There are some issues for software developers using some of the graphics APIs in Vista. Games or programs built solely on the Windows Vista-exclusive version of DirectX, version 10, cannot work on prior versions of Windows, as DirectX 10 is not available for previous Windows versions. Also, games that require the features of D3D9Ex, the updated implementation of DirectX 9 in Windows Vista are also incompatible with previous Windows versions. According to a Microsoft blog, there are three choices for OpenGL implementation on Vista. An application can use the default implementation, which translates OpenGL calls into the Direct3D API and is frozen at OpenGL version 1.4, or an application can use an Installable Client Driver (ICD), which comes in two flavors: legacy and Vista-compatible. A legacy ICD disables the Desktop Window Manager, a Vista-compatible ICD takes advantage of a new API, and is fully compatible with the Desktop Window Manager. At least two primary vendors, ATI and NVIDIA provided full Vista-compatible ICDs. However, hardware overlay is not supported, because it is considered as an obsolete feature in Vista. ATI and NVIDIA strongly recommend using compositing desktop/Framebuffer Objects for same functionality.
If you discover that your license is from MSDN or TechNet, what probably happened is, you bought an MSDN licensed key, which carries up to 10 activations, unlike full packaged retail licenses which only carry 1 activation. The person who sold it to you probably sold it to 10 other people. Somewhere along the way, one of those persons might have installed it on a second system, activated it. Because it went past the 10 activation threshold, Microsoft detected that it was being abused and blocked the key from further use.
I previously had a windows 7 home premium original copy which I did bought spending my money. It worked well. After win 10 launch I could successfully upgrade to windows 10 and the copy got activated automatically. There were talks around saying Microsoft is giving away free windows activation this time. So i made a USB copy of windows 10 PRO in to my flash drive and I DID A CLEAN INSTALL FROM THAT VERY COPY. Now I have Windows 10 PRO not activated. I cannot activate this using my windows 7 home premium product key. PLEASE HELP!
