Deleted registry Key, now windows won't boot

Hi all,
I followed some bad advice and deleted the following key from my XP registry


now my machine will not boot, it just gets to the blue login screen, but instead of having my login icon, has a small windows xp icon. Exactly the same in safe mode.

How can I restore this key, can I do it from recovery console? Will a windows repair, restore it?

I really, really need to not risk losing any data.

Thanks in advance

Hi RedKelvin,

>> How can I restore this key, can I do it from recovery console?

Yes. Or, even easier is to use BartPE boot CD. If you have System Restore enabled in the subject computer, you can recover the SOFTWARE hive from one of the System Restore points.

Create a BartPE Boot CD (See: http://www.nu2.nu/pebuilder/)
Boot the system with the Bart's CD.

Get into the System Volume Information folder located in the drive where Windows is installed. Then, open a sub-folder that was not created at the current time. You may have to click Details on the View menu to see when these folders were created. There may be one or more folders starting with "RPx under this folder. These are restore points.

Open one of these folders to locate a Snapshot subfolder. The following path is an example of a folder path to the Snapshot folder:
C:\System Volume Information\_restore{D86480E3-73EF-47BC-A0EB-A81BE6EE3ED8}\RP1\Snapshot

From the Snapshot folder, copy the following file to the following location:



Rename the file named "SOFTWARE" to "OLD_SOFTWARE"

I attempted many things, but in the end all I could do was rebuild the hive,
