Microsoft .NET Framework 4.5.2, 4.6, and 4.6.1 will end support in April 2022

Microsoft Windows users who have Microsoft .NET version 4.5.2, 4.6, or 4.6.1 installed must install a newer version of the Microsoft Framework if they want Microsoft to support the framework through future product updates.

According to Microsoft, all three frameworks will end support on April 26, 2022. After the support date ends, the product will not receive "security fixes or technical support."

Most home devices are kept up to date through Windows Update. These devices already have newer versions of the framework installed, such as .NET Framework 4.8.

Devices that are not automatically updated may need to be manually updated to move from one of the unsupported versions to a supported version.

System administrators can update their installed Microsoft .NET Framework version to a newer version, at least Microsoft .NET Framework 4.6.2, before April to continue receiving support and security updates. Version 4.6.2 of the framework comes pre-installed on Windows 10 version 1607. Newer versions of Windows 10 include newer versions of the framework, for example, Windows 10 version 1903 includes .NET Framework version 4.8 by default.

.NET Framework 4.6.2 and later follows the operating system's lifecycle policy; this means that it will lose support when the operating system loses support.

The three .NET versions that will end support in April 2022 are affected by Microsoft's decision to retire SHA-1 in the company's products.

Microsoft is making this change because the .NET Framework previously used certificates that use Secure Hash Algorithm 1 (SHA-1) for digital signing, and we are prioritizing support for newer digital certificates.

Check the installed .NET Framework version

You may be wondering which versions of .NET Framework are installed on your Windows device. It's relatively easy to find, as you can check it in the registry by:

1. Open Start, type regedit.exe, and select Windows Registry Editor from the list of results.
2. Confirm UAC prompt.
3. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP. On Windows 10 and above, you can paste a path into the address field to jump directly to it.
4. Check the version folder starting with v and the client or full folder. The registry string value version displays the installed .NET Framework version.

If you see that one of the listed frameworks will lose support, you may want to consider upgrading it so that your device supports that framework.
