How to fix
Storport.sys GSOD
on Windows

So I’m trying to upgrade to build 15007, but right after rebooting the system, the screen is covered with a GSOD drive_irl_equal_or_less_equal on file storport.sys. I’m using Windows 10 Home on Lenovo H30-A8 (AMD A8 with R5 Radeon Graphics). I’ve noticed that many people are encountering this bug check, but there are practically zero fixes published yet. Would you be kind to comment on that? Many thanks in advance!

New Windows builds are released regularly in order to fix the bugs of predecessor builds as well as present new features and improvements. Recently, Windows 10 Preview build 15014 has been released, which is available for Windows 10 Insiders. Even though this build does not contain many new features and improvements, it’s a big step towards the release of the Creators Update,[ref en-1] which is scheduled this spring.

You must have already know that installing all available Windows updates is a must in order to maintain proper system’s performance, ensure its protection, and get the chance to access all new features. However, despite having lots of advantages, Windows 10[ref en-2] updates bring errors frequently and that’s the reason why people avoid installing them. Windows 10 Preview build 15014 is not an exception. People are massively posting questions on various IT discussion forums, including the official Microsoft forum, about storport.sys GSOD.[ref en-3]

Usually, the green screen of death prevents people from installing the build, but sometimes the build might be installed successfully, but once the system reboots, a PC user is greeted by a storport.sys error in a GSOD environment. This Windows 10 Preview build 15014 usually contain an error code driver_irql_not_less_or_equal, which is an extremely unpopular problem in all Windows 10 builds.

Earlier, the driver_irql_not_less_or_equal appeared in relation to mfewfpk.sys, ndis.sys, epfwwfp.sys, netio.sys, kbdclass.sys, and storahci.sys files. The latest build presented Windows 10 users with the driver_irql_not_less_or_equal (Storport.sys) GSOD. Even though the issue reminds the ones that we’ve just listed, the previous fixes do not apply for it.

Some people have reported that fixes like a clean boot, safe mode, or Windows Update Troubleshooter did not help and it seems that Microsoft does not have a proper solution yet. Therefore, if you have installed the build 15014 and encountered the GSOD, it's recommended to roll back to the previous build and wait until Microsoft fixes the bug.
