What is the purpose of Windows Update?

Ok, thank you all

Yes, but if we already have a security software on our computer, do we have to install the update?

hi
virus and crashes if you don't do the updates

There will be no viruses or crashes if we don't do the updates. You just need to update your antivirus manually. Otherwise, all the Windows updates are useless except for slowing down your computer. Personally, I have blocked everything and the PC has been running like new for a year.

Yes, he is right, it’s useless except for taking up space on your PC. Plus, I’ve noticed that since you do the updates, the PC crashes very often and reinstalling Windows is a hassle, plus you lose everything you have on your hard drive!

So yes, Windows Update updates are not really that useful, although some fixes are worth it and it's better to carry them out. After that, it's better to be knowledgeable in the field to choose your own appropriate fixes. And then, it's a big fake that formatting deletes any data as long as you choose the option to keep an "Old" file during formatting. Once formatted, you can go to "C:" and you will see a "windows old" folder where you will find all your images, videos, programs, and personal information, text files, etc. So, the result is that if you master your formatting, you won't lose any personal data x)
