Your results for Spectre makes me suspect the ability of the InSpectre tool. Meltdown requires an OS patch which Microsoft has provided for Windows OSs including versions 7, 8, and 10. The Windows update for Meltdown was released in late January/early February.
Spectre variant 2 requires a microcode update which Intel has released to OEMs. Up to this point the microcode update requires an updated BIOS. If you do not have an updated BIOS then I don't see how you are protected against Spectre. There is a article here: https://arstechnica.com/gadgets/2018/03/microsoft-will-soon-start-shipping-the-intel-spectre-microco..., that indicates Spectre microcode fixes are coming to a Windows update but as far as I know that has not happened yet.
