微信在桌面上不见了怎么办

打开微信—我—账号与安全—绑定QQ号即可，或者下载更新QQ至QQ2011beta4及以上版本即可。
具体如下：
1、微信图标消失不见了，可能的一个原因是，您的微信没有绑定您当前的QQ号码。可能您使用其他QQ登录了微信，或您没有使用当前QQ号注册微信，还有可能您解绑了QQ号。

2、若您没有使用当前QQ号注册微信，则您直接用当前QQ号登录微信即可绑定该QQ号码。若您解绑了QQ号，您需要将QQ与微信进行绑定关联。

3、要实现微信与QQ号的绑定，请执行以下操作：打开微信，将界面定位到“我”选项卡界面。
/iknow-pic.cdn.bcebos.com/d52a2834349b033b59e98e9719ce36d3d539bd1d?x-bce-process=image/quality,q_85"target="_blank"title="点击查看大图">/iknow-pic.cdn.bcebos.com/d52a2834349b033b59e98e9719ce36d3d539bd1d?x-bce-process=image/quality,q_85"target="_blank"title="点击查看大图">/iknow-pic.cdn.bcebos.com/d52a2834349b033b59e98e9719ce36d3d539bd1d?x-bce-process=image/quality,q_85"target="_blank"title="点击查看大图">/iknow-pic.cdn.bcebos.com/d52a2834349b033b59e98e9719ce36d3d539bd1d"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/d52a2834349b033b59e98e9719ce36d3d539bd1d?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/d52a2834349b033b59e98e9719ce36d3d539bd1d"/>
4、选择账号与安全，点击进入。

5、您可以在此界面看看您的QQ号是否为绑定状态，绑定即可。

6、微信图标不显示与QQ客户端版本也有关系，若您的QQ是旧版本，可能就不会显示微信图标。对于这个原因，您可以下载更新QQ至QQ2011beta4及以上版本即可。

微信在桌面消失有两种可能：
1.
微信被卸载，解决方法——重新下载微信；
2.
微信快捷方式被删除，解决方法——进入软件管理，创建快捷方式。
如果是被卸载了，微信之前保存的聊天记录、表情、收藏等会丢失。
