Today is the second Tuesday of the month, and that can only mean one thing: it's Patch Tuesday, or the day where Microsoft releases updates for all supported versions of Windows. In a blog post today, the company noted that it's broadening the range of devices that will receive Spectre and Meltdown mitigations, as it's removing the anti-virus compatibility check.
The Windows 10 cumulative updates that are available today are only for PCs, which is a bit out of character for Patch Tuesday. Usually, phones get some love too; however, last month, Microsoft waited an extra day, so we may see those updates tomorrow.
If you're on the Windows 10 Fall Creators Update, or version 1709, you'll see KB4088776, or build 16299.309. That can be manually downloaded here, and it contains the following fixes:
Addresses issue where Internet Explorer stops working when using F12-based developer tools.
Addresses issue with printing XML documents with Internet Explorer and Microsoft Edge.
Updates legacy Document Mode cell visibility in Internet Explorer.
Addresses issue with pinch and zoom gestures on some hardware in Internet Explorer.
Addresses issue where Internet Explorer is unresponsive in certain scenarios when a Browser Helper Object is installed.

Addresses issue where, after installing KB4056892,KB4073291, KB4058258, KB4077675, or KB4074588 on a server, you may not be able to access SMB shared files in directory junction points or volume mount points hosted on that server. The error is "ERROR_INVALID_REPARSE_DATA”. As a result, editing some group policies using GPMC or AGPM 4.0 may fail with the error "The data present in the reparse point buffer is invalid. (Exception from HRESULT: 0x80071128)".
Addresses issue where an AD FS server issue causes the WID AD FS database to become unusable after a restart. This might prevent the AD FS service from starting.
Addresses issue where, after installing KB4090913, the Mixed Reality Portal may fail to initialize. This results in an “SXXXXXXX-X” error or a “We couldn’t download the Windows Mixed Reality Software” message may appear after the software is successfully downloaded.

As usual, you don't actually have to manually download and install any of these. If you head over to Settings -> Update & security -> Windows Update -> Check for update, it will automatically download and install the cumulative update that corresponds to your version of Windows 10.
