Missing Partitions / Reinstallation Windows 10 Laptop

[LostHours]

I reinstalled windows recently, at least I think it was a successful reinstall of windows. It took a while to notice some partitions was missing. Everything's working as it should except for when I use FireFox, and then after a while, the system runs low on memory and everything just freezes.

I downloaded EaseUS and I can see the recovery partition, however, it isn't assigned a letter. Is there a way to recover or add it to the system? I really have no idea what I'm doing or what to do next.

I see the partitions in the disk management. How do I assign a drive letter to those partitions?

Thanks Jack. The whole issue/reason to do with re-installation was the fault of another person, so I'm kind of resistant to paying for a permanent solution. Is there a non premium solution to this?

Your main problem is the C partition of 913GB is almost full. The usable unallocated spaces are trivial in size.

If this is a very recent Windows OS install...someone really needs to redo it, and do it properly.
You have too many little tiny spaces that don't really do anything.


What exactly is taking up the space in your C partition?
Probably a bunch of System Restore points, Windows.old....and a whole bunch of other junk.

Who did this recent reinstall?

Sorry to say it was me who performed the recent installation. Should have reviewed a YT tutorial first. I did a whole lot of restore points in case editing registry went wrong. But most of it is just work stuff from an old HDD I was going to get rid off, but looks like I might have to keep it till its sorted.

Editing the Registry? What did you need to do in there?

1. I downloaded some registry hacks to remove onedrive from file explorer.
2. I created folders and changed values to remove or rather silence cortana.

You can disable OneDrive during the initial installation and setup.
