即使在检查了所有要求之后，您在安装适用于Linux的^(Linux)Windows 子系统^{(Windows Subsystem)}时也可能会遇到问题。例如，当您尝试从Microsoft Store启动^{(Microsoft Store)}Ubuntu时，您的计算机上可能会出现一条错误消息，显示WslRegisterDistribution failed with error: 0xc03a001a。启动Ubuntu时会出现错误，提示操作由于虚拟磁盘系统限制而无法完成。错误消息还要求解压缩和加密消息。

WslRegisterDistribution失败并出现错误：0xc03a001a
错误：0xc03a001a
由于虚拟磁盘系统限制，请求的操作无法完成。
虚拟硬盘文件必须是未压缩和未加密的，并且不能是稀疏的。

WslRegisterDistribution失败并出现错误：0xc03a001a

错误：0xc03a001a 通常后跟一条消息，内容为，由于虚拟磁盘系统限制，请求的操作无法完成。  虚拟硬盘^{(Virtual hard disk)}文件必须是未压缩和未加密的，并且不能是稀疏的。

在官方GitHub论坛上建议了两种解决问题的方法。第一个允许您禁用加密，第二个负责压缩问题。

• 运行 FSUTIL 命令
• ^{(Uncheck Compress Contents)}取消选中Ubuntu目录的压缩内容

fsutil 工具^{(fsutil tool)}与FAT和NTFS文件系统操作相关，例如管理、准备或卸载卷。

所以基本上，这个问题可以通过以下步骤来解决。

1. 导航到以下USERPROFILE路径CanonicalGroupLimited.Ubuntu。
2. 打开Linux发行版的配置文件文件夹。
3. LocalState 文件夹。
4. 右键单击此文件夹并选择属性。
5. 点击高级按钮。
6. 取消选择压缩^{(Deselect Compress)}内容以节省磁盘空间。
7. 取消选择加密^{(Deselect Encrypt)}内容以保护数据。
8. 仅选择此文件夹选项。

让我们详细看一下步骤。

运行 FSUTIL 命令

打开运行^(Run)提示符 ( Win +R )，键入 cmd，然后按Shift + Enter以管理员权限启动命令提示符。键入并执行以下命令

fsutil behavior set disableencryption 1
fsutil behavior set disablecompression 1

完成后重新启动^(Reboot)计算机，然后启动Ubuntu或任何其他Linux风格。

^{(Uncheck Compress Contents)}取消选中Ubuntu目录的压缩内容

Ubuntu目录位于以下路径

%localappdata%PackagesCanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc

可能是Windows 更新^{(Windows Update)}为该文件夹启用了压缩和加密。如果是这样，那么您需要禁用它

转到%localappdata%Packages，右键单击该CanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc  文件夹，然后选择“属性”。

在“常规^(General)”选项卡下，单击“高级^(Advanced)”按钮。取消选中压缩和加密复选框。单击^(Click)并保存更改。该过程可能需要一些时间，具体取决于文件夹和文件的大小。

当系统提示您仅将更改应用于当前文件夹或所有子文件夹和文件时，请仅选择此文件夹^{(just this folder)}，因为您只是清除压缩标志。

在此之后，更改wsl --set-version命令应该可以工作并允许您运行Linux环境，包括大多数命令行工具、实用程序和应用程序。

此后^(Hereafter)，您的问题应该得到解决，并且您应该不会再看到WSL错误 0xc03a001a，Microsoft说。

Hope it helps!

WslRegisterDistribution failed with error 0xc03a001a

Even after getting аll the requirements checked, you may experienсe issues while installing the Windows Subsystem for Linux. For instance, when you try to launch Ubuntu from the Microsoft Store, аn error message may apрear on your computer reading, WslRegisterDistribution failed with error: 0xc03a001a. The error occurs when launching Ubuntu, where it says the operation could not complete due to a virtual disk system limitation. The error message also asks to uncompress and encrypt the message.

WslRegisterDistribution failed with error: 0xc03a001a
Error: 0xc03a001a
The requested operation could not be completed due to a virtual disk system limitation.
Virtual hard disk files must be uncompressed and unencrypted and must not be sparse.

WslRegisterDistribution failed with error: 0xc03a001a

Error: 0xc03a001a is usually followed by a message that reads, the requested operation could not be completed due to a virtual disk system limitation.  Virtual hard disk files must be uncompressed and unencrypted and must not be sparse.

There are two methods suggested to fix the problem on the official GitHub forums. The first allows you to disable encryption, and the second takes care of the compression issue.

• Run FSUTIL Command
• Uncheck Compress Contents for Ubuntu directory

The fsutil tool is related to FAT and NTFS file system operations such as managing, preparing, or dismounting the volume.

So basically, this problem can be fixed by following the steps below.

1. Navigate to the following USERPROFILE path CanonicalGroupLimited.Ubuntu.
2. Open the profile folder for your Linux distribution.
3. LocalState folder.
4. Right-click this folder and choose Properties.
5. Hit the Advanced button.
6. Deselect Compress contents to save disk space.
7. Deselect Encrypt contents to secure data.
8. Choose just this folder option.

Let us look at the steps in detail.

Run FSUTIL Command

Open Run prompt (Win +R), type cmd, and press Shift + Enter to launch the command prompt with admin permission. Type and execute the following command

fsutil behavior set disableencryption 1
fsutil behavior set disablecompression 1

Reboot the computer once done, and launch Ubuntu or any other Linux flavor.

Uncheck Compress Contents for Ubuntu directory

The Ubuntu directory is located at the following path

%localappdata%\Packages\CanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc

It is possible a Windows Update has enabled compression and encryption for that folder. If that is so, then you need to disable it

Go to %localappdata%\Packages\, right-click on the CanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc  folder, and select Properties.

Under the General tab, click on the Advanced button. Uncheck the box for compression and encryption. Click on and save the changes. The process may take some time, depending on the size of the folder and files.

When prompted to apply the changes to just the current folder or to all subfolders and files, select just this folder since you are only clearing the compress flag.

Following this, the change, wsl --set-version command should work and allow you to run a Linux environment, including most command-line tools, utilities, and applications.

Hereafter, your problem should be solved, and you should not see the WSL error 0xc03a001a again, says Microsoft.

Hope it helps!
