Sửa lỗi NTFS compression is disabled please enable it trên WinToHDD

WinToHDD is one of the most widely used disk utilities that allows users to install, reinstall, or clone Windows 10/11 operating systems directly from internal drives without requiring USB boot drives or DVD installation media. However, when selecting target drive partitions or unpacking ISO/WIM image files, users frequently encounter a blocking error: "NTFS compression is disabled, please enable it".

Technical Root Cause: WinToHDD leverages native NTFS file compression APIs to extract, allocate, and write system packages to the destination volume. On stripped-down Windows Lite editions, custom ghost builds, or systems modified by aggressive registry cleaners, global NTFS file compression is frequently disabled. When WinToHDD queries the system flag and detects DisableCompression = 1, it halts installation to prevent disk corruption.

1. Overview of Troubleshooting Methods

Method Utility Used Estimated Time Effectiveness
Method 1: CMD Command (Recommended) Elevated Command Prompt using fsutil ~30 seconds Fastest, 100% accurate
Method 2: Registry Editor NtfsDisableCompression key in regedit ~1 minute Works across all Windows Home & Pro builds
Method 3: Group Policy Local policy management via gpedit.msc ~1 minute Clean GUI for Windows Pro & Enterprise editions
Method 4: Partition Properties Drive compression checkbox in File Explorer ~2 minutes Direct partition-level configuration

2. Detailed Step-by-Step Fixes

Method 1: Enable NTFS Compression via Command Prompt (Fastest)

  1. Press the Windows key, type cmd.
  2. Right-click Command Prompt > select Run as administrator.
  3. Copy and paste the following command into the terminal, then press Enter: fsutil behavior set disablecompression 0
  4. The console will confirm: "disablecompression = 0 (NTFS compression is enabled)".
  5. Restart your PC or re-launch WinToHDD to proceed with your Windows deployment.

Method 2: Enable via Windows Registry Editor

  1. Press Windows + R, type regedit, and hit Enter.
  2. Navigate to the following registry path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Policies (If the Policies subkey is absent, inspect: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem)
  3. Locate the DWORD entry named NtfsDisableCompression. If it does not exist, right-click the right pane > choose New > DWORD (32-bit) Value and name it NtfsDisableCompression.
  4. Double-click NtfsDisableCompression, change the Value data from 1 to 0 > click OK.
  5. Close Registry Editor and restart your computer.

Method 3: Configure via Local Group Policy Editor (Windows Pro / Edu)

  1. Press Windows + R, type gpedit.msc, and hit Enter.
  2. Navigate through the left tree: Computer Configuration > Administrative Templates > System > Filesystem > NTFS
  3. In the right pane, locate the policy: Do not allow compression on all NTFS volumes.
  4. Double-click the policy > set its radio button to Disabled or Not Configured.
  5. Click Apply > OK and restart Windows.

Method 4: Enable Drive-Level Compression in File Explorer

  1. Open File Explorer (Windows + E) > click This PC.
  2. Right-click the destination drive partition targeted for installation > select Properties.
  3. Under the General tab, check the box: Compress this drive to save disk space.
  4. Click Apply > choose to apply changes to the root folder > click OK.
Safety Notice: After completing your Windows installation via WinToHDD, there is no need to re-disable this feature. A value of 0 (enabled NTFS compression capability) is the default standard configuration shipped across all clean Microsoft Windows installations.

3. Frequently Asked Questions (FAQ)

Why does the fsutil command return "Access is denied"?

This occurs when Command Prompt is launched under standard user privileges. You must right-click CMD and select Run as administrator to modify low-level filesystem policies.

Does enabling NTFS compression slow down my computer?

No. Executing fsutil behavior set disablecompression 0 simply authorizes the operating system and installer utilities like WinToHDD to utilize compression algorithms when necessary. Your personal files and drives will not be compressed automatically unless explicitly requested.
