Each process is executed in its own instance of VM, which means totally isolated from your other applications. It is capable of running each Windows process in standalone safe virtualized environment (VM) and fully integrated to your desktop. If that doesn’t help, uninstall your 3rd party antivirus solution, restart Windows and try running Windows Backup again.Īvast anti-virus’s NG component (Secure Virtual Machines) may be the culprit in most cases.Īvast NG is a hardware based virtualization solution to provide more isolated test space. Intermediate/Advanced users can also perform a clean boot using Autoruns tool from Windows SysInternals. Later on, after completing the clean boot routine and clicking “Enable all”, you may uncheck those specific services (which you had disabled already) manually. Note: If you had disabled some services earlier, note down the names in a piece of paper.
Clean boot troubleshooting using the System Configuration Utility (msconfig)
#REDDIT EFI PARTITION SHOWING GOLDENKEY HOW TO#
Putting your system in clean boot state helps find if any third party applications or startup items are causing the issue. See how to perform a clean boot in Windows using the MSConfig utility.
#REDDIT EFI PARTITION SHOWING GOLDENKEY SOFTWARE#
To resolve the problem, disable the third-party security software temporarily and perform a clean boot. The issue may occur if EFI system partition is locked or another application is using files on the system partition. Third party security software protects the system files and may be causing this issue. The last backup did not complete successfully.įix: Windows Backup Failed To Get An Exclusive Lock on EFI System Partition
The advisory says it revokes bootmgrs.Check your backup.
#REDDIT EFI PARTITION SHOWING GOLDENKEY PATCH#
On August 9th, 2016, another patch came about, this one was given the designation MS16-100 and CVE-2016-3320.

So, if a system is running Windows 10 version 1607 or above, an attacker MUST replace bootmgr with an earlier one. Code that specifically checked the policy being loaded for an element that meant this was a supplemental policy, and erroring out if so. So, an attacker can just replace a later bootmgr with an earlier one.Īnother thing: I saw some additional code in the load-legacy-policy function in redstone 14381.rs1_release. Redstone's bootmgr has extra code to use the boot.stl in the UEFI variable to check policy revocation, but the bootmgrs of TH2 and earlier does NOT have such code. However, this is done AFTER a secure boot policy gets loaded. It's a file that gets cloned to a UEFI variable only boot services can touch, and only when the boot.stl signing time is later than the time this UEFI variable was set. It blacklists (in boot.stl), most (not all!) of the policies. I say "attempt" because it surely doesn't do anything useful. Now, what happens if you tell everyone to make a "secure golden key" system? Hopefully you can add 2+2.Īnyway, enough about that little rant, wanted to add that to a writeup ever since this stuff was found )Īnyway, MS's first patch attempt. And the golden keys got released from MS own stupidity. You seriously don't understand still? Microsoft implemented a "secure golden key" system. Also the irony in that MS themselves provided us several nice "golden keys" (as the FBI would say ) for us to use for that purpose :)Ībout the FBI: are you reading this? If you are, then this is a perfect real world example about why your idea of backdooring cryptosystems with a "secure golden key" is very bad! Smarter people than me have been telling this to you for so long, it seems you have your fingers in your ears. efi file must be signed, but it can be self-signed) You can see how this is very bad!! A backdoor, which MS put in to secure boot because they decided to not let the user turn it off in certain devices, allows for secure boot to be disabled everywhere! Specific Secure Boot policies, when provisioned, allow for testsigning to be enabled, on any BCD object, including element as well, which allows bootmgr to run what is effectively an unsigned. Text so you can avoid some annoying ass music:
