如何在电脑上打开pdf文档


在win10系统的电脑上是可以直接打开PDF格式文档来查看的。
把PDF文件拖放到电脑中的edge浏览器上,就可以使用这个浏览器打开PDF文件来浏览的。
也可以安装第三方的PDF阅读器来使用的。

电脑开关机慢是什么原因,怎么解决


“鼠标右键点击此电脑,选择属性,控制面板主页,点击硬件和声音,电源选项下方的更改电源按钮的功能,选择更改当前不可用的设置,将启动快速启动取消,保存修改。”这样子试试看行不行。
其实电脑开关机慢影响因素很多,还有可能是其他以下原因:
(1)内存不足:如果以前进入速度不慢,现在变慢,且有两条内存的话,有可能是某条内存出现故障,进入系统后检查内存容量是否与原配置一致,如果减少了则查出损坏内存并替换;如果以前也慢,则可能是内存不足,需要添加与原内存同品牌同型号内存或直接替换为大容量内存。
(2)网络连接故障:如果网络设置出现问题,可能导致系统自动搜索IP地址速度变慢,也会影响开机速度。如果这样,则需要检查并确保网络设置都能正常使用,并将本地连接设置为固定的静态IP地址。
(3)硬盘出现碎片或坏道:建议使用启动U盘启动电脑,在PE系统下使用专用工具如DISKGEN对硬盘进行检测和修复,如果坏道过多,修复无效则需要更换硬盘。
(4)开机通电自检时间过长:需要在开机时快速连按DEL键(笔记本为F2或其它热键)进入CMOS设置菜单,将机箱内部没有安装的设备检测关闭。
希望对您有所帮助。

microsoft .net framework 2.0安装不了


经查证,win xp pro和home版本有可能会出现此问题,除会发生以上现象外,当您尝试在“控制面板”中打开“管理工具”时,可能不会执行任何操作。

问题的原因在于注册表设置不正确

解决方法:
1. 开始-运行-键入 regedit-回车。
2. 找到以下注册表项:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders
3. 在“注册表编辑器”的右窗格中,双击常见管理工具。
4. 在“数值数据”框中,键入以下行,然后单击确定:
%ALLUSERSPROFILE%\Start Menu\Programs\Administrative Tools
5. 在文件菜单上,单击退出以退出注册表编辑器。
6. 重启电脑。

如果以上办法无效活着在你的系统上找不到对应注册表键值时,把以下所有内容复制到文本文档,保存为注册表文件*.reg,双击导入。
