Unable to install Service Pack 1

[lance430]

First i've tried in Windows Update but download is stuck to 0% then i tried manually by using the stand alone KB976932 still didn't work.. It keeps freezing at 50% even after installing System Update Readiness Tool and clean boot.. I tried many times nothing happened and it gives random freezes.

Hi lance430, welcome to the Forum.

Make sure your Anti Virus software is disabled, then refer to this MS website for additional checks & possible solutions.

As Ranger4 suggested, Temporarily disable Anti-Virus until next reboot
& Disable Windows Update Service
Start ORB type cmd
Right-click CMD, choose run as administrator (Elevated Command Prompt (ECP))
