Error number: 0x80070420

I reinstalled Windows XP Home over my existing XP Home installation, but I
used another XP CD because the one I own was unable to be accessed by my CD
drive. I registered the second installation with my original XP's product key
number. Everything works fine but when I use Windows Update I get this error
[Error number: 0x80070420]

Please help me understand what the problem is. Thanks.

type

regsvr32 wuaueng.dll

If you get any error messages, try the same command while in Safe Mode
