It is one of the most terrible WU issues as I've ever met.
As far as I know many times this happend with other issues with WinSxS/CBS too,theoretically sometimes is possible to fix this terrible issue but not always (apart mentioned repair installation,but becuase it is laptop from HP it is impossible to apply for you)
Upgrading to Windows 7 require at least Vista SP1
So if you decide to attempt to fight with this error please follow below
with administrative previlliges (right click on cmd.exe as admin) and type: cd /d C:\Windows\WinSxS
dir /s /b >%userprofile%\Desktop\log.txt
on your desktop appear log.txt file
2.Make sure you have this key: HKLM\Software\Microsoft\Windows\CurrentVersion\Component Based Servicing\Version
if yes please export this key from the registry and save it under any name and show it us here.
3.Find CBS.log file
All files: log.txt, exported HKLM\...\Version key and CBS.log please attache to post or upload on rapidshare.com
