I am using Insider Builds of Windows 10, and I have multiple Recovery Partitions that are taking up a large amount of space. Could someone tell me why this is and whether I need all of them, or if there is any way to tell which are important? Thank you!
Why there are multiple recovery partitions in Windows 10?
Every time when you upgrade your Windows to the next version, the upgrade programs will check the space on your system reserved partition or recovery partition. If there is not enough space, it will create a recovery partition. No wonder you have multiple partitions in Windows 10 with Insider Builds of Windows 10. If you do not want to Windows to create another recovery partition every time when you upgrade Windows, you can increase the size of system reserved partition or system recovery partition before upgrading your Windows.
Can I delete the extra recovery partitions?
When you upgrade to the new version of Windows, the previous Windows recovery partition will be nonfunctional, according to Microsoft. Therefore, you can delete these nonfunctional partitions to free up some disk space. The upgrade program creates new recovery partition by shrinking C drive. And as you may know that Windows can only shrink a partition from its right side, in this way you can tell which recovery partition is newly created.
For example, look at the screenshot below, you can tell the 500MB recovery partition is newly created. So, you can delete the other two nonfunctional recovery partitions. If you are still not sure to delete which partition, you can backup the recovery partition first and then delete it.
How to remove multiple recovery partitions in Windows 10?
Windows 10 Disk Management cannot be used to delete recovery partition if it has crucial files. You can use diskpart.exe and a third party software to delete the recovery partition.
Delete recovery partitions with diskpart
Step 1. Type "diskpart" in the search box, then in the best match results, right-click on "diskpart" and select "Run as administrator".
Step 2. At Diskpart prompt, type the following commands in order, each one should end up with the Enter key:
Type "list disk" to display all the disks. Please pay attention to the disk number that contains the recovery partition.
Type "select disk n", in which "n" should be replaced with the correct disk number.
Type "list volume" to list all the partitions on the selected disk. By viewing the partition label and partition information, you will know which one is the recovery partition to be deleted.
Type "select partition n" where n should be the partition number of the recovery partition.
Type "delete partition" to delete the recovery partition.
After deleting the recovery partitions, you can use the unallocated space to create new partition or extend other partitions. However, you still cannot extend the remaining partition with the new created unallocated space if the recovery partition appears before the C: drive.
