Open Control panel (click the right button of your mouse at the lower left of you display monitor or LCD, e.g., at the Windows logo. and then you can see control panel menu)
Click "Windows update"
In left you can see "Change settings"
Change the setting into "Check for updates but let me choose whether to download and install them". It is usually set automatic.
Reboot
The Windows module installer workers cannot bother you anymore.
Important:
Because Windows update is set manual, you MUST check regularly (weekly or monthly) windows update by yourself.
