0patch does not replace executable files or modify them in any way. It corrects them only in memory, which can be done without relaunching them. //

• quickly fix "0days" and unpatched vulnerabilities,
• micropatch end-of-life and unsupported products (such as Office 2010 or Java runtime),
• provide patches for legacy OSes and applications (such as Windows 7, Server 2008 R2),
• patch what’s exploited in the wild,
• fix vulnerable 3rd party components and customized software.
