系统运维
最近3d vdi 用户反馈，windows 10从v1803升级到v1809后，进入3d vdi后鼠标指针丢失，但是功能还是可以用的。又是一个蛋疼的问题。查了citrix官网，已经是citrix known issue了，而且在windows 10 v1809上也很多其它的known issue。具体请参考citrix官网：https://support.citrix.com/article/ctx234973
目前citrix官网说正在working with microsoft解决这个问题，给出了一个workaround，具体信息见下：
issue 7 – issue description
mouse pointer is not visible within a v1809 hdx 3d pro session. all operations inside the session are to be performed by keyboard using shortcuts. this issue is seen with citrix xenapp/xendesktop 7.15 only. this issue is not seen with later versions of xenapp/xendesktop.

problem cause
a change in mouse functionality api\\\’s is causing this issue.
solution
citrix is working with microsoft to resolve this issue. as a work around, users could enable mouse pointer trails by following below steps:
click start and type \\\’mouse settings\\\’.
click on \\\’additional mouse options\\\’.
click on \\\’pointer options\\\’ tab.
select the checkbox \\\’display pointer trails\\\’.
click apply and ok.
作为运维人员要么自己帮客户改，要么给客户一个文档，让客户自己改。但是应该还有option3：组策略更改这个配置，google了一下，确实有这个注册表键值。
注册表键值路径：hey_current_user\\\\control panel\\\\ mouse
然后新建一个string value，命名为：mousetrails
填写一个键值，键值范围是：1 ~ 7
1 – minimum length trails.
4 – medium length trails.
7 – maximum length trails.
如果想关闭显示指针轨迹，把这个值设置为0即可。
