How to merge unallocated space in windows 10

Merging unallocated space in Windows 10 — whether using Windows tools or third-party programs — generally isn’t dangerous if you follow some basic precautions. But, like with anything that involves messing around with your drive partitions, there’s always a tiny bit of risk involved. 

Use reputable tools. If you’re going the third-party route, pick well-known, trusted software like A0MEI. They’re pretty reliable and have been around for a while. Don’t rush. Read each step, and make sure you’re doing what you intend to do. Moving partitions or resizing can go wrong if you click the wrong thing. Sometimes, the process takes a little while, and your PC might need to restart. Don’t try to do it during an important task or when your power is unstable.

About merging unallocated space in Windows 10, I’ve done this kind of thing without issues — just following good practices. But I’ve also heard stories from friends or seen online instances where, if something goes wrong, you might lose data or your drive could become unbootable. That’s why backups are your best friend here.
