I recently installed the Windows 10 Fall Creators Update. Now, each time I start my computer,  I'm prompted for the bitlocker recovery key. In response to each prompt,  I  enter the key hoping this will be the last time. But it isn't.  I've not noticed any other problems.  Once I'm logged in everything seems to run fine.  I have easy access to the key but it's a hassle to enter it every single time. I'm also not ready to rollback the update either... close but not there yet.  The computer is a two year-old Dell XPS 9550 with a single 500gb SSD running Windows 10 installed at the factory. It is regularly updated with  Windows patches and less frequently applied hardware patches.  Any ideas?

I'm using a laptop with TPM module with BitLocker-encrypted internal HDD, running Windows 7. Recently I've installed a Windows 8 on the external, eSATA drive. Windows 8 detected the Windows 7 and correctly replaced the bootloader with dual-boot option.  Unfortunately, I'm now forced to enter BitLocker Recovery Key each time I start the computer. The only workaround I've found was to disable TPM module in BIOS, and suspend BitLocker on the Windows 7 drive.  How to accomplish the following configuration:   Keep the BitLocker running on Windows 7 (internal drive)  Leave the Windows 8 (external, eSATA drive) completely unencrypted  Don't be bugged to enter Recovery Key each time during startup  No matter if the eSATA drive is plugged in, or not   Is it possible? I don't care if TPM is enabled and I just want the Windows 7 drive to be BitLocker-encrypted.

I have a .vhd image of a BitLocker encrypted drive.   When I mount and double click the drive, BitLocker wants me to enter a 48-digit recovery key and doesn't ask for a password.  Why is that so and how can I enter a password instead?    Note: I don't have either the key or the password of this drive. I'm trying to brute force the password using forensic software.

We've upgraded some machines to Windows 10 and realized there were some updates which updated as required. However, I realized there was no option available to stop the download similar to that on Windows 7 and 8.1. The only way I could stop the download was to stop the Windows Update service.  My question is does anyone know of a way to stop auto updates or is stopping the service is the only solution?

I don't normally use encrypted volumes on my Windows 10 Professional machine but needed to do so today.  I normally use the drive on another system that runs Windows 7 Enterprise.  I discovered this problem when I initially connected the drive and missed the Windows 10 toast notification to unlocked the drive.  On Windows 7 when you right-click on the drive, you get an option to "Unlock Drive..." which then displays a password prompt.  When I did this same action on my Windows 10 machine I got the following context menu:    When I attempted to Open the drive, I got the following error message:    This PC:    At this point, I disconnected the drive, connected the drive again, and unlocked the drive through the toast notification.  At this point, I want to know the reason I could not unlock the drive through Windows Explorer.  Why can I only unlock the drive through the toast notification?

my laptop has freezed, I restart it with power button but now, at start up, BitLocker said that:     You need to enter your recovery key because Secure Boot has been disabled. Either Secure Boot must be re-enabled, or BitLocker must be suspended for Windows to start normally.   I gone to UEFI settings and define a password to re-enabled Secure Boot but BitLocker when I restart comptuer said that Bios secure parameters has changed... It doesn't solve the problem.  The problem is I don't have my recovery key. I tried to recover my recovery key using Microsoft account but I had to update my phone number and so my security settings are locked for one month. My question is :   Is it possible to boot on Ubuntu USB key or plug HDD to an Ubuntu computer, copy files and decrypt them one by one with my password session ? Is it possible to retrieve my recovery key using Windows command line and session password ? (I can access to Windows recovery menu so I have access to commands line.) Is a program to decrypt completely my hard drive exists ? I will write it on a USB key, start it, enter my session password and it will decrypt all the disk or something like that.   Thanks a lot.

On my Lenovo Yoga 13 with Windows 8.1, quite frequently, when I want the computer to shutdown (by pressing on Shutdown explicitly), it reboots. (it has been like that for 2 weeks I think)  I have checked the registry key PowerdownAfterShutdown, and the current value is 0. I have read on other forums that it might help to change this value to for instance to 1, but, as I recently read on ,      Do not delete this entry from the registry or change its value. These changes can cause serious, unexpected results.   in the Caution section.  Is it that serious If I would change the value of the key, and would you recommend me doing so as a solution to this rebooting problem? Does anyone have a better solution to this problem.

I have a Dell laptop in which I have dual booted Ubuntu with Windows 10. Usually the laptop loads the Grub menu first.  Recently I had some problems with Windows Bitlocker: every time I open Windows I am prompted to enter the Bitlocker password. In trying to solve this, I accidentaly clicked Ubuntu in the "Delete Boot" option in the boot sequence. Now the laptop boots directly to Windows without first loading the Grub menu.  Luckily, when I restarted the system and clicked "add boot option" I found the efi folder in which the Ubuntu folder is present. In Ubuntu there is fwgrupx64.efi, grubx64.efi, grub.cfg, shimx64.efi, mmx64.efi, and BOOTX64.CSV. On clicking grubx64.efi it shows "Boot name not found".  How can I recover the Grub boot menu?

Recently as per this       For individuals who have chosen to receive automatic updates through   Windows Update, we help upgradable devices get ready for Windows 10 by   downloading the files they’ll need if they decide to upgrade.   but Microsoft seems to be downloading hidden update in windows 7 :  according to this  :     An INQUIRER reader pointed out to us that, despite not having   'reserved' a copy of Windows 10, he had found that the ~BT folder,   which has been the home of images of the new operating system since   before rollout began, had appeared on his system. He had no plans to   upgrade and had not put in a reservation request.   As per the above two articles there was hidden update for windows 10 with respective to windows 7 and 8 machines ,whats the effective way to stop this hidden update?  right now i cant disable windows update since i wish to patch my system with latest updates,  i checked the question which was marked as possible  :     inorder to clarify how it differs it talks about the cancelled update   ,but this was latest issue which was araised two days before,i didnt   dig much about that and believe both were different ,apart from that   it was about after the cancellation of update a   nd this one was about preventing such an update from downloading to my pc  any suggestions to avoid this update?

Installed Windows 7 Ultimate (64-bit) on a fresh PC and after installing service pack 1 started the upgrade to Windows 10. The assistant app downloads and verifies but gets stuck at 99% in the upgrading window phase. Even after hours it remains stuck there.  I've tried to reboot the machine and that doesn't help either. I've googled and found out that others have faced the exact problem but so far there isn't any solution that works.  Has anyone seen that situation and is there a fix for it?

This is a Q&amp;A that I recently have figured out, so I have posted the answer below.  After installing Windows 10, every time I get a kernel update or I run the update-grub2 it always shows Windows 7 or Windows Recovery Environment instead of Windows 10.  How do I fix this permanently?

I have not found any information from MS - only speculations from people like me, so I hope someone here has had better findings.  When I upgrade a qualified version of Windows to Windows 10 and then want to do a clean install, I've heard that the installer won't ask for a key. But what if my HDD is formatted before I attempt the clean install? How does Windows 10 try to detect the valid "upgraded" status? It seems that it doesn't in such a case, at least as far as I've tested.  So my question is: In that (or a similar) scenario: How do you clean install Windows 10?  In my case it's actually even more complicated. I'm from Germany so I can re-use OEM-licenses due to law. I have two qualified Windows OEM licenses which I both installed in a VM on my Linux installation and upgraded both to Windows 10.  Now I want to install one of them onto my bare physical machine - how would that be possible? Is there an official way of doing this or do I need to wait for those unofficial "backup license"-tools being updated to work with Windows 10?

Running Windows 7 Professional. It appears that the proper patch/update for me to protect against the wannacrypt virus is KB4012215.  I reviewed my Windows Update history and see that I tried to install that update on 3/18/17 but the installation "failed."  I right-clicked on it and the Error Code is 80070020.  Questions:   Is KB4012215 the proper update to guard against wannacrypt? If not, please tell me the proper update and where and how to download and install it. If so, please tell me where and how to download and install it.   Thank you.

So, I have Windows 7 pro, and I'm looking to upgrade so that I can use some of the apps that are only available in Windows 8+. I considered just taking advantage of the free Windows 10 upgrade, and actually installed it at one point, but then I found out that there's forced automatic updates and decided that wasn't for me(I'm a bit paranoid after Android 4.4.4 killed Flash Player without telling me. :P). So, I did some research.   From what I read, the Windows 10 upgrade "consumes" your Windows 7 license into a Windows 10 license, and so even if you revert back after upgrading then you can still change your mind later and jump back to Windows 10. () I also read that Windows 10 has "downgrade" rights to Windows 8 and Windows 7, which to my understanding meant that if you have a Windows 10 key, you can also use it to install Windows 8 or 7 if you want. ()  My plan for the process is re-upgrade to 10, pull the license key, downgrade to 8 and use the license key, then upgrade to 8.1 via Windows Store, and end up on 8.1. So my questions are: Is this possible?  Will it wipe all my data in the process?(not a dealbreaker if it does, but I'd need to know that so I can back it up) Do I need to re-upgrade to 10 in order to downgrade to 8?  Any input is definitely appreciated. Thanks!

I just did a fresh Window 10 installation from .iso files on the computer I was running Windows 7 on before. I have the original Windows 7 DVD's, with a valid key that I was using before.  Now I tried to enter the key of my Windows 7 DVD, but Windows 10 says it's not valid.  As far as I knew we were able to use those Win 7 keys on Win 10. What is wrong?

I am running Windows 10 with DiskCryptor whole disk encryption on the system drive.  The latest Windows 10 update fails to install.  When I restart the system to install the update, I get the following sequence of events:   I enter my DiskCryptor password which unlocks the disk Windows Update asks for the keyboard layout Windows Update then fails shortly after   If I push through the process far enough I get to a message that indicates it cannot continue because a file (or files) is locked.  My colleague also uses DiskCryptor on his system drive and has had an identical experience.  So:   Is this a known issue with whole disk encryption generally? Is this an issue with DiskCryptor specifically? If so, is it a bug MS will be fixing or will it require a workaround?

So I took a plunge and installed Windows 8 Consumer Preview on my main home PC. So far so good, but there is one annoyance - the system "locks" the computer after a period of inactivity causing me to re-enter my password.  I really would like to avoid this, but have no idea how. I already tried the power settings (no pass on wake up) and the screen saver settings with no luck. Is this some sort of bug, or am I missing something?  P.S. In this case I favor convenience over security.
