Question: Standard corporate environment, forcing clients to got through a proxy server via a proxypac. In the OSX configuration is in the following format:

```
http://www.proxy.server.name:8080/proxy_pac_path_to_package.pac

```

Trying to connect via CLI, for a homebrew install, and used (so far) the following options:

```
export http_proxy=http://www.proxy.server.name:8080/proxy_pac_path_to_package.pac

export http_proxy=http://www.proxy.server.name:8080

export http_proxy=http://myusername:mypasswd@www.proxy.server.name:8080/proxy_pac_path_to_package.pac

export http_proxy=http://myusername:mypasswd@www.proxy.server.name:8080

```

with mypasswd special characters being mapped into their hex code, and with username using either the "simple" form, or the entire AD path, or the email, etc.

None of the above worked. Any idea about what I may be missing, from one's own experience through non-obvious things?

Answer: 
This isn't a solution for you, unfortunately. I have the same issue and haven't been able to find a solution, hack, or fix anywhere. I ended up rolling back to Windows 10 Pro version 1511 and selecting the "defer upgrades" option in *Updates*, *Advanced Options*, to put off receiving upgrades for as long as possible with the hope that these bugs will be worked out by the time Microsoft forces the upgrade on us. Note that this is only available in the Pro version. Doing this does not prevent any security updates. I wish I could be of more help.
I know it's an old thread, but I've just had the same issue, and I figured a way around it, thought this might help.... 

open windows explorer and browse to the following directory: 

C:\Users\*name\*\AppData\Roaming\Microsoft\Windows\Libraries

There you will see all your libraries, right click each on of them, click on properties, then to the tab (Library), from "optimize this library for" option choose "pictures" instead of "general items" this should make all libraries the same view as "pictures" view thumbnail. 

if you desire something aside from the thumbnails, same steps apply, only now you would have to browse to a random folder, also optimize it for pictures, and enter it, then set up the view settings you like, and from folder options >> view >> apply to all folders, this will make all folders with optimization for pictures use the same view for example. 

I hope this helps.
