篇一：WIN7修改电脑时间提示没有权限的解决方法
在windows7系统下，用户想要修改电脑时间，我们可通过右下角时间区域进行调整，在win8和win10系统下我们可通过自动同步来校正网络时间，不过有部分用户向小编反映，在win7系统下修改时间，系统提示没有修改权限，那么对于该问题我们应该如何解决呢?下面看小编为大家带来的解决方案!
操作方法
1.首先，我们同时按下win7下载电脑键盘上的win+R快捷键打开电脑的运行窗口，在打开的运行窗口中，我们输入gpedit.msc并单击回车，这样，我们就可以打开win7下载电脑的组策略编辑器窗口了。
2.在打开的组策略编辑器窗口中，我们依次点击展开左侧菜单中的Windows设置-安全设置-本地策略-用户权限分配，接下来，我们在用户权限分配的右侧窗口中找到更改系统时间选项。
3. 接下来，我们双击打开更改系统时间对话框，然后再点击添加用户或组，在打开的新窗口上，我们点击高级按钮，即会打开选择用户或组，输入要添加权限的账户名，再点击确定按钮保存。完成之后，我们重启一下自己的win7电脑就可以了。
通过上述方法我们就能够解决win7系统无法修改时间，并出现没有权限的故障了， 对于该问题解决方法还是比较简单的，用户只需要根据上述教程来操作即可!
篇二：为什么电脑上时间不能改
为什么电脑上时间不能改

在对电脑系统时间进行“自动与Internet时间服务器同步”的时候，一点击“立即更新”，就会出现提示：“RPC服务器不可用”。一般而言，出现这种情况主要有以下几种原因和解决办法：
1.RPC服务没有启动
“开始”--〉“设置”--〉“控制面板”找到“管理工具”--〉“服务”，找到“Remote Procedure Call (RPC)”，双击打开，在“启动类型”里选择“自动”后，点击确定；找到“Remote Procedure Call (RPC) Locator”，双击打开，在“启动类型”里选择“自动”后，点击确定；最后重新启动电脑后，按照正确的方法再安装一遍软件即可解决问题。 另外，如果您的系统是xp，在重新启动安装之前，“开始”——》“运行”，运行msconfig，选择的是“正常启动”，则就会加载所有服务，包括rpc服务；选择是“有选择的启动”，您必须选中“加载系统服务”一项保证服务启动时加载。如果不行，就继续下面操作。
2、控制面板——管理工具——服务——WINDOWS TIME——启动，再试试就行了。如果还是不行，请继续下面操纵。
3、服务里的windows time服务没有启动，可以在服务里手动启动；
或者在运行里输入cmd回车打开命令提示符，在命令提示符状态下输入w32tm /register，
如果显示成功，继续输入net start "windows time"，开启完毕就可以同步时间了。
附另外两种常见问题解决方案：
一、与服务器进行同步时间出错
windows time 服务是打开状态，但点击“自动更新”时还是显示“Windows在与服务器进行同步时出错”，怎么回事？
解决办法：
1.双击右下角的时间；
2.把服务器改成210.72.145.44（中科院国家授时中心的服务器） ；
3.修改之后，一定记得要先点右下角的“应用”，再点“自动更新”就可以了，一般不会出错！即使是高峰时期，三次之内必成功，比美国的服务器好多了。
二、自由选择时间同步间隔：
系统默认的时间同步间隔只是7天，我们无法自由选择，使得这个功能在灵活性方面大打折扣。其实，我们也可以通过修改注册表来手动修改它的自动同步间隔。
1. 在“开始”菜单→“运行”项下输入“Regedit”进入注册表编辑器；
2. 展开
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time
\TimeProviders\NtpClient ] 分支，并双击 SpecialPollInterval 键值，将对话框中的“基数栏”选择到“十进制”上；
3. 而这时在对话框中显示的数字正是自动对时的间隔(以秒为单位)，比如默认的604800就是由7(天)×24(时)×60(分)×60(秒)计算来的，看 明白了吧，如果您想让XP以多长时间自动对时，只要按这个公式算出具体的秒数，再填进去就好了。比如我填了3天，就是259200。
篇三：Win7时区和时间不能更改的解决
Win7时区和时间不能更改的解决
前段时间，不知道怎么把电脑折腾的不让更改日期时间和时区了，研究了半天，结合网上的知识，终于搞定，原因为电脑的时区信息丢失，把下面的内容保存为reg文件，双击导入注册表，即可修复丢失的时区，之后即可更改时区和日期时间。
或者运行下面的注册表文件，也行
