Windows BSOD 0x000000D7 — DRIVER_UNMAPPING_INVALID_VIEW Fix

What Does This Error Mean?

Blue screen 0x000000D7 (DRIVER_UNMAPPING_INVALID_VIEW) means a driver tried to release a memory-mapped view that it did not originally create or that had already been released. This is a serious driver programming error — the driver attempted to free memory it does not own. Windows stops immediately to prevent memory corruption from spreading. This is almost always caused by a buggy third-party driver or a specific software conflict.

Affected Models

Windows 10
Windows 11
Windows 7
Windows Server 2016
Windows Server 2019

Common Causes

A device driver contains a bug where it attempts to unmap a virtual memory section it did not create
Two drivers are sharing a memory view and both attempt to release it, causing a double-free error
A driver is using an incorrect or stale memory address due to a race condition
Third-party virtualization or security software with a kernel component that mismanages memory views
RAM hardware instability causing memory address corruption in driver structures

How to Fix It

Run WhoCrashed (free from resplendence.com) to identify which driver caused the crash. Open the program, click Analyze, and read the crash report. Look for the driver filename listed under 'Probably caused by'.

This tells you exactly which driver to target without guessing.
Update or uninstall the identified driver. If it is a hardware driver, visit the manufacturer's website for the latest version. If it is from a security product or system utility, check for updates from that software's vendor.

If no update is available and the driver belongs to a non-essential program, uninstalling that software will stop the crashes.
Enable Driver Verifier to catch the exact moment the bad driver acts up. In Administrator Command Prompt, run: verifier /standard /all — then restart. Windows will now monitor all drivers closely and stop precisely when the bad one acts up.

Driver Verifier makes Windows more likely to crash on the bad driver rather than a random one. It narrows down the cause when WhoCrashed points to a generic driver.
Run Windows Memory Diagnostic to rule out bad RAM. Search 'Windows Memory Diagnostic' in the Start menu, open it, and choose to restart and check now. Review the results after Windows boots.

Faulty RAM can corrupt driver memory structures and cause this BSOD even when the driver code itself is correct.
If the crash began after a recent Windows update or software installation, use System Restore to go back to a point before the crash started. Search 'System Restore' in the Start menu and follow the prompts to choose a restore point.

System Restore does not affect personal files — only system settings and installed programs.

When to Call a Professional

This BSOD requires identifying the specific driver causing the fault, which can be done by analyzing the crash dump. If you are not comfortable with WinDbg or WhoCrashed, a technician can do this analysis and pinpoint the driver for you. Crash dumps are in C:\Windows\Minidump.

Frequently Asked Questions

What is a memory-mapped view?

A memory-mapped view is a technique drivers use to access a region of memory directly using a pointer. Instead of copying data back and forth, the driver maps the physical memory to an address in its own address space and reads or writes it directly. When the driver is done, it must unmap that view to free the address space. If a driver tries to unmap a view it never created, or unmaps it twice, Windows sees this as a critical error and stops.

Will Driver Verifier make my PC unstable?

Yes — intentionally. Driver Verifier puts all drivers under extra scrutiny and will BSOD the moment any driver breaks a rule. This makes the system crash more, not less, but it tells you exactly which driver is at fault. Only run Driver Verifier while troubleshooting, then disable it once you have identified the problem driver. To disable it, run: verifier /reset in Administrator Command Prompt and restart.

Could virtualization software like VMware or VirtualBox cause this?

Yes. Virtualization software installs multiple kernel drivers that handle memory mapping at a very low level. Bugs in these drivers or version mismatches with the installed Windows version can cause exactly this type of crash. If you have VMware, VirtualBox, Hyper-V, or WSL2 installed, try updating them to the latest version or temporarily uninstalling them to see if the crashes stop.
