洛阳@双线 在群里提到一个关于OneNote2010的问题。当点击超链接总是提示 “由于本机限制，该操作已被取消，请与系统管理员联系”。
一般，出现这种问题的原因是卸载浏览器所致，如Chrome，Firefox等等。
下面是解决办法，经很多网友试过之后确实可行。
1. 开始，运行，输入”regedit“，确定；
2. 找到 HKEY_CURRENT_USER\Software\Classes\.html；
3. 右击该项，选择”导出“，随后在右侧窗口中右击该键值，选择更改；
4. 将该值更改为“htmlfile”；
5. 如果存在.htm、.xhtm、.xhtml等项，也作相应的修改；
6. 退出，正常使用。
解决办法原文如下：（地址：http://superuser.com/questions/140154/this-operation-has-been-cancelled-due-to-restrictions-in-effect-on-this-computer）
it was caused by uninstalling Chrome. This solved my problem:
if you received this error after uninstalling any application that takes over the HTML open command (including, but not limited to, Chrome & Firefox browsers) you may also need to change the HTM/HTML association in the registry.
- Start, click Run, type Regedit in the Open box, and then click OK.
- Browse to
HKEY_CURRENT_USER\Software\Classes\.html - Right click the value for the .html key and select Modify…
- Change the value from “ChromeHTML” to “htmlfile” (or from FireFoxHTML to htmlfile)
Repeat these steps for htm and .shtml keys if they exist. You may also want to check the xhtml and xhtm keys.
