KB4499164 install issues

Microsoft recently released security update KB4499164 to Windows 7 Service Pack 1 and Windows Server 2008 R2 Service Pack 1 PCs. The patch aims to prevent Wannacry-style malware attacks.

Windows 7 users who tried to install KB4499164 are experiencing some issues on their systems. For example, on user reported that this update fails to install on Windows 7 systems even after multiple attempts.

More specifically, the patch failed to install with the error 80073701.

I just keep getting Failed to install after it all downloads fine, creates restore point, and goes to ‘installing’… failed, error 80073701.

Apparently, Windows 7 user tried every possible solution ranging from restarting their systems, using Windows Update troubleshooter, disabling the antivirus program and clearing the SoftwareDistribution folder.

However, it seems that this weird installation issue is not going away. On top of that, many users are also unable to install the standalone .msu file for KB4499164.

Another user ran into some major issues after installing KB4499164. He said:

It (seems at least) install correctly but when PC restart PC is unusable. WiFi works, but icon freeze with searching circle. Windows restore do not work.[…]  Then i wanted to shut down the PC but it locks saying the Shut down music was preventing the PC to shut down and was impossible to force the closure of the program.

As mentioned earlier, Microsoft released this patch to fix a critical vulnerability in Windows 7. If you ran into similar update install issues, let us know in the comments below.
