Vista fast user switching disappeared

My fast user switching option in Vista Home machine suddenly disappeared. I remember it was there, then it was not. I don't know why this happened, but here is how to fix it.

A rough translation:

Run regexit.exe
Go to HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows > CurrentVersion > Policies > System
Look for a key named HideFastUserSwitching. If it exists, change it's value to 0 (zero). If it does not exist create it as a DWORD and set it to zero.
You might need to log off before the change takes effect.

utf8 and hebrew in tomcat

In tomcat 5.0 and above, if your UTF-8 request parameters are received as gibberish you might need to do the following:

In your server.xml add the URIEncoding="UTF-8" and useBodyEncodingForURI="true" to the Connector tag(s):


redirectPort="8443" />

This should make GET requests work properly.

For some reason the above does not work for POST requests. If you ask the tomcat people they'll mumble something about W3C, RFC, and RTFM. The short way to have this work for POST requests is to write a small filter to set the request encoding properly. We are using something similar to this:

package com.realcommerce.filters;
import javax.servlet.*;
public class RequestEncodingFilter implements Filter {
public void init(FilterConfig filterConfig) throws ServletException {
//Do Nothing
public void destroy() {
//Do Nothing
public void doFilter(ServletRequest request,ServletResponse response,
FilterChain chain) throws IOException, ServletException
chain.doFilter(request, response);

This made POST requests pass Hebrew (or any UTF-8) parameters properly.
