Cumulative updates are usually released on a monthly basis, with the exact date and time depending on your time zone. Microsoft releases updates on the second Tuesday of each month, known as Patch Tuesday. However, the company may also release updates on other days if a serious security vulnerability is discovered or if there is a critical bug that needs to be fixed.
How to check for cumulative updates?
To check for cumulative updates, you need to go to the Windows Update settings. You can access these settings by opening Control Panel and clicking on the Windows Update option.

The .NET framework version 3.5 and earlier versions did not provide support for applications to use Transport Layer Security (TLS) System Default Versions as a cryptographic protocol. This update enables the use of TLS v1.2 in the .NET Framework 3.5.
The following registry keys can be set to use the operating system defaults for SSL and TLS instead of the hardcoded .NET Framework defaults for a managed application running on the computer.
- For 64-bit operating systems:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v2.0.50727] "SystemDefaultTlsVersions"=dword:00000001 [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v2.0.50727] "SystemDefaultTlsVersions"=dword:00000001
- For 32-bit operating systems:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v2.0.50727] "SystemDefaultTlsVersions"=dword:00000001
Note If the application has set the ServicePointManager.SecureProtocol in code or through config files to a specific value, or uses the SslStream.AuthenticateAs* APIs to specify a specific SslProtocols enum, the registry setting behavior does not occur.
In addition, we have added the SslProtocolsExtensions enumeration that you can use as an option for setting TLS v1.2, TLS v1.1, as well as operating system defaults for the ServicePointManager.SecurityProtocol property when targeting .NET framework version 2.0 SP2. (See the Developer Guidance section for the information on how to use the extensions.)
For more information about how to enable TLS v1.1 or v1.2 as operating system defaults, follow the instructions at https://technet.microsoft.com/en-us/library/dn786418(v=ws.11).aspx#BKMK_SchannelTR_TLS12.
