Registry values may contain backslashes in their names, but doing so makes them difficult to distinguish from their key paths when using some legacy Windows Registry API functions . When introduced with Windows 3.1, the Windows Registry primarily stored configuration information for COM-based components. It is not a requirement for Windows applications to use the Windows Registry. For example, .NET Framework applications use XML files for configuration, while portable applications usually keep their configuration files with their executables. Actually, the normal behaviour is for Windows 10 to disable creating restore points after it does an Upgrade.
