What is WinDemo.Wim and How to Remove it

The Windows Imaging Format (WIM) is a file-based disk image format. It was developed by Microsoft to help deploy Windows Vista and subsequent versions of Windows operating system family, as well as Windows Fundamentals for Legacy PCs.

At retail stores devices on display are known as retail demo devices. Retail demo devices and content installed on them are responsible for the customer experience at the stores because customers often spend a considerable chunk of their time playing around with these devices.

WinDemo.wmi is a windows image file used to restore the demo image on the system. Users usually would delete the file to reclaim the hard drive space used by the recovery image.

Solution:

The recovery images are usually stored in a hidden recover partition. We’ll discuss about accessing the partition and deleting it but you should make sure you have the recovery media for your system or create it using the Recovery media creation tools provided by the manufacturer in case you need to restore your system in the future. Follow the steps below to:

  1. Hold the Windows Key and Press R to open run dialog and type diskpark in it and click OK.
  2. At the Diskpart prompt, type list disk to display all the disks. All disks on your computer will be listed with a disk number
  3. Select the disk that contains the recovery partition by typing select disk n, in which “n” should be replaced with the disk number listed before
  4. Type list volume to list all the partitions on the selected disk with all the partition labels, so you can determine which one is the recovery partition to be deleted
  5. Specify the partition you want to delete using the volume number, like this: select volume 3
  6. Type delete partition and hit Enter
  7. Hold down the Windows key + R to bring up the Run dialogue
  8. Type diskmgmt.msc and hit Enter
  9. This will bring up the Disk Management windows which will display all drives on the system and the partition.
  10. The deleted recovery partition would show up as unallocated space. To reclaim the space you can either create a new volume or add the space to the existing partition.
  11. Right click on the unallocated space and choose Create new volume to create a new partition
  12. To add the space to an existing partition Right click on the existing partition and select Extend Volume
