Today is the second Tuesday of April, and with it, Microsoft is once again releasing new updates for all supported versions of Windows, including Windows 10, Windows 8.1, and Windows 7 - as long as you're a business paying for extended security updates.

As usual, there are two types of updates for both Windows 8.1 and Windows 7, as well as their server counterparts - a monthly rollup that's usually installed automatically and a security-only update that you have to install manually.

Starting with Windows 8.1, the monthly rollup update is KB5001382 and you can download it manually here. It includes the following changes:

  • Addresses a time zone change for Volgograd, Russia from UTC+4 to UTC+3 Moscow Standard Time (MSK).
  • Addresses a time zone change for The Republic of South Sudan from UTC+3 to UTC+2 Juba. For more information about this change, see KB 4601275.
  • Addresses an issue with security vulnerabilities identified by a security researcher. Because of these security vulnerabilities, this and all future Windows updates will no longer contain the RemoteFX vGPU feature. For more information about the vulnerability and its removal, see CVE-2020-1036 and KB4570006. Secure vGPU alternatives are available using Discrete Device Assignment (DDA) in Windows Server LTSC releases (Windows Server 2016 and Windows Server 2019) and Windows Server SAC releases (Windows Server, version 1803 and later versions).
  • Addresses an issue that prevents you from specifying up to 255 columns when you use the Jet Text installable indexed sequential access method (IISAM) format.
  • Security updates to Windows Input and Composition, Windows Fundamentals, Windows Hybrid Cloud Networking, Windows Kernel, and Windows Media.

There's nothing new in terms of known issues, but the one we've been saying for a while now is still here:

Symptom Workaround
Certain operations, such as rename, that you perform on files or folders that are on a Cluster Shared Volume (CSV) may fail with the error, “STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5)”. This occurs when you perform the operation on a CSV owner node from a process that doesn’t have administrator privilege.

Do one of the following:

  • Perform the operation from a process that has administrator privilege.
  • Perform the operation from a node that doesn’t have CSV ownership.

Microsoft is working on a resolution and will provide an update in an upcoming release.

As for the security-only update, that's labeled KB5001393 and you can download it manually here. It only includes the following:

  • Addresses a time zone change for Volgograd, Russia from UTC+4 to UTC+3 Moscow Standard Time (MSK).
  • Addresses a time zone change for The Republic of South Sudan from UTC+3 to UTC+2 Juba. For more information about this change, see KB 4601275.
  • Security updates to Windows Input and Composition, Windows Fundamentals, Windows Hybrid Cloud Networking, Windows Kernel, and Windows Media.

It has the same known issue as the monthly rollup.

Moving on to Windows 7, the monthly rollup update is KB5001335 and you can download it manually here. It includes the following changes:

  • Addresses a time zone change for Volgograd, Russia from UTC+4 to UTC+3 Moscow Standard Time (MSK).
  • Addresses a time zone change for The Republic of South Sudan from UTC+3 to UTC+2 Juba. For more information about this change, see KB 4601275.
  • Addresses an issue with security vulnerabilities identified by a security researcher. Because of these security vulnerabilities, this and all future Windows updates will no longer contain the RemoteFX vGPU feature. For more information about the vulnerability and its removal, see CVE-2020-1036 and KB4570006. Secure vGPU alternatives are available using Discrete Device Assignment (DDA) in Windows Server LTSC releases (Windows Server 2016 and Windows Server 2019) and Windows Server SAC releases (Windows Server, version 1803 and later versions).
  • Addresses an issue that prevents you from specifying up to 255 columns when you use the Jet Text installable indexed sequential access method (IISAM) format.
  • Addresses an issue if you monitor for these events, Windows Backup will not report a successful Event ID 14 or backup finished Event ID 4 after you apply update KB4561643 or KB4556843.
  • Security updates to Windows Apps, Windows Hybrid Cloud Networking, Windows Kernel, and Windows Media.

It has the same known issue as the updates above.

Finally, the security-only update for Windows 7 is KB5001392 and you can download it manually here. It also has the same known issue as the other updates, and includes these changes:

  • Addresses a time zone change for Volgograd, Russia from UTC+4 to UTC+3 Moscow Standard Time (MSK).
  • Addresses a time zone change for The Republic of South Sudan from UTC+3 to UTC+2 Juba. For more information about this change, see KB 4601275.
  • Security updates to Windows Apps, Windows Hybrid Cloud Networking, and Windows Media.

As a reminder, only select users are eligible to get updates for Windows 7, since it's no longer supported for the general public. Also, as mentioned at the start, the monthly rollup updates will generally install automatically over time, but you can install them manually if you prefer. The security-only updates can only be installed manually using the links above.
