Windows 7: Windows 7 sp1 update error 8024200D and 8007000d

since the past 2 weeks i have been trying to install windows 7 sp1. When i use automatic updates sp 1 gets downloaded properly but while insalling i get the error 8024200D. I have used the system update readiness tool and microsoft fix it. Still the same error.



Here are the problems that i could find in CBS log
SPI: (SPIRegQueryDWORDValue:400)Failed to open the registry root: n/a, key: SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\ServicePack\SP1. er=0x2.

After i could not resolve this problem i decided to download and run the standalone installer of sp1. Then i got the error 8007000d while downloading windows6.1-KB976932-X86.cab.


I also tried installing in both ways in clean boot with all services except microsoft disabled. Still the same error. PLz someone help me.

And i want to know if sp1 will be required to run upcoming and latest games??
