IMPORTANTVerify that****you have installed the required updates listed in theHow to get this update section before installing this update. Customers who have purchased the Extended Security Update (ESU) for on-premises versions of this OS must follow the procedures in KB4522133 to continue receiving security updates after extended support ends on January 14, 2020. For more information about ESU and which editions are supported, see KB4497181.
Because ESU is available as a separate SKU for each of the years in which they are offered (2020, 2021, and 2022)—and because ESU can only be purchased in specific 12-month periods—you must purchase the second year of ESU coverage separately and activate a new key on each applicable device for your devices to continue receiving security updates in 2021.
If your organization did not purchase the first year of ESU coverage, you must purchase both Year 1 and Year 2 ESU for your applicable Windows 7 or Windows Server devices before you install and activate the Year 2 MAK keys to receive updates. The steps to install, activate, and deploy ESUs are the same for first and second year coverage. For more information, see Obtaining Extended Security Updates for eligible Windows devices for the Volume Licensing process and Purchasing Windows 7 ESUs as a Cloud Solution Provider for the CSP process. For embedded devices, contact your original equipment manufacturer (OEM).
This security update includes improvements and fixes that were a part of update KB4598288 (released January 12, 2021) and addresses the following issues:
