虽然人们总是可以使用我们的Ultimate Windows Tweaker将Windows设置为在每次关机时轻松删除页面文件^{(Page File)}( pagefile.sys )，但您也可以使用Microsoft发布的Fix-It或手动配置注册表设置。^(Registry)每次关机时清理页面文件意味着用零覆盖数据，这需要时间。这会增加关机时间。

但是，如果您处理机密文档，则可能需要“开启”此设置。当您加载此类文档时，它们会被加载到RAM中。为了节省RAM，Windows将某些项目放在页面文件中。因此^(Hence)，在这种情况下，您可能希望在每次关机时删除页面文件。

某些第三方程序可以将未加密（纯文本）密码或其他敏感信息临时存储在内存中。由于Windows虚拟内存体系结构，此信息可以存在于名为pagefile.sys的页面文件中。

尽管清除页面文件不能替代计算机的物理安全性，但您可能希望这样做以在Windows未运行时提高计算机上数据的安全性。

如何在关机时删除PageFile.sys

Windows 11/10中，您可以通过三种简单的方法在关机时清除或删除页面文件^{(Page File)}或分页文件：

终极 Windows 微调器
使用微软修复它
更改注册表设置。

让我们看看细节：

1]终极Windows Tweaker

3 终极 Windows Tweaker 4

下载并使用我们的免费软件Ultimate Windows Tweaker，只需单击一下即可。您将在Customization > File Explorer下看到该设置。

2]使用微软修复它

运行KB314834中提供的此^(KB314834)Microsoft Fix It 可在关机过程中清除Windows页面文件 ( Pagefile.sys )，以便在关机过程完成时页面文件中不包含不安全的数据。

3]更改注册表设置

如果你愿意，你也可以手动清除分页文件！为此，请打开 regedit 并导航到以下键：

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\

右键单击内存管理^{(Memory Management)}并选择New > DWORD (32-bit) Value。
将 DWORD 值命名为ClearPageFileAtShutdown。
双击^{(Double-click)}DWORD值并在数值数据框中键入1。

就是这样！要反转该过程，请在值框中键入 0（零）。

When the Clear virtual memory pagefile setting is turned on, when the system shuts down, the computer may take longer to shut down than it usually takes. This behavior occurs because when this policy setting is turned on, the computer must physically write to each page in the pagefile to clear each page. The period of time that it takes for the system to clear the pagefile varies according to the pagefile size, and the disk hardware that is involved.

希望这可以帮助。

How to delete PageFile.sys at shutdown in Windows 11/10

While one can always use our Ultimate Windows Tweaker tо set Wіndows to delete the Page File (pagefile.sys) on every shutdown easily, you can also use a Fix-It released by Microsoft or configure the Registry setting manually. Cleaning the page-file on every shutdown means overwriting the data by zeros, and it takes time. This will increase the shutdown time.

But if you work on confidential documents, then you may want to have this setting ‘on’. When you load such documents, they are loaded into RAM. To save RAM Windows places certain items in the page file. Hence you may want to delete the page file at every shutdown, in such cases.

Some third-party programs can temporarily store unencrypted (plain-text) passwords or other sensitive information in memory. Because of the Windows virtual memory architecture, this information can be present in the paging file named pagefile.sys.

Although clearing the paging file is not a suitable substitute for the physical security of a computer, you might want to do this to increase the security of data on a computer while Windows is not running.

How to delete PageFile.sys at shutdown

There are three easy ways you may clear or delete the Page File or Paging file at shutdown in Windows 11/10:

Ultimate Windows Tweaker
Use Microsoft Fix It
Change Registry setting.

Let us see the details:

1] Ultimate Windows Tweaker

3 Ultimate Windows Tweaker 4

Download and use our freeware Ultimate Windows Tweaker to do so with a click. You will see the setting under Customization > File Explorer.

2] Use Microsoft Fix It

Running this Microsoft Fix It available at KB314834 clears the Windows paging file (Pagefile.sys) during the shutdown process so that no unsecured data is contained in the paging file when the shutdown process is complete.

3] Change Registry setting

If you want you can also clear the paging file manually! To do so open regedit and navigate to the following key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\

Right-click on Memory Management and select New > DWORD (32-bit) Value.
Name the DWORD value ClearPageFileAtShutdown.
Double-click on the DWORD value and type 1, in the Value data box.

That’s it! To reverse the process, type 0 (zero) in the value box instead.

When the Clear virtual memory pagefile setting is turned on, when the system shuts down, the computer may take longer to shut down than it usually takes. This behavior occurs because when this policy setting is turned on, the computer must physically write to each page in the pagefile to clear each page. The period of time that it takes for the system to clear the pagefile varies according to the pagefile size, and the disk hardware that is involved.

Hope this helps.
