About this tag
Build 9841 is an early Windows Technical Preview build that users encountered during the Windows 10 development cycle. Discussions on this tag focus on compatibility issues with third-party antivirus software like McAfee, where users reported problems after upgrading to later builds and had to revert to build 9841 to restore Windows Firewall and Defender functionality. Another recurring topic is the Windows Update settings in build 9841, which required registry edits to change update behavior, a limitation that was later addressed in subsequent builds. The tag also references the initial release of the Windows 9 Technical Preview in October, with build 9841 being a key milestone featuring the Start Menu and modern UI elements.
