There are several ways to unpack (or install) a patch. Correct installation of the patch is required for the applications to work correctly, since incorrect installation may cause interference in operation.
Instructions
Step 1
The most important patch for the operating system is a software update, since almost every update fixes some kind of bugs. That is why some modern applications refuse to work under Windows XP versions not updated to Service Pack 3. You can update the operating system in different ways. It is better to activate automatic updates via the Internet: Start - Control Panel - Automatic Updates. When errors occur through automatic updates (especially in "modernized" versions of Windows), you need to download the update file manually from the official website of the operating system (https://www.microsoft.com) or other sources specifically for your "upgraded" version
Step 2
The same applies to any applications that are constantly in system processes (for example, antivirus, firewall, browser). It is advisable to specify automatic updates from the Internet in the settings of these programs, since they occur regularly (sometimes several times a day) and it is not very convenient to update manually.
Step 3
There are different ways to install a patch for other software that can work correctly and without it. Most often, the patch is located in the installer. You just need to open the installation file and specify the application directory. It should be noted that if this patch was not downloaded from a trusted / official source, then it is advisable to check it for viruses.
Step 4
Sometimes all patch files are located in an archive (rar, zip or 7z format). In order to unpack them, you need to install the Winrar or 7Zip archiver (better modern versions to support some formats). After unpacking, as a rule, you just need to replace the old files from the directory with new ones from the archive (often instructions are attached to such archives).
