example, to save each of the valid root keys (and all sub-keys) to their own files, you could do this:

```
ECHO OFF
reg export HKLM hklm.reg > nul
reg export HKCU hkcu.reg > nul
reg export HKCR hkcr.reg > nul
reg export HKU  hku.reg > nul
reg export HKCC hkcc.reg > nul
```

There is also a `save` option, that does a similar thing but stores the data in a different format.
