User case: Windows 11 slower than Windows 10 after upgrading

Anticipating a fresh system, an exciting new interface, and smooth operation, only to find that Windows 11 is remarkably slow? That must be frustrating. Windows 11 being slower than Windows 10 is not a rare case. Don’t worry; let’s explore the root causes and adopt targeted measures to avoid a recurrence of this situation.

Why Windows 11 is slower than Windows 10?

Windows 11 slower than Windows 10 may be attributed to several reasons. Some possible factors include increased system requirements, new features and visual effects, and potential compatibility issues with certain hardware or software. Besides, performance can be influenced by individual system configurations and the presence of background processes.

But, in most practical cases, the likely cause for Windows 11 slower than Windows 10 after upgrading can often be the shortage of storage space. As you may know, the minimum requirement for storage space when upgrading to Windows 11 is 64GB or more.

If you're using an older computer with only the minimum eligible space to upgrade from Windows 10 to Windows 11, it may not have enough room for the operating system to efficiently handle temporary files, updates, and system processes, thus finally leading to Windows 11 slower than Windows 10.

This limitation can also lead to bottlenecks, and slowdowns, and hinder the system's ability to store and retrieve data efficiently, placing additional strain on its resources. To solve this problem, you can use the following methods to expand storage space.
