如果您遇到此问题，您可以尝试以下我们推荐的解决方案（不分先后顺序），看看是否有助于解决问题。

1. 运行蓝屏在线疑难解答^{(Blue Screen Online Troubleshooter)}
2. 运行 CHKDSK
3. 运行 SFC 扫描
4. 运行 DISM 扫描
5. 执行系统还原
6. 修复 Windows 安装。

让我们看一下关于列出的每个解决方案所涉及的过程的描述。

如果能正常登录就好了；否则，您必须 启动进入安全模式^{(boot into Safe Mode)}，进入 高级启动选项屏幕^{(Advanced Startup options screen)}，或 使用安装媒体启动^{(use the Installation Media to boot)} 才能执行这些说明。

1]运行^(Run)蓝屏在线疑难解答^{(Blue Screen Online Troubleshooter)}

对于每个BSOD错误，您的第一道防线是运行Microsoft的蓝屏在线疑难解答。在更多情况下，向导将能够解决问题。

2]运行CHKDSK

在这里，您可以运行 CHKDSK^{(run CHKDSK)}并查看问题是否会得到解决。

3]运行SFC扫描

如果有损坏的系统文件，您可能会遇到此问题。此解决方案要求您运行 SFC 扫描并查看是否有帮助。

4]运行DISM扫描

这是Windows 10操作系统的另一个本机工具，可用于修复系统文件损坏以及Windows映像。由于已知这些文件中的损坏会导致蓝屏错误，因此您可以运行 DISM 扫描^{(run DISM scan)}并查看是否有帮助。

5]执行系统还原

如果最近开始出现此BSOD错误，则完全有可能是您的系统最近经历的更改导致了该问题。

如果您不知道发生了什么变化，您可以使用系统还原^{(System Restore)}（任何更改，如应用程序安装、用户首选项以及在还原点之后所做的任何其他内容都将丢失）恢复到您确定设备正常工作的日期.

要执行系统还原^{(perform System Restore)}，请执行以下操作：

• 按Windows key + R调用“运行”对话框。
• 在“运行”对话框中，键入rstrui 并按 Enter 以打开“ 系统还原^{(System Restore)} 向导”。
• 到达System Restore的初始屏幕后，单击Next前进到下一个窗口。
• 在下一个屏幕上，首先选中与Show more restore points关联的框。
• 完成此操作后，选择一个日期早于您第一次开始注意到错误的日期的点。
• 单击下一步^(Next) 前进到下一个菜单。
• 单击完成^(Finish) 并在最后的提示处确认。

在下一次系统启动时，您的旧计算机状态将被强制执行。

6]修复Windows安装

修复 Windows 10 安装^{(Repairing the Windows 10 installation)}应该是您尝试修复此EFS FATAL ERROR 蓝屏错误^{(EFS FATAL ERROR Blue Screen error)}的最后一个选项。

希望这可以帮助！

Fix EFS FATAL ERROR Blue Screen error on Windows 10

One of the numerous Blue Screen of Death errors Windows 10 users might encounter on their device is EFS_FATAL_ERROR. The error bug check has a value of 0x000001D7. It indicates that an EFS (Encrypting File System) error condition has occurred such that cannot be handled without data loss or data corruption. In this post, we will provide the most suitable solutions you can try to successfully resolve the issue.

EFS_FATAL_ERROR Blue Screen error

If you’re faced with this issue, you can try our recommended solutions below in no particular order and see if that helps to resolve the issue.

1. Run the Blue Screen Online Troubleshooter
2. Run CHKDSK
3. Run SFC scan
4. Run DISM scan
5. Perform System Restore
6. Repair Windows installation.

Let’s take a look at the description of the process involved concerning each of the listed solutions.

If you can log in normally, good; else you will have to boot into Safe Mode, enter Advanced Startup options screen, or use the Installation Media to boot to be able to carry out these instructions.

1] Run the Blue Screen Online Troubleshooter

Your first line of action with every BSOD error is to run the Blue Screen Online Troubleshooter from Microsoft. In more cases than not, the wizard will be able to fix the issue.

2] Run CHKDSK

Here, you can run CHKDSK and see if the issue will be resolved.

3] Run SFC scan

If there are corrupt system files, you might encounter this issue. This solution requires you run SFC scan and see if that helps.

4] Run DISM scan

This is another native tool for the Windows 10 operating system which can be used to fix system file corruption as well as Windows image. Since corruption in these files is known to cause blue screen errors, you can run DISM scan and see if that helps.

5] Perform System Restore

If this BSOD error started to occur recently, it’s entirely possible that the issue was facilitated by a change that your system has gone through recently.

If you have no idea what changed, you can use System Restore (any changes like application install, user preferences and anything else made after the restore point will be lost) to revert to a date where you’re certain that your device was working properly.

To perform System Restore, do the following:

• Press Windows key + R to invoke the Run dialog.
• In the Run dialog box, type rstrui and hit Enter to open up the System Restore Wizard.
• Once you arrive at the initial screen of System Restore, click Next to advance to the next window.
• At the next screen, start by checking the box associated with Show more restore points.
• After you’ve done this, select a point that has an older date than the one in which you first started to notice the error.
• Click Next to advance to the next menu.
• Click Finish and confirm at the final prompt.

At the next system startup, your older computer state will be enforced.

6] Repair Windows installation

Repairing the Windows 10 installation should be the last option in your attempt to fix this EFS FATAL ERROR Blue Screen error.

Hope this helps!
