我习惯于把我的任务栏放在屏幕的左边，但是默认windows 10的任务栏，如果靠左，它就会很粗壮，看起来很宽，占用太多的屏幕空间。

有没有办法，让他能瘦一点呢？

有的，参考下面的方法

首先你需要装一个软件：

https://ramensoftware.com/7-taskbar-tweaker

代码开源的：

https://github.com/m417z/7-Taskbar-Tweaker

下载安装之后，设为开机自启动。然后启动软件

点击状态栏图标，右键选择高级设置，找到 no_width_limit 设为1

然后鼠标右键点击任务栏，然后取消任务栏锁定，进入任务栏设置，选择使用小图标。

然后你开始拖拽任务栏，让它往左边缩窄。

直到你满意为止。

然后再锁定任务栏

好了，重启电脑，你的任务栏依然会变得很窄。全部归功于你下载的这个软件taskbar-tweak

摘抄如下

You could use as tool called "Taskbar Tweaker". After a small search I've heard that it works well with Windows 7, 8 and 8.1. I don't know if it is already implement for Windows 10. According to some beta-tester it should work.

so try this:

Install 7+ Taskbar Tweaker.
Right-click on the Tweaker's tray icon, open advanced options and set no_width_limit to 1. Tweaker tray icon
Then use the no_width_limit advanced option. View of Advanced menu.
Install 7+ Taskbar Tweaker and run it. You can close the dialog that is displayed.
Make sure to dock the task-bar to the left edge
Make sure that it is not locked
Make sure that you have selected Use small icons option in the task-bar properties
