    For a super easy and safe way to partition a hard drive from Windows 10 without the stress, I'd totally recommend checking out a tool like Dr.Partition. It can resize and create partitions without touching your data, I've been using it for 2 years, highly recommended！

I just did this on my Win10 rig: I plugged in an external SSD and ran Control Panel → Backup and Restore (Windows 7) → Create a system image, plus synced docs to OneDrive—belt and suspenders.
Then hit Win+X → Disk Management, right-click C: → Shrink Volume, and on the new Unallocated space choose New Simple Volume (NTFS); it only touches free space, so your files stay intact.


Pro tips: temporarily suspend BitLocker, run chkdsk /f, free space/disable hibernation if shrink is tiny, and don’t convert to Dynamic Disk—you’ll be fine.
