Windows 10: Device Manager inaccessible. MMC.exe has been blocked "for your protection"

Already done a search, tried to do all the fixes that are suggested to recover from this. Nothing helps.


Why am I being blocked by my operating system from my own device manager? I cannot reinstall my NVidia video drivers. I cannot install Windows Store apps, I am guessing for the same reason as the error code seems to suggest I am not activated. My machine is activated. My account is listed as an Administrator. Why must you make this so hard? Give me access to my system back!

This is a Microsoft link on inaccessible boot device:

It is an intermediate level link.
There are more advanced steps that can be ran once the partition structure is known.
There are steps for repair of the boot sector, operating system, etc.
Sometimes this bugcheck can be caused by windows updates.

A reset save files equivalent may be able to be performed.
Alternatively a clean install can be performed once important files are backed up.

I'm not sure if this is helpful, but maybe you can have a try. Windows operating system backups a working registry for recovery purpose. You can perform registry backup restoring to fix the inaccessible boot device error. The pre-condition is that you can access to the Advanced startup opotions of your PC. You'll need to use the command prompt.
Also, steps are a little bit complicated. However, if you follow the guide strictly, no mistake should be made. You can Google how to restore from Registry Backup, or refer to this article for help. Inaccessible Boot Device Lenovo.

Micron Announces New 32GB E-MMC Devices

Continuing to deliver innovative storage solutions for mobile and consumer applications, Micron Technology, Inc. today announced their latest e-MMC embedded devices. At 32GB, they are the highest densities available on the market today and are fully compliant with MMC standards. In addition, these newest e-MMC devices from Micron take advantage of the company’s industry-leading 34nm MLC NAND process technology, and feature an extended temperature range (-40C to +85C) for automotive and industrial applications.






Micron’s new e-MMC product offerings will give consumers a significant increase in storage capacity for songs, pictures, and video, while also providing advanced NAND management features for application designers to simplify product designs and speed time-to-market. Customer samples are expected by the end of August with mass production expected in the second half of this year.

“e-MMC NAND devices are an effective solution for the needs of many consumer applications like cameras, cell phones, PDAs, and automotive infotainment systems. As an example, a 32GB e-MMC can hold 16,000 high-resolution digital photos, 8,000 songs, or up to 20 hours of high-definition video,” said Graham Robinson, Director of Segment Marketing for Micron’s memory group. Micron’s e-MMC products also greatly simplify system design by removing the requirements of the host memory controller to support NAND software drivers and complex NAND management techniques, including error correction code (ECC), wear leveling, and bad block management—replacing all of this complexity with a simple and ubiquitous MMC interface.

In addition to the impressive storage and feature options, Micron is providing e-MMC products qualified at extended temperatures, which makes them ideal for in-dash applications like navigation systems and other automotive applications that require a more robust operating range. Further, the JEDEC-standard interface minimizes the need for host software to accommodate process node migrations. “Ultimately, because Micron manufactures NAND, we are able to capitalize on our outstanding process technology, well-established IP, and a deep commitment to forwarding NAND memory to bring products like this to market. In fact, we also have the capability to pair e-MMC devices with low-power DRAM in Multi-Chip Packages (MCPs). Ultimately, our recent move to the 34nm process was a major accomplishment and these product lines directly benefit from that innovation,” said Robinson.

Micron’s e-MMC embedded memory offerings span from 1GB to 32GB devices and combine high-quality MLC NAND Flash memory with a high-speed MultiMediaCard (MMC) controller in a low-profile BGA package that measures a mere 14mm x 18mm x 1.4mm.
