Hyper-V existing Virtual HDD

Hello,

I have got in to little trouble our VM host was corrupted because of sudden power loss so i had to rebuild VM-host machine and then created new VM using hyper-v manager by attaching existing HDD, i thought i should have current user data on it but strangely it has previous user who was using this vm a month ago data on it but no data for current user who used it even last week, I still have VHDX  files from few days back in C:\Users\Public\Documents\Hyper-V\Virtual hard disks, so i was wondering is there any way if i can apply vhdx file to existing VHDD or any other way to get current user data back i have attached the picture of hyper-v HDD's
Thanks

If you have a checkpoint created you need to manually merge the checkpoint file into the main VHD. This is a good technet article that walks you through the process. Once the checkpoint has been merged back you should be able to see all the changes from the new user.

This is one reason why I generally try to avoid keeping checkpoints on the system longer than absolutely necessary, it tends to overcomplicate these kinds of issues. The other good option is to use an imaged based backup of the VM itself which should ignore the checkpoints and just back up the whole machine.

Did you have checkpoints created on this VM between a month ago and now? I've found that if you simply remount the VHD file it doesn't include any data that was written to the checkpoints.

I had a check point created right after switch over new user to this VM and when i mounted the HDD to new VM there weren't any checkpoint shown in hyper-v manager, but i still have VHDX files from previous dates if look at the attached picture
