今天不知道做了什么操作，win10桌面和工具栏上的字体变得非常大，但正文的字体是正常的。于是上网搜索解决方法：
- 在“设置”->“显示”中设置了100%显示比例仍然不好用，原来就是100%。
- 百度上搜索到的设置显示字体大小的解决方法全部都不好用，那些设置选项都是win7下的，win10下根本就找不到。
- 按照某篇文章的方法，设置自定义放大比例为100%，没有效果（有的人可能会有效果，不过我这里没有）。
- 按照微软网站上相关问题的回复，更新驱动，没有效果，链接就不放了，反正没效果。
解决方法
最后在谷歌中搜索相关的英文关键字，终于找到一个解决方法，修改注册表。如下：
把下面的注册表配置信息复制到一个文本文件中，保存为扩展名.reg的文件，右键选择“合并”，把配置导入注册表，然后重启，即可恢复默认的字体设置。

这个方法对我是有效的，但不保证其他人遇到同样的问题也会有效，毕竟问题产生的原因是多种多样的，不能指望一种药包治百病。这里贴出来，只是希望给大家多一种解决问题的方法。
