You need to update files in different ways - it all depends on the files themselves. Some are best updated via the Internet, as the application needs regular updates to work correctly (or to ensure the security of the operating system). And some programs do not need to be updated, so the method is different (usually an installer or archive).
Instructions
Step 1
First of all, if you have a Windows operating system, then updating the system files is a very important matter. Because if you have an old version installed, then this can be the cause of system errors, software conflicts and many other problems. Therefore, the update is simply necessary for the correct operation of the applications. Upgrade method at user's choice. “Automatic update” is preferred, because if it is disabled on the system, then you may be missing an important patch for the system. In order to enable automatic updates, you need to go to the address: Start - Control Panel - Automatic Updates. Or, if you are not satisfied with the automatic update, then you can download it on the official Microsoft website (https://www.microsoft.com). If you have a modified version of the operating system, then it is better to download the update from another source. For example, on a site dedicated to your modified version
Step 2
It is advisable to update programs that are constantly in system processes (for example, antivirus) automatically from the Internet, since such applications need to be updated regularly (sometimes several times a day). Long-term failure to update such products can seriously affect the security of the operating system. And updating every time from the site is most likely just inconvenient.
Step 3
If applications that should be updated automatically from the Internet have not received updates for a long time, you need to check everything thoroughly. First of all, go to that program, click on "properties" or "help" and find out the version. Then go to the official website and see which version of the program is the latest. It is likely that the application stopped updating automatically due to the fact that it is an outdated version. In order to receive updates again, you need to download the latest version of the program from the official website.
Step 4
Sometimes the update is not necessary and the program may work correctly without it. But it can add some functions to the program, fix minor bugs, etc. In general, updates of this kind are patches. They are installed quite simply. Usually you need to download the installer, then run and specify the program directory. But sometimes the patch is in the archive and in order to unpack it, you need to install the WinRar program. And then, as a rule, replace the old files from the program directory with new ones from the archives.
