Get Product Key from my Recovery partition

Hello All
I had got some virun problem in my HP laptop so that I use a recovery partition in order to install Windows 7, but unfortunately during installtion the system stucked and I think my recovery partition is also corrupt. Now I want to install Windows 7 without using recovery partition and want to use my own Windows OEM key but the question is that how can I get my Windows 7 product key from my recovery partition, actually the sticker on the bottom of my laptop wipe out as well as I cannot run keyfinder program because I couldn't login into my Windows. Is there any possibilities that I can get my product key from my recovery partition. Thanks

Regards

Muzokh

You can't run a keyfinder program unless Windows is booted up to desktop. Did you burn your recovery cds?

And I assume that you didn't make a system image backup.

You are out of luck.

The key is heavily encrypted and cannot be read without the OS being booted.

Have you tried running Recovery again from boot? HP Recover Windows 7 Operating System Using HP Recovery - HP Customer Care (United States - English)

If it fails try marking the Recovery partition Active, then reboot to see if Recovery starts, or try the Fkey again. Partition - Mark as Active (Method Two)

If these all fail then order your Recovery disks from HP tech support which will restore the PC to factory condition. You may need to wipe the HD first with Diskpart Clean Command to get them to run.

It can, Greg if it is an installed o/s - even if not booted.

However if he is trying to get the key from a .wim file (which he probably is ) - then you are right - I don't know how to do that directly.

Hi Si

What program can read the key from boot disk or another OS? We need it.

Maybe we can help him force Recovery to run, mount it to scan for key or run it ?

Greg,
If one has a running Win 7 system,
then one could read in the registry hive, extract the reg entry, alter this script and then simply in PowerShell run this function:

Script:

function Get-ProductKey {    
    
$map="BCDFGHJKMPQRTVWXY2346789" 
    
$value = (get-itemproperty "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion").digitalproductid[0x34..0x42]  
    
$ProductKey ""  
    
for ($i 24$i -ge 0$i--) { 
      
$r 
      
for ($j 14$j -ge 0$j--) { 
        
$r = ($r 256) -bxor $value[$j
        
$value[$j] = [math]::Floor([double]($r/24)) 
        
$r $r 24 
      
$ProductKey $map[$r] + $ProductKey 
      
if (($i 5) -eq 0 -and $i -ne 0) { $ProductKey "-" $ProductKey }
 } 
    
$ProductKey
