As we hit the second Tuesday of the month, Microsoft is once again rolling out updates to every supported version of Windows. That, of course, includes Windows 11, but also a handful of Windows 10 versions that are still supported for the foreseeable future. Most notable Windows 10 versions 21H2, 21H1, and 20H2 are getting updated to build 19044.1526, 19023.1526, and 19042.1526, respectively.

These versions of Windows 10 all have the same bits, so they all get the same update, which is labeled KB5010342. If you're interested, you can download it manually here. There isn't much that's specifically new to Windows 10 build 19044.1526 (and related builds) with only a small fix being mentioned:

  • Addresses an issue that causes a Lightweight Directory Access Protocol (LDAP) modify operation to fail if the operation contains the SamAccountName and UserAccountControl attributes. The error message is, “Error: 0x20EF. The directory service encountered an unknown failure”.

However, this update does also include a handful of changes that were in the optional update for January. That includes a reminder for those still using Internet Explorer 11 that it will soon be retired, being replaced by IE mode in the new Microsoft Edge browser. You can check out the full list of fixes included in that update below:

While Windows 10 versions 21H2, 21H1, and 20H2 are the only ones supported for general consumers, there are some older versions of Windows 10 that are only supported in business settings. Those are all getting updated as well, and you can find more information about those updates using the table below:

You can download any of today's updates manually, but because they're mandatory, they'll eventually install by themselves. That's always the case with Patch Tuesday updates, and we'd recommend installing them if you want to have the best experience - though it's not all that uncommon for new updates to also have some problems.
