+1. Download Visual Studio ([Visual Studio download](https://visualstudio.microsoft.com/downloads/)).
+When you install Visual Studio, also install related packages:
+   - under `Workloads`, select `Desktop development with C++` 
+(select `C++ CMake tools for Windows` in this workload) and `.NET desktop development`.
+   - under `Individual components`, search `Libs for Spectre` and select `MSVC v143 - VS 
+2022 C++ x64/x86 Spectre-mitigated libs(Latest)`.
+
+2. Download and install SDK ([windows-sdk](https://developer.microsoft.com/en-us/windows/downloads/windows-sdk/))
+
+3. Download and install WDK ([windows-wdk](https://learn.microsoft.com/en-us/windows-hardware/drivers/download-the-wdk)). Please select `Install Windows Driver Kit Visual Studio extension` when you install WDK.
+
+4. Open **a terminal in Visual Studio**, then go to `src\WinMSRDriver`, and run the following command to compile the driver. Then you will see `MSR.sys` in `src\WinMSRDriver\x64\Release`.
+    ```
+    MSBuild.exe MSR.vcxproj -property:Configuration=Release -property:Platform=x64

+## Known limitations
 
 Running PCM.exe under Cygwin shell is possible, but due to incompatibilities of signals/events handling between Windows and Cygwin, the PCM may not cleanup PMU configuration after Ctrl+C or Ctrl+Break pressed. The subsequent run of PCM will require to do PMU configuration reset, so adding -r command line option to PCM will be required.
