Microsoft has retracted its August Windows 8.1 Patch Tuesday update after users reported crashes and problems restarting their systems.

One reported bug impacted fonts and where they are installed, as well as how they are rendered, according to Microsoft. Another caused systems to crash with a ‘0x50 Stop error message.’

The company revised the affected update’s bulletin to reflect potential issues.

Users who have already downloaded the problematic fix can remedy it through Microsoft’s instructions, which were posted online.

Microsoft’s August Patch Tuesday shipped nine fixes for 37 bugs and addressed issues in Internet Explorer, in addition to other security issues. This is the first Patch Tuesday update to address problems with Windows 8.1.
