I found a huge folder named Windows.old on my SSD, consuming a lot of storage. After running disk cleanup and deleting the previous version of Windows, the folder still remained unchanged or got smaller. Inside, I noticed some folders resembling the root of my C drive, but there were no installed programs—just what looked like driver installations. I really need about 10GB more space on my SSD, but I'm unsure if this folder is essential or not. I’m tempted to delete it, but I want to be careful and avoid damaging my Windows installation.
I just set up Windows 10 and went through a major update today. It handled that update as if it were a fresh OS install. Plus, I prefer not to rely on tools like CCleaner.
I attempted that, but it didn't eliminate it. The area was cleaned, though the folder still exists.
