  • New cumulative update KB 4491113 for IE in Win7 and 8.1 fixes the backslash bug

    Microsoft broke IE’s behavior earlier this month. With the update released yesterday, it’s fixed… but under odd circumstances.

    Here’s the bigger picture.

    This month’s Patch Tuesday patches for Win7 and 8.1 contained this weird, acknowledged, bug:

    After installing this update, Internet Explorer may fail to load images with a backslash (\) in their relative source path.

    That bug, and several others, were fixed in this week’s Monthly Rollup preview patches – but those aren’t distributed through normal channels. You have to wait until next month, when the Monthly Rollup Preview patches will (presumably) be added to the March Monthly Rollups.

    Here’s where things get weird. On Feb. 19, Microsoft released a Cumulative update for Internet Explorer: February 19, 2019, a silver bullet patch with the sole intent:

    This cumulative update includes improvements and fixes for Internet Explorer 11 that is running on Windows 8.1 or Windows 7, and resolves the following issue:

    Internet Explorer cannot load images that have a backslash (\) in their relative sources path.

    So we have a cumulative update, KB 4491113, that fixes a bug introduced in this month’s Monthly Rollups, but which is also fixed in this month’s Monthly Rollup previews. The previews fix other bugs as well, but I guess this one was problematic enough to warrant a single silver bullet.
