Installed CUDA10.0 but now somewhere show the current version is 10.2

Accelerated Computing CUDA CUDA Setup and Installation
1

My OS is WIN10 64BIT HOME.
Early in this year, I installed CUDA 10.0 using the CUDA10.0 setup programe:
cuda_10.0.130_411.31_win10.exe, and the installation was successful.

But somehow, yesterday I noticed that in some places, the CUDA version was shown as 10.2:

  1. (fig.1)Run NVDIA-SMI command, the CUDA version is shown as 10.2.
  2. (fig.2)In NVDIA control panel > system info,
    the product name of NVCUDA.DLL(file version 26.21.14.4219) is also a 10.2-like version called “NVDIA CUDA 10.2.131 driver”.

And in the follwing places, the CUDA version was still shown as 10.0:

  1. (fig.3)In the Windows Control Panel > Programs and Features, the versions of
    CUDA Development,
    CUDA runtime,
    CUDA Documentation,
    CUDA Sample,
    CUDA Visual Studio Integration,
    are all still 10.0.

  2. (fig.4to7)If I run the CUDA10.0 setup programe “cuda_10.0.130_411.31_win10.exe”,
    the programe will check and showed the current versions on my computer of
    CUDA Development,
    CUDA runtime,
    CUDA Documentation,
    CUDA Sample,
    CUDA Visual Studio Integration,
    all still result in 10.0, too.

So,
Which is the actual current CUDA version on my system? 10.0? 10.2?
If it is 10.2, why did this happened? I never run a 10.2 installation, except once I just did some NVDIA driver upgrade in GeforceExperice, I did not notice if there was any CUDA 10.2 update during the driver upgrade process. Is this the possible reason why CUDA changed into 10.2?
