Windows operating systems have a built-in tool inside Disk Management that lets anyone create, delete, or resize drive partitions. It's been around for a long time and usually works without any drama, but recently, some people have found that the Shrink Volume option is greyed out or unavailable in Disk Management. More than likely, it was introduced by a random Windows update, but it could be something else, so follow along as we guide you through some solutions.

  2. Best third-party tools to shrink a partition on Windows 11.

How to Fix Shrink Volume Is Greyed Out in Windows 11

The first thing you should check is the file system of the partition you want to shrink. Windows Disk Management works best with NTFS partitions. If the drive is formatted as FAT32, the Shrink Volume option doesn't usually work.

  • Open File Explorer.
  • Right-click the partition you want to shrink.
  • Select Properties.
  • Check the file system listed under the General tab.

If the drive uses FAT32, you need to convert it to NTFS. If you have stuff on the drive, you will want to make sure you have a backup first since this process will wipe everything.

  • Open File Explorer.
  • Right-click the drive and select Format.
  • Choose NTFS from the File System drop-down menu.
  • Select Quick Format.
  • Click Start.

After the formatting process finishes, open Disk Management again and you should be able to use the Shrink option without any issues.

Check If the Drive Is Encrypted

If the drive is encrypted, you won't be able to make any changes to it until it is unlocked. Normally, you can see if a drive is encrypted because it shows a little lock icon on it. But if you can't tell, the steps below will help.

  • Open Control Panel.
  • Go to System and Security.
  • Select BitLocker Drive Encryption.
  • Check the encryption status of the drive.

Defragment the Hard Drive

Windows 11 includes a built-in optimisation tool that can help rearrange files.

  • Press Windows + S and search for Defragment and Optimise Drives.
  • Open the tool.
  • Select the drive you want to shrink.
  • Click Optimise.
  • Wait for the process to complete.

Disable the Paging File

The Paging File might be locking things up, so disable it, then try to Shrink the Volume.

  • Press Windows + R to open the Run dialogue box.
  • Type sysdm.cpl and press Enter.
  • Open the Advanced tab.
  • Under Performance, click Settings.
  • Open the Advanced tab again.
  • Click Change under Virtual Memory.
  • Disable Automatically manage paging file size for all drives.
  • Select No paging file.
  • Click Set and then OK.
  • Restart your computer.

Disable System Protection

If the issue continues, temporarily disable System Protection. Keep in mind that disabling this feature removes existing restore points. To disable System Protection, use these steps.

  • Open System Properties.
  • Go to the System Protection tab.
  • Select your drive.
  • Click Configure.
  • Select Disable system protection.
  • Apply the changes.

After successfully shrinking the partition, enable System Protection again and create a new restore point.

Use a Third-Party Partition Manager

If Disk Management still does not allow you to shrink the volume, try using a third-party tool instead. There are tons and tons of them getting around that all work well. We generally use GParted, it works great with Linux too.
