Last week Microsoft officially launched its November update. Unlike prior releases, however, this one was merely looking to more apply some minor cosmetic changes rather than tampering with anything significant within the operating system. That doesn't, of course, mean that it doesn't have people worried. Let's be honest, Windows 10 updates don't have the best track record. In a report
via ComputerWorld, however, it seems that if you have been keeping up-to-date with all of the Windows 10 patches, the download file isn't going to cause you too many downloading issues. Why? Well, in certain circumstances the file may be as small as just 180kb. The November Update file is (essentially) merely the activation for features previously downloaded but not yet ‘turned on' from prior updates. As such, if you're already on the most update to date version of Windows 10, the November update will only be a tiny download file that, essentially, unlocks the door. If you do have 1903 installed but not the most recent cumulative update, then even then the download is only 330MB (and possibly less).
In other words, the only people looking at a reasonably substantial download (circa 3.5GB) are those still using versions prior to 1903.
