If there have been issues with Windows updates since 2004, my surfing has been unaffected by it. Sure there are times after an update where my computer seems a wee-bit slower. But that always seems to be temporary and usually fixed by another update soon after the last one.
I trust Windows Updates and I trust good antivirus programs like ESET. I have more important uses for my time, rather then looking for trouble where trouble doesn't exist in the first place.
For instance/example:
If your subdivision has never had a home invasion or car stolen, then I won't be the first to install an outdoor security system, then come home and view / fast-forward the day's event outdoors.
I have never encountered a reason why I must spy on my latest update at another website, before loading it on my own computer.
If your computer settings are correct and you don't visit the sleazeball websites, plus your antivirus/malware...etc.... are loaded and upper-shelf in quality, I don't see the need for spying on Windows updates.
