Are Windows Updates really necessary?
Well, this is interesting. Nowadays, Windows can prompt you to restart your computer practically anytime during your work, to finish the installation of some Windows update that has been downloaded in the background. How come that, when constant internet connection was less ubiquitous than now, especially in the 90’s, Windows practically never needed update and still managed to remain functional for years and did not crash?
It looks like that the perpetual Windows update is a solution to a problem that was somehow generated by the way Windows Update works. First of all, when most computers were offline, the vulnerability of a PC was the floppy disk drive, where viruses could make their way into the computer and cause harm. These viruses didn’t even require Windows to run; they were happily cause damage in MS-DOS.
And then, when Windows became a real operating system rather than a graphical add-on to DOS, this meant a new way for viruses to spread. And then Microsoft started to issue updates, and patch the vulnerabilities they have discovered. These updates were distributed on CD-ROMs, and then went online. But in the meantime, hackers became smarter too, and by reverse-engineering these security updates they started to try to find out the vulnerability the Windows update was meant to fix.
The timeline drafted above is of course vague and missing a few milestones in between, but the point is that Windows updates are really necessary, because in many occasions Windows Update itself gives an idea to a hacker to exploit an unpatched vulnerability. Therefore, no matter how annoying it might be, you should always let Windows Update to perform the installation and stay ahead of attackers.
Old drivers harm system performance and make your PC vulnerable to errors and crashes.
