Step 4: Install Windows Vista SP2 in Clean Boot Mode
=========================================
Please disable all startup items and third party services when booting to avoid conflict when installing Windows Vista SP2.
1. Click "Start", type: MSCONFIG in the search box and press Enter.
Note: Please click "Continue" if the "User Account Control" window pops up.
2. Click "Services", check the "Hide All Microsoft Services" box and click "Disable All" (if it is not gray).
3. Click "Startup", click "Disable All", click "OK" and restart the computer.
Note: Temporarily disabling the Startup Group only prevents the startup programs from loading at startup. This shouldn't affect the system or other programs. We can manually run these programs later.
4. Please double click the downloaded Standalone Installer and follow the instructions to install Windows Vista SP2.
To restore the computer to use a Normal Startup, repeat step 1 above. Then click "Normal Startup" on the General tab, click "OK", and then restart the computer.
