Enable or disable NTFS compression in Windows 10

4/1/2015

By default Windows 10 is configured to compress system files that are stored on NTFS volumes and that were not used in a long time. This is implemented to free up an additional disk space while retaining the ability to access the files. However, your computer may work slower while the compression is running, because it is a resource-intensive process.

If you don't want to allow Windows 10 to create a compressed files on all the NTFS volumes, you can disable NTFS compression using Group Policy Editor or command-line tool, or Registry Editor.

Log on to Windows 10 as an administrator to manage the NTFS compression settings.

Important: value that is set in Local Group Policy Editor has the highest priority. If Group Policy Editor is included into your edition of Windows 10, make sure the corresponding option in it is set to Not Configured before you start changing NTFS compression settings in any other way.

Using Local Group Policy Editor

1. Open Local Group Policy Editor.

2. Navigate to Computer Configuration > Administrative Templates > System > Filesystem > NTFS.

3. Double-click Do not allow compression on all NTFS volumes.
