Setup instructions:
These instructions only applies under the WU-Release. If you chose the Default-Release you have to do configure it correctly first.

Note: The proxy itself must be installed in your host, not in the machine which needs to have a working Windows Update !

Common instructions:
Because Windows 2000 and Windows XP uses old algorithms, you have to allow Java to use them as they were disabled for security reasons.

1. Navigate to the folder where your Java runtime is installed (Something like C:\Program Files\Java\jre1.8.0_xxx)
2. Once you found this folder, navigate to lib and then security.
3. Do a backup of the file java.security (You can call it something like java.security.bak)
4. Open java.security with a text editor in administrator mode
5. Go find the line jdk.tls.disabledAlgorithms=...........
6. Replace it so it is exactly only jdk.tls.disabledAlgorithms=

At the end, it should look like that:
