Windows 11 is an upgraded version of the previous iteration, but with a new design, apps, tools, and sounds. All the new features and the freshness is what attract people and this is why a lot of Windows users are in the process of clean installing or upgrading to Windows 11.
In case you’re still on an older Windows version, the easiest way to get access to Windows 11 is to sign up for the Windows Insider Program, downloading the latest version that Microsoft made public.
But while upgrading the Windows and remaining with all the files, it also transfers the corrupted files, junk, and performance problems.
Fortunately, you can avoid this issue altogether by doing a clean install of Windows 11, deleting everything on the driver you installed Windows 11 on. This will make your computer run as smoothly as possible.
Windows 11 Requirements
But before you do this, take the time to check the requirements of Windows 11 to make sure that your system meets them.
Note: In the past, Microsoft had a tool (PC Health Check) on their official site that compares the Windows 11 system requirements with your PC specs. But since that’s no longer supported officially, you can use an alternative like WhyNotWin11.
