Windows 2000/XP/2003计算机中所自带了Windows Messenger 4.7,但是现在我们大多是用新版本的MSN进行这些功能，可能很多朋友就会觉得没必要留着它，那么我们就可以将它删除！
为了删除干净，首先我们需要把与它有关的程序关闭,比如IE、OE等。然后打开“开始”-“运行”在里面输入“RunDll32 advpack.dll,LaunchINFSection %windir%\INF\msmsgs.inf,BLC.Remove”(注：不包括引号)然后最好重新启动一下计算机就可以顺利删除！
删除完毕后如果还需要装回它，请再到Windows Update中检查更新，就会在“软件，可选”的列表中看见Windows Messenger
用过飞信的朋友可能会因为有多个帐号烦恼，因为只能在电脑上打开一个飞信，曾经有很多用户询问移动官方，都被告知不能实现。但其实是支持的，现在我们可以通过小修改在电脑上打开多个窗口：
1、打开飞信的安装目录，找到Client.config文件，一般在C:/Program Files/China Mobile/Fetion/Client.config
2、用记事本打开，内容如下：
<?xml version="1.0" encoding="utf-8"?>
<ImpsConfiguration>
<AppSettings>
<add key="BuildDate" value="2008-5-27 12:43:17" />
<add key="LinkType" value="DotNetVM" />
<add key="Version" value="3.3.0599" />
</AppSettings>
</ImpsConfiguration>
3、在三个<add key=*****>后面增加下面的这行：
<add key="SingleInstance" value="false"/>
4、也就是这样：
<?xml version="1.0" encoding="utf-8"?>
<ImpsConfiguration>
<AppSettings>
<add key="BuildDate" value="2008-5-27 12:43:17" />
<add key="LinkType" value="DotNetVM" />
<add key="Version" value="3.3.0599" />
<add key="SingleInstance" value="false"/>
</AppSettings>
</ImpsConfiguration>
保存！现在你就可以在电脑上打开多个飞信了！。
用过QQ一段时间的人大概都知道，QQ好友中的排名其实是有规律的。会员排在最前面，然后根据名字ASCII码来进行排序，所以很多人在名称前面加一些特殊符号来提高自己的位置。在这里告诉大家一个方法，不用改名，就让你的QQ排名到最前面，甚至可以超过红名的会员QQ用户。
首先需要你的QQ是2007正式版及以上版本，然后在“更新状态”中选择 “Q我吧”在线状态，只要设置成“Q我吧”状态，你的QQ在好友里是排在第一位的，而且在所有会员QQ号前面。如果你想跟别人聊天的话，就选择“Q我吧”状态，别人就很容易找到你。
★小提示：如果QQ采用了“Q我吧”在线状态，而且您有加入群的话，在群里面名字一样会靠前，超过了管理员和群主的位置。
很多朋友都看到我QQ里有两个自己而羡慕不已（一个是QQ软件自动显示的另一个则是好友状态，号码完全一样），其实要加自己为好友是非常简单的，只要执行以下步骤即可。
第一步.进入个人设置（在QQ面板上直接点自己的头像即可进入）点身份验证和状态然后点身份验证”，勾选“允许任何人把我列为好友”。如果你的QQ已经是这样的设置，那么请跳过。
第二步.点击“黑名单”左边绿色箭头，展开黑名单列表（如果没有人在里面，就是空白的），在黑名单三个字上点右键选择“添加坏人名单”。提示出现“敲入坏人QQ号”，在输入框里输入自己的QQ号码，完成后按回车。系统会提示你“确实要删除好友吗”点“确定”。
第三步.这时你就可以看到黑名单里有自己的号码了，然后将它拖入到我的好友里，就可以在我的好友里看到它了。嘿嘿。怎么样够简单吧，赶快在朋友面前炫耀一下吧！

今天下午回来后，我试着要登入我的MSN，没想到怎样都进不去，也显示了"80048821"这个错误代码。我试着上网搜寻解决办法，但是没有一个解决得了我的问题，尤其是在许多解答下面，也看到很多网友的回应亦表示情况依旧没有改善。于是，我开始很紧张，尤其是处于网路无所不在的病毒及骇客所造成的风险环境下，让我不禁担心起帐号被盗用的可能性。
不过，终究我还是靠自己冰雪聪明的脑袋解决了这问题（哪有人这样夸自己的XD）。为了造福遇到相同问题的捧尤们，所以我决定将我的发现分享给大家！
MSN登入时的错误代码"80048821"，是表示你的帐号或密码出了问题。这问题的出现，其中一个可能性是在你设定帐号或上一次修改密码时，勾选了"将密码设定每隔72天就过期"这个选项，于是72天的期限一到，密码就无效，需要重新设置。
解决方法如下：
1.用浏览器开启MSN的首页http://cn.msn.com/
2.按MSN首页右上方的"登陆"
3.接着进入登入的页面，MSN会请你打上你的帐号（有时候已经显示在那了）、原本的密码，下方还有请你输入新密码的选项。这时候就打上你的帐号、原本的密码、自己想要设定的新密码，接着就能够顺利登入啰！
这是我解决MSN错误代码"80048821"的方式，只是我不确定是否每个人出现这错误代码时的情况都相同，但如果你和我一样，在网路搜寻过的方法都无效，又不想要重新申请一个新帐号，就试试这方法吧！
Windows Live Messenger Error 80048821
SYMPTOMS
Windows Live Messenger could not sign you in because the sign-in name you entered does not exist or your password is incorrect. Error code: 80048823
SOLUTION
Before you start. Did you enter correct Username and Password?
1. The date on your computer needs to be set properly. Double click the clock verify that the time and date are set.
2. If your password information is not saved, verify that you are typing it in with the correct case (uppercase or lowercase).
3. Change your password at http://passport.com to something smaller (under 10-12 characters), then try signing in again.
4. If you use a firewall (like ZoneAlarm, Norton Internet Security etc.), it's possible that Messenger doesn't have the correct rights to access the Internet, especially since you upgraded. You may need to re/add Messenger to the allowed list of programs in your firewall if this is the case.
5. If you disabled your firewall in the past, it still may be blocking Messenger. Try restarting it and see if that helps the situation. You also might try uninstalling an installed firewall, to verify that it isn't causing a problem (even if it is disabled).
6. Clear your IE cache and cookies. Open Internet Explorer, click the Tools menu, then Internet Options, then click the Delete Files button, and when that's complete click the Delete Cookies button.
7. Check your IE Security settings. Open Internet Explorer, click the Tools menu, then Internet Options, then Advanced tab, scroll to the Security section, and verify that "Check for server certificate revocation" is unchecked. Also verify that 'Use SSL 2.0' and Use SSL 3.0' is checked, then click OK.
8. Click Start, then Run, and enter the following:
regsvr32 softpub.dll
then click OK
and do the same for the following:
regsvr32 wintrust.dll
regsvr32 initpki.dll
9. If using MSN Messenger 7, click the Tools menu, then Options, then Connection category, click the Advanced Settings button, uncheck all the options, click OK twice and then try again.
