LastPass Free Tier Changes
According to the company’s blog post, the company says, “Starting March 16th, 2021, LastPass Free will only include access on unlimited devices of one type.” The post continues to explain that starting today you will have to set your active device type. You’ll get three chances to decide on which you want to use as your “active device type” (mobile or desktop). However, note that your devices sync automatically. That means “you’ll never lose access to anything stored in your Vault or be locked out of your account due to these changes,” according to the support article.

Microsoft released out-of-band non-security updates for Windows 10 Versions 1909 and 2004 as well as versions 1803 and 1809 for enterprise/education.  The purpose of the updates is to fix the issue causing blue screens (BSOD) when printing to network printers with Type 3 printer drivers.  The issue showed up after installing the March 2021 cumulative updates.

Because the updates are optional, they are not available via Windows update.  However, if you have been affected by this issue, the updates can be downloaded manually from the Microsoft Catalog:

Support for Microsoft Edge legacy ends today, March 9, 2021, and will no longer receive future security updates. 

The Microsoft Edge Legacy desktop application will be removed and replaced with the new Microsoft Edge if you install the optional Windows 10 March Preview ("C") release or next month when the Windows 10 cumulative monthly security updates released on April 13, 2021 are installed for the following Windows 10 versions:

  • Windows 10, version 1803, all editions (April 2018)
    • Note: This version will not be included in the optional Windows 10 March Preview release.
  • Windows 10, version 1809, all editions (October 2018)
  • Windows 10, version 1903, all editions (May 2019)
    • Note: This version is out of support for desktop
  • Windows 10, version 1909, all editions (October 2019)
  • Windows 10, version 2004, all editions (May 2020)
  • Windows 10, version 20H2, all editions (October 2020)
    • Because Windows 10, 20H2 already uses the new Microsoft Edge as its default browser, it will not be reinstalled; only Microsoft Edge Legacy will be removed.
When the April 13 update is installed or you install the optional Windows 10 March Preview ("C") release, the out of support Microsoft Edge Legacy desktop application will be removed and the new Microsoft Edge will be installed.
