Detecting Windows 10 Version: Cross-Platform and Version-Inclusive
In modern software development, detecting Windows 10 version across different platforms and versions, including Windows 7 and above, is crucial for cross-platform compatibility and accessing version-specific features. However, relying on Windows-specific functions like IsWindows10OrGreater() poses challenges when targeting Windows versions prior to Windows 10.
The Multi-Version Alternative
To overcome these limitations, a robust multi-version solution is necessary. RtlGetVersion provides a reliable method to retrieve the genuine OS version, bypassing compatibility shims that can often return inaccurate information. This function can be accessed through either the DDK or runtime dynamic linking as shown below:
<code class="C++">RTL_OSVERSIONINFOW GetRealOSVersion() {
HMODULE hMod = ::GetModuleHandleW(L"ntdll.dll");
if (hMod) {
RtlGetVersionPtr fxPtr = (RtlGetVersionPtr)::GetProcAddress(hMod, "RtlGetVersion");
if (fxPtr != nullptr) {
RTL_OSVERSIONINFOW rovi = { 0 };
rovi.dwOSVersionInfoSize = sizeof(rovi);
if ( STATUS_SUCCESS == fxPtr(&rovi) ) {
return rovi;
}
}
}
RTL_OSVERSIONINFOW rovi = { 0 };
return rovi;
}</code>
Additional Considerations
For enhanced details, the RTL_OSVERSIONINFOEXW structure can be utilized instead of RTL_OSVERSIONINFOW, ensuring the appropriate setting of the dwOSVersionInfoSize member. This approach delivers precise results for Windows 10, regardless of the presence or absence of a manifest.
Feature-Based Approach
Beyond Windows version detection, a feature-based approach is often regarded as a superior alternative. By targeting specific features rather than OS versions, applications can accommodate a wider range of system configurations and ensure optimal performance across different environments.

C Polymorphism : is function overloading a kind of polymorphism?
Jun 20, 2025 am 12:05 AM
Yes, function overloading is a polymorphic form in C, specifically compile-time polymorphism. 1. Function overload allows multiple functions with the same name but different parameter lists. 2. The compiler decides which function to call at compile time based on the provided parameters. 3. Unlike runtime polymorphism, function overloading has no extra overhead at runtime, and is simple to implement but less flexible.
What Are the Different Kinds of Polymorphism in C ? Explained
Jun 20, 2025 am 12:08 AM
C has two main polymorphic types: compile-time polymorphism and run-time polymorphism. 1. Compilation-time polymorphism is implemented through function overloading and templates, providing high efficiency but may lead to code bloating. 2. Runtime polymorphism is implemented through virtual functions and inheritance, providing flexibility but performance overhead.
C : Is Polymorphism really useful?
Jun 20, 2025 am 12:01 AM
Yes, polymorphisms in C are very useful. 1) It provides flexibility to allow easy addition of new types; 2) promotes code reuse and reduces duplication; 3) simplifies maintenance, making the code easier to expand and adapt to changes. Despite performance and memory management challenges, its advantages are particularly significant in complex systems.

C tutorial for people who know Python
Jul 01, 2025 am 01:11 AM
People who study Python transfer to C The most direct confusion is: Why can't you write like Python? Because C, although the syntax is more complex, provides underlying control capabilities and performance advantages. 1. In terms of syntax structure, C uses curly braces {} instead of indentation to organize code blocks, and variable types must be explicitly declared; 2. In terms of type system and memory management, C does not have an automatic garbage collection mechanism, and needs to manually manage memory and pay attention to releasing resources. RAII technology can assist resource management; 3. In functions and class definitions, C needs to explicitly access modifiers, constructors and destructors, and supports advanced functions such as operator overloading; 4. In terms of standard libraries, STL provides powerful containers and algorithms, but needs to adapt to generic programming ideas; 5
Polymorphism in C : A Comprehensive Guide with Examples
Jun 21, 2025 am 12:11 AM
Polymorphisms in C are divided into runtime polymorphisms and compile-time polymorphisms. 1. Runtime polymorphism is implemented through virtual functions, allowing the correct method to be called dynamically at runtime. 2. Compilation-time polymorphism is implemented through function overloading and templates, providing higher performance and flexibility.
