 Warning C5045 lets you see what patterns in your code cause a Spectre mitigation, such as an LFENCE, to be inserted when the [/Qspectre](../../build/reference/qspectre.md) compiler option is specified. This lets you identify which code files are affected by the security issue. This warning is purely informational: the mitigation is not inserted until you recompile using the **/Qspectre** switch. The functionality of C5045 is independent of the **/Qspectre** switch, so you can use them both in the same compilation.
 
-This warning is new in Visual Studio 2017 version 15.7, and is off by default. Use [/Wall](../../build/reference/compiler-option-warning-level.md) to enable all warnings that are off by default, or __/w__*n*__5038__ to enable C5045 as a level *n* warning. In the IDE, the default warning level is **/W3** and this warning can be enabled in the project **Property Pages** dialog. Open **Configuration Properties** > **C/C++** > **Command Line** and in the **Additional options** box, add */w35045*, then choose **OK**. For more information, see [Compiler warnings that are off by default](../../preprocessor/compiler-warnings-that-are-off-by-default.md). For information on how to disable warnings by compiler version, see [Compiler warnings by compiler version](compiler-warnings-by-compiler-version.md).
