Could you tell me where I am going wrong please? Your help would be really appreciated.

There seems to be something somewhere on the PC to do with the bitlocker that is stopping me at the last hurdle from resetting the PC.

I thought I had success when I went to control panel – administrative tools – services, because I was surprised to see a file called BitLocker Drive Encryption which I changed from manual to disable. Similarly if I right click on the drive (I only have 'c' drive) there is no bitlocker option. So if I type into the search bar near the start key 'bitlocker' or 'manage bitlocker', nothing appears for me to try to disable. This has meant that I haven't been successful in trying to locate where the bitlocker function is. This is the first time I have come across Bitlocker and I understand that Windows 10 Home does not have Bitlocker. You can enable Bitlocker after this process is complete. The problem is that when I try to reset the PC it gives me the following message: “Bitlocker must be disabled to proceed. I have Windows 10 Home version and really would like to restore the PC to factory settings.
