Here's what you need to to in order to set your Windows Updates to be able to check them before installing:
Go to your Start Menu.
Select "All Programs"
Under All Programs Select Windows Updates
Click on Windows Update
Once in Windows Update on the left you will see "Change Settings"
Click on "Change Settings"
Under Important Updates there is a menu
Select "Check for updates but let me decide whether to download and install them."
This will set your preferences so you can review all your Windows updates before they install.
Because you say you don't want to add anything to your computer, you'll need to manually check for the optional mislabeled updates MS is sending through more and more often now to attempt to install Windows 10 to your computer. The Windows Update numbers to check for on Windows 7 are: KB....5583, 2664, and/or 1917. If you have Windows 8, KB....2543 is the one you need to check for (last four digits of each). If one or more of those appears in your Updates, you need to hide the file(s) by right clicking on it and selecting "Hide File". That will keep it from installing until MS decides to send it/them through again. This is happening more and more often as the July deadline for the free Windows 10 approaches. You will now be notified of your Windows Updates in your Notifications area (lower right corner)
The GWX Control Program is the one I'm using successfully (and posted a thread about "FIX" in Electronics) and it automatically cleans whatever MS may have loaded to a computer relevant to Windows 10 and then continually blocks those Updates going forward so you don't have to concern yourself with them.
I do understand your hesitation so you can handle it either way. HTH's
