VS2015 about operations such as serious errors in the installation of KB2829760 patches that make it impossible to update and uninstall, etc.

when VS2015 was installed a long time ago, it was not uninstalled cleanly, which caused a problem now. I need to uninstall it, but the prompt during uninstallation is "serious error occurred during KB2829760 installation". Unable to uninstall

first of all, uninstall it directly with the uninstall program of VS in the control panel, and an error occurs. It is guessed that it may be caused by insufficient components

.

so click repair to reinstall VS and then uninstall it, indicating that KB2829760 cannot be uninstalled due to a serious error during installation.
after selecting the first modify button to update the VS2015 component found that there is a part of the installation is not successful or KB2829760
and in the Windows update when I have installed the patch,
think of the patch may have been installed problems, try to uninstall the patch, click on the pop-up VS flag, and then did not respond to the uninstall.
later thought that there may be a problem with the installation package on the original computer, so download the VS2015 installation package again to install, and still prompt that KB2829760 cannot install
and also try to download VS2015 updatess to update KB2829760 installation failed

the following three paragraphs of error are shown in the log file
