#2. Uninstall Apps

Aside from deleting or removing useless large files from computer hard drives, the other way that helps to free up disk space in Windows Server greatly is to remove corrupted or uninstall unwanted applications. Wise Windows experts know how to make full use of the disk space on Servers and they'll never allow big useless applications to take up such a big size. 

What to be removed? Here is a list: 

  • Huge & unnecessary applications
  • Useless games

How to Free Up Disk Space by Uninstalling Apps:

To do so, you can rely on the Programs and Features tool that helps you view the application size and remove unwanted programs successfully with the steps here below.

Step 1. Press Windows + X keys.

Step 2. Click "Programs and Features" from the result list to open this tool.

Open Programs and Feature

Step 3. Once the Programs and Features window opens, find and right-click on the programs or applications that you don't need in Server, click "Uninstall".

Uninstall apps

Repeat the steps above till you remove all useless apps on Server.

#3. Reset Virtual Memory Page File Size

The Page file is basically set for virtual RAM, and it takes up certain disk space in the system C drive. Mostly, when the Page Files gets too big, it would result in a 'high disk usage' issue in both Windows and Windows Server systems. 

To free up the disk space in Server, the best way is to reset the virtual memory page file size. Here are two options, and you may try either one based on your needs:

Option 1. Reset Virtual Memory:

Step 1. Press Windows + R keys, type sysdm.cpl ,3 and hit Enter.

Step 2. Click "Settings" under Performance at the Advanced tab.

Step 3. Go to the Advanced tab on the Performance page, click "Change" under the Virtual Memory section.

Step 4. Uncheck the "Automatically manage paging file size for all drives" box.

Step 5. Select Windows drive like C, and enter the recommended size as its Initial size for the virtual memory.

Change and reset virtual memory

Option 2. Move Page File from C Drive to Another Drive:

Step 1. Press Windows + R keys, type sysdm.cpl ,3 and hit Enter.

Step 2. Click "Settings" under Performance at the Advanced tab.

Step 3. Go to the Advanced tab on the Performance page, click "Change" under the Virtual Memory section.

Step 4. Uncheck "Automatically manage paging file", then click C drive and select "No paging file". 

Step 5. Click "Set" to disable the page file on C drive.

Reset virtual memory

Step 6. Select a target drive to transfer page file, click "System managed size", click "OK".

Move Page file to another drive

After this, you need to restart the computer to keep all changes so as to make the operation effective.

Notice: Some Server computer hard drive partition has small storage capacity, but there's still some unallocated space or free space on the disk. And if your Server is with this case, you are good to go and try Method 4 and Method 5 as introduced below.

#4. Add More Space, or Upgrade Disk to a Larger One

When your hard drive still has unallocated space that hasn't been used, you can add unallocated space to extend the hard drive partition. Or, if you tend to upgrade the disk to a larger one, you can clone the drive to a bigger HDD/SSD with reliable Server disk cloning software.

To do so, Windows Server administrators would prefer reliable Server partition manager software for help. Experienced Server users know how to pick such a tool, and EaseUS Partition Master Enterprise is one of the favored partition managers for Server users.
