如果当您尝试使用新的功能更新更新 Windows 10 时(update Windows 10 with a new Feature Update)遇到错误代码 0x8007025D(error code 0x8007025D)以及伴随的错误消息Windows 无法安装所需文件(Windows cannot install required files)，那么这篇文章旨在帮助您。在这篇文章中，我们将确定此更新错误的可能原因，并提供您可以尝试帮助您缓解此问题的解决方案。
更新失败时，会收到如下错误信息提示：
Windows Setup
Windows cannot install required files. Make sure all files required for installation
are available, and restart the installation. Error code: 0x8007025D
经调查，错误代码 0x8007025D(error code 0x8007025D) = ERROR_BAD_COMPRESSION_BUFFER转换为指定缓冲区包含格式错误的数据。
USB 3.0 使用消息信号中断 (MSI)(Message Signaled Interrupt (MSI))模式与系统进行通信。而(Whereas)USB 2.0使用更老的中断请求 (IRQ)(Interrupt Request (IRQ))系统。USB 3.0 设备使用的新MSI系统的一项功能是异步处理设备和系统之间的数据传输。(MSI)这需要一个缓冲区，数据通过该缓冲区以高数据速率流式传输，然后由系统解码。如果您在功能更新过程中收到错误 0x8007025D，则可能是您的PNY设备正在向缓冲区发送错误或损坏的数据，您的设备的缓冲区被阻塞或您的设备无法正确解码数据。
(Corrupt)USB驱动器上的数据损坏意味着无法正确解码此数据，从而引发此错误。损坏(Corrupt)的数据可能来自用于创建可启动USB驱动器的损坏的ISO映像文件。(ISO)如果应该复制的文件丢失或损坏，您将收到此错误。该问题也可能是由于闪存驱动器损坏导致某个部分无法读取。如果您可能插入了另一个被读取为另一个磁盘驱动器的USB设备，这些设备发送到缓冲区的数据可能会导致错误。
此外，如果HDD或SSD有坏扇区或记录，并且Windows安装尝试将文件复制到此空间，则会将错误返回到缓冲区，进而显示错误 0x8007025D。坏的RAM也可能是导致此错误的原因。如果数据被复制到RAM的坏部分，则缓冲技术将收到错误，因此显示错误 0x8007025D。
为什么 Windows 无法安装所需的文件？
重新安装或更新操作系统时会出现该错误。如果您的安装介质损坏，可能会出现此问题。确保您的DVD光盘没有损坏。您可以在USB(USB)闪存驱动器上创建安装介质并重新安装Windows。
如何修复Windows中的错误代码 0x8007025D(Error Code 0x8007025D)？
首先要做的是运行Windows 更新疑难解答(Windows Update Troubleshooter)，看看是否能解决问题。对您的RAM进行故障排除。您也可以检查和更新您的BIOS。如果这不起作用，您可以在另一个闪存驱动器上创建可启动的Windows 10映像。(Windows 10)
Windows 无法安装所需文件，错误 0x8007025D(Error 0x8007025D)
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。
- 拔下任何外部设备
- 减小HDD或SSD磁盘空间的大小并对其进行格式化
- 下载(Download)新的Windows 10 ISO映像并在另一个 USB 上创建可启动驱动器
- 在您的RAM(RAM)上运行内存诊断并更换损坏的RAM棒（如果适用）。
让我们看一下与列出的每个解决方案相关的过程的描述。
1]拔下任何外部设备
此解决方案要求您拔下所有USB设备和其他外围设备，包括互联网电缆。大多数情况下，由于硬件驱动程序错误或驱动程序过时， Windows安装会抛出错误 0x8007025D。
事实证明，将文件复制到您的计算机后，Windows安装可能不再需要您的USB驱动器。只需(Just)拔下驱动器，看看安装是否会从停止的地方继续。
如果仍然遇到错误，请继续下一个解决方案。
2]减少(Reduce)HDD或SSD磁盘空间的大小并格式化
你只需要大约 20GB 的空间来安装Windows 10。因此，如果您在从 USB 驱动器安装新功能更新(installing the new feature update from USB drive)时遇到此错误，您可以尝试将安装分区减少到 125GB 左右。这将减少您要复制到的空间被损坏的机会。
在选择自定义安装(Custom Install)选项 Windows 10后，您可以通过单击扩展选项来减少磁盘空间。但是，(Extend)请(Make)确保您的硬盘驱动器健康并且没有以任何方式损坏。
如果您正在执行全新安装，请确保格式化要安装的分区。这将消除坏扇区和记录。选择自定义安装(Custom Install)选项后，您可以通过单击格式化(ormat)选项并接受格式化来格式化分区
之后(Afterward)，重试安装。如果问题仍然存在，您可以继续执行下一个解决方案。
3]下载(Download)新的Windows 10 ISO映像并在另一个 USB 上创建可启动驱动器
您下载的Windows 10 ISO映像可能包含无法解码或复制的损坏文件。USB驱动器或磁盘中完全有可能缺少该文件，特别是如果您通过图像创建下载了该文件。
此外，您的USB驱动器可能已损坏或有不可读的部分，然后缓冲技术将检测到此错误，您将收到0x8007025D – Windows 无法安装所需文件(0x8007025D – Windows cannot install required files )错误消息。
在此解决方案中，您需要下载新的 Windows 10 ISO 映像(download a fresh Windows 10 ISO image)，在另一个 USB 驱动器上创建可启动驱动器(create a bootable drive on another USB drive)，然后重试安装。如果安装仍然失败并出现错误，请继续下一个解决方案。
如果您之前使用的是USB 3.0，您可以尝试使用USB 2.0端口，因为它使用与USB 3.0不同的技术来读取数据。
4]在您的RAM上(RAM)运行(Run)内存诊断并更换坏的RAM棒（如果适用）
您可能会遇到此错误消息，因为如果Windows 10安装程序发现内存(RAM)损坏，则宁愿不在您的设备上安装Windows ，也不愿在安装后一直崩溃。
因此，如果您有两个RAM棒，每个至少 1GB，您可以尝试删除其中一个并尝试安装（如果第一个返回错误，请交换）。您还可以使用内置的内存诊断工具(Memory Diagnostics Tool)检查RAM错误。更换(Replace)任何损坏的RAM，然后重试安装。
Hopefully, one of these solutions will work for you!
Windows cannot install required files, Error Code 0x8007025D
If when you try to update Windows 10 with a new Feature Update you encounter the error code 0x8007025D with the accompanying error message Windows cannot install required files, then this post is intended to help you. In this post, we will identify the possible causes of this update error, as well as provide solutions that you can try to help you mitigate this issue.
When the update fails, you will receive the following error message prompt:
Windows Setup
Windows cannot install required files. Make sure all files required for installation
are available, and restart the installation. Error code: 0x8007025D
On investigation, the error code 0x8007025D = ERROR_BAD_COMPRESSION_BUFFER, which translates to the specified buffer contains ill-formed data.
USB 3.0 uses the Message Signaled Interrupt (MSI) mode for communications with the system. Whereas, USB 2.0 uses the much older Interrupt Request (IRQ) system. One feature of the new MSI system that USB 3.0 devices use is asynchronous handling of data transfer between the device and system. This requires a buffer through which data is streamed to at high data rates, which is then decoded by the system. If you receive error 0x8007025D during the feature update process, then it’s likely your PNY devices are sending bad or corrupted data to the buffers, your device’s buffers are choked or your device can’t decode the data properly.
Corrupt data on the USB drive means that this data cannot be decoded properly thus throwing this error. Corrupt data may be from the corrupt ISO image file used to create the bootable USB drive. If the file that should be copied is missing or corrupt, you will get this error. The issue might also arise from a bad flash drive that is corrupt of unreadable at a certain section. In the case where you might have plugged in another USB device that is read as another disk drive, the data sent to the buffer by these devices might cause the error.
Also, if the HDD or SSD has a bad sector or record and the Windows installation tries to copy files to this space, an error is returned to the buffer, which in turn displays error 0x8007025D. A bad RAM is also likely to be a cause of this error. If data is copied to a bad section of the RAM, then the buffering technology will receive an error, therefore, displaying error 0x8007025D.
Why Windows cannot install required files?
The error will occur when reinstalling or updating the operating system. This issue can occur if your installation media is damaged. Make sure that your DVD disc isn’t damaged. You may create an installation media on USB flash drive and install Windows again.
How to fix the Error Code 0x8007025D in Windows?
The first thing to do is to run the Windows Update Troubleshooter and see if that fixes the problem. Troubleshoot Your RAM. You may also check and update your BIOS. If that doesn’t work, you may create a bootable Windows 10 image on another flash drive.
Windows cannot install required files, Error 0x8007025D
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.
- Unplug any external devices
- Reduce the size of HDD or SSD disk space and format it
- Download a fresh Windows 10 ISO image and create a bootable drive on another USB
- Run a memory diagnostic on your RAM and replace a bad RAM stick (if applicable).
Let’s take a look at the description of the process involved in relation to each of the listed solutions.
1] Unplug any external devices
This solution requires you to unplug all your USB devices and other peripheral devices including the internet cable. Most of the time the Windows installation will throw the error 0x8007025D because of bad hardware drivers or outdated drivers.
It also turns out that after copying the files to your computer, Windows installation might not need your USB drive anymore. Just unplug your drive and see if the installation will continue from where it left off.
If still faced with error, continue with the next solution.
2] Reduce the size of HDD or SSD disk space and format it
You only need around 20GB of space to install Windows 10. So, if you encounter this error while installing the new feature update from USB drive, you can try reducing your installation partition to around 125GB. This will reduce the chances that the space you are copying to is corrupted.
You can reduce the disk space by clicking on the Extend option after choosing the Custom Install option Windows 10. Make sure, however, that your hard drive is healthy and not damaged in any way.
If you are performing a clean install, make sure that you format the partition you intend to install on. This will iron out the bad sectors and records. You can format the partition, by clicking on the Format option and accept to format, after choosing the Custom Install option
Afterward, retry the installation. If the issue persists, you can proceed with the next solution.
3] Download a fresh Windows 10 ISO image and create a bootable drive on another USB
There is a possibility that Windows 10 ISO image you downloaded has a corrupt file that would not be decoded or be copied. It is entirely possible that the file is missing from the USB drive or the disk especially if you downloaded the file via image creation.
Additionally, it’s possible that your USB drive is corrupt or has an unreadable section, then the buffering technology will detect this error and you’ll receive 0x8007025D – Windows cannot install required files error message.
In this solution, you will need to download a fresh Windows 10 ISO image, create a bootable drive on another USB drive and then retry the installation. If the installation still fails with the error, continue with the next solution.
If you were using USB 3.0 earlier, you could try using a USB 2.0 port since it uses a different technology from USB 3.0 to read the data.
4] Run a memory diagnostic on your RAM and replace bad RAM stick (if applicable)
You might be experiencing this error message because Windows 10 setup would rather not install Windows on your device if it finds a bad RAM than crashing all the time after installation.
So, if you have two RAM sticks, each of at least 1GB, you can try removing either and trying the installation (swap if the first one returns an error). You can also check for RAM errors using the inbuilt Memory Diagnostics Tool. Replace any bad RAM and then retry the installation.
Hopefully, one of these solutions will work for you!
