For openssl update, you can get the update in https://wiki.openssl.org/index.php/Binaries (see "OpenSSL for Windows")
[   ] openssl-1.0.1s-i386-win32.zip        2016-12-01 05:04  960K  
[   ] openssl-1.0.1s-x64_86-win64.zip      2016-12-01 05:04  1.0M  
      https://indy.fulgan.com/SSL/
Win32 OpenSSL v1.1.0c

For cipher update, use iiscrypto which is a GUI for disabling the SChannel registry value for SSLv2 nor SSLv3 and enable the TLS1.0 above .
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 3.0]

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 3.0\Server]
"Enabled"=dword:00000000
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 2.0]

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 2.0\Server]
"Enabled"=dword:00000000

(e.g Apply FIPS 140-2 settings -> Disables SSLv3 and older... make sure not to disable TLS 1.0 or might lose RDP with default settings.)
