Microsoft has decided to block installation of the Windows 10 October 2018 Update on some systems. Computers running corporate security software Morphisec Protector or applications that make use of Morphisec technology will be blocked from installing the latest large Windows 10 update. It’s not the first time Microsoft blocks systems from updating to the Windows 10 October 2018 Update.
Last month, Microsoft withdrew the Windows 10 October 2018 Update after users complained that their files disappeared after installing the update. Then, soon after Microsoft restarted distribution of the update to Windows 10 users again, another issue popped up. Computers running iCloud were blocked from installing the October 2018 Update and Microsoft announced to be working with Apple on a solution. Later, another issue prevented the update to be installed on Windows 10 systems with specific Intel drivers.
Today, the company updated its support page stating it will block some computers from installing the October Update again. Microsoft explains the reason on its website, “Microsoft and Morphisec have identified an issue on devices that have installed Morphisec Protector or another application that uses the Morphisec Software Development Kit (SDK) including: Cisco AMP for Endpoints. These applications may impact customers’ ability to save Microsoft Office documents.”
Microsoft recommends users who want to install the October 2018 Update to temporarily uninstall the affected software and then install an updated version of the software once its available. The company also states it’s working with Morphisec and Cisco on fixing the issue.
