KB4284835 was published with just a single known issue, as Microsoft said that “some users running Windows 10 version 1803 may receive an error ‘An invalid argument was supplied’ when accessing files or running programs from a shared folder using the SMBv1 protocol.”

But as it turns out, this isn’t the only problem in this update, as the company has updated the official KB page with info to state that Microsoft Edge browser could also hit glitches after installing June 2018 patches.
