Security :: BitLocker - Password Is Known But Unable To Decrypt
Jul 7, 2014
I have BitLocker enabled on a laptop's boot/OS drive. It has worked well for almost a year but it hung when shutting down the other day and I had to press and hold the power button for 4 seconds to power it off. Now when I power it back on, it asks for the password as normal but then it starts in recovery mode and asks for the recovery key as well. Unfortunately I do not have the recovery key.
I know that the password I am entering is correct because it rejects any other password (as would be expected) and only prompts for the recovery key when I enter the correct password.
Am I going to be able to recover my data without this recovery key it is asking for?

I have a Windows 8 Pro laptop with a single SSD. I just encrypted the entire drive using Bitlocker. The process prompted me to save the recovery key, which I did to an external drive. The encryption was successful but nowhere during the process was I prompted to choose a password. So I have the drive encrypted but when I reboot it does so normally without asking me for a key or password to access the drive.

I activated Bitlocker for my Operating system drive on a Windows 8 machine. But when starting the process I only can back up the recovery key. I have no dialog to choose how to unlock the drive. Thus even though Bitlocker is running, the PC can be turned and windows can be accessed by common user authentication. No password prompt appears at an early instant of the boot-process.

I recently upgraded my windows 8.1 to windows 8.1 pro as I wanted to enable bitlocker encryption on the laptop.
The issue is that I can't seem to enable or find bitlocker in any of the area's outlined. When I try to right click on the C: drive I don't have an option for bitlocker. When I go into control panel, there's no bitlocker icon. When I do a search on the machine for bitlocker I do get a "manage bitlocker" icon, but it's doesn't do anything when I click on it.
I have followed the tutorial on this site and downloaded/installed the reg files to enable it on a non tpm device. Can see that they did update the policy on the machine, but still no joy.
When I go into PC info on the machine in question I don't see anything about bitlocker. It's like it's not there. Do you have to add a windows feature to enable it?

We are facing an issue with bitlocker on Windows 8 machines since its not encrypting Hard disks through GPO. we are getting the below error on the log files
failed to initiate drive encryption with the following exit code: 80070057
We are using the same GPO for windows 7 machines and its working completely fine and also Bitlcoker_to_go is working fine with both OS's.
Is there anything specific in GPO to check for bitlocker encryption in windows 8?

I am "fresh" with BitLocker encryption. I need to encrpyt OS drive of laptop with Windows 8.1 and TPM chip. I have read few articles about encryption of OS drives with BitLocker ( with TPM / without TPM ) but never got a direct answer to my questions. So ... I want to ask:
1. Is it possible to encrypt the drive without using the TPM in case that there is TPM chip in the laptop because from what I have read BitLocker work with TPM by default but I don't want to use it. I have had already encrypt other laptops without TPM chips by setting up the group policies ( Computer Configuration Administrative Templates Windows Components Bit Locker Drive Encryption Operating System Drives and double click on Require additional authentication at startup ) and ... is it possible something like this to be made in this case ( when the laptop have TPM in it ).
What I want is the user to be asked for password on startup, recovery key to be saved to a file on external device( not to use usb flash drive as a key ) and to be possible simply to change my HDD in the future without need to manage TPM.
If this is not possible ... here is my second question:
2. Can I setup encryption with TPM like that:
- user to be asked for PASSWORD on startup
- recovery key to be saved to a file ( I don't want every time to use usb flash drive with recovery on it to unlock the drive ... what I want is just user to be asked for a password and when he enter the correct password the drive to be unlocked ).

I have a new Windows 8.1 machine and I wish to encrypt the drive using Bitlocker. It gives me 4 options to save a recovery key
1. Save to your Microsoft account
2. Save to a USB flash drive
3. Save to a file
4. Print the recovery key
Option 1 isn't available as I'm logged on using a local account.
i. What is the difference between options 2 & 3? i.e. I could save to a file on a USB drive
ii. Does option 2 mean the USB flash drive cannot then be used for other purposes?
iii. Does option 2 also mean I could use a USB external hard drive, or does it have to be a flash drive?
iv. Once the recovery key has been created, can the key then be copied to other locations or is it only going to work where Bitlocker puts the key?
v. Just thinking about printing the recovery key - can this be used without a password to access the drive, how sensitive/important is the printed key?

What should I do in order to enable BitLocker for not only C drive, but all of my partitions?

After I restored to default settings in the bios , I get into this problem of bitlocker requiring the key to start. I tried to suspend bit locker but bit locker management is not available . OS is win 8.1 , product is Dell Venue Pro 11 Tablet.
When I tried to use elevated command to disable bitlocker , the system does not recognize "protectors" in the command line.
What am I to do? I am sick of entering the very long Key , each time I bootup ...

I use Windows 8 PRO and BitLocker to encrypt my system drive. My notebook hasn't TPM module, so I changed group rules and allow to use BitLocker without TPM. I enabled BitLocker, write key backup to flash drive and use PIN to unlock BitLocker.
Everything works fine except one think... when I start computer, there is BitLocker start screen and I must write PIN.
Always, really ALWAYS first-time password is invalid. Tried to write it very, very slow and I'm sure its correct... but BitLocker said it isn't.
I must delete it and write again... click enter and... pass is valid! I try to use insert to show password - in this case, first-time password are correct and Bitlocker accepts its. Unfortunatelly, it isn't secure method.

My issue first originates with going through the windows 8.1 store app to upgrade windows 8 -> to windows 8.1.
"turn off bitlocker because it isn't supported in the edition of windows you want to install"
I am not sure whether i encrypted the drives after installing windows 8 or in windows 7, nevertheless i do know the encryption passwords to the drives. The biggest problem is therefore trying to remove/disable the encryption to upgrade.
The Applet in the control panel is missing for some reason. I have seen some guides which rely on this applet which is usually situated between auto play and colour management.
I would like to remove/disable the encryption for the upgrade, or confirm the idea that if i disconnect the two drives that are encrypted i could upgrade the OS to 8.1 and wouldn't need to worry about the encryption. The concern is that the 8.1 OS would not read the drives hence the upgrading message.
My specs are this , related to Bitlocker:
Windows 8 64bit - standard (non-enterprise, pro)Hard drives:1 X 128GB SSD - C:/ windows installed here ** NOT ENCRYPTED **1 X 2TB HDD - D:/ + E:/ **ENCRYPTED**1 X 3TB HDD - F:/ **ENCRYPTED**

I've recently encrypted my main drive, and all is well. However, I would like to be able to encrypt one of my data drives as well and bitlocker isn't even detecting the drive's existence under "Fixed Drives"
I'm on windows 8.1 machine, the encrypted main drive is a SSD drive, and the data drive is a regular WD spinning drive SATA drive. I would like to have the WD data drive encrypted as well...

I'm seeking full-disk encryption software. I want to encrypt the volume that my Windows installation is on.
First of all, does Bitlocker come on the home edition of Windows 8.1? I recall on previous versions it was only available in the Pro editions.
However, I would prefer to use an open-source disk encryption solution. I've searched but I have not found any that can encryption the Windows installation volume, the ones I found (such as TrueCrypt) can only set up additional encrypted partitions which is no good for me.

I have Windows 8.1 Core and Enterprise dual booted. Now, the real question here is, well I've read online that Windows 8.1 had finally added some of the encryption functionality of Bitlocker in a limited sense setup and turned on by default in all editions of Windows including Core - similar to how it does this with RT. The thing is on that point I've read about this, but no-one on the internet seems to know how to describe this functionality with more detail than just a mention of the existence of this.
Yes, I know Windows 8.1 is a brand new OS - so new that it won't be available to the normal public for another month and a half. And yes, I know, this RTM is still incomplete and when it will be complete within this next month and half maybe some of these new features (like the default limited Bitlocker as well as the Wifi hotspot functionality (which I figured out how to setup with Powershell, but there's no easy and normal way to go about doing this (how are normal people going to set it up? Normal people are afraid of Powershell/Command Prompt! Microsoft knows this - so I assume they'll address these concerns, and if they don't - there employees and executives must be smoking crack cocaine))).
But, what I'm getting at is this - is it safe for me to set up Bitlocker on the Enterprise edition/drive and let the Core edition/drive be as it is now? Is there a specific way I should go about doing this? If my concern on this is warranted - and it's a dangerous thing to try to do - which could have negative and unwanted consequences - than maybe I should just remove Enterprise, well if I should, then suggest that too. I like Bitlocker encryption for my more sensitive data - but I also like this Windows To Go feature as well. I would remove Enterprise if it's probably the best option. I am concerned of this too because I remember reading years ago that in reality having a dual boot setup of 2 editions of the same version of Windows (or just 2 editions of different versions) was/is actually something that isn't a good idea to have setup because it messes with the 2 versions of Windows somehow and drive C:, but I assume that as time has passed and technology has advanced maybe those issues that were authentic issues in the past might've been addressed with the new technology - but am unsure of this.
So, basically, the real question is - is dual booting these 2 editions of Windows safe in the new world of today with these new technologies - and if it is - is having the full Bitlocker functionality with Enterprise setup and having the Core OS setup as the main OS as well - safe?

I have a Microsoft Surface Pro 2 and I am running Windows 8.1 Pro Update 1.
I have been unsuccessful at building a WinPE image that provides BitLocker support. I searched around the internet and found many posts. Eventually, I ended up trying to build it with the various added packages I discovered in the various posts. However, in the end, none worked and this is the message I am getting after booting into my WinPE environment:
manage-bde.exe - Application Error
The instruction at 0xa20afa3b referenced memory at 0x0000013d.
The memory could not be read.
Click on OK to terminate the program
Here are the commands I eventually ended up using to build my WinPE image:
Code: dism /image:C:Bootmacriummount /add-package /packagepath:"C:Program Files (x86)Windows Kits8.1Assessment and Deployment KitWindows Preinstallation Environmentamd64WinPE_OCsWinPE-WMI.cab"dism /image:C:Bootmacriummount /add-package /packagepath:"C:Program Files (x86)Windows Kits8.1Assessment and Deployment KitWindows Preinstallation Environment
[Code] ....
But even with all that included, I still have the same error about the memory.
Will WinPE 5.0 x64 bootable environment work on a TPM-enabled machine? If so, how did you build your custom WinPE environment?

I turned on Bitlocker on three new Windows 8.1 laptops and saved the 48-digit recovery keys and associated identifiers, but I forgot to indicate which laptops they are associated with. Is there any way to find the identifiers/recovery keys on my laptops so I can document this? Or do I have to decrypt the laptop drives, turn off Bitlocker, and start all over again to generate new identifiers/recovery keys? My only options under Manage Bitlocker are Suspend protection, Back up your recovery key, and Turn off BitLocker.

So, the device uses an eMMC for the drive. Is it possible to set the ATA security password on the drive, just like you can for regular hard drives? I don't see an option in the BIOS to set it. Perhaps the option is there somewhere though.
I basically want to protect the data on the tablet. I don't think the BIOS administrator/user password provides sufficient security since that password can be reset and the data can then be accessed. I don't want to use software encryption since I don't want to slow the device down.

I am running Windows 8 and Outlook 2010. I have created a profile for my company's Exchange Server. The set-up is correct because my username is recognized. However when I try to access Outlook, I get asked for my credentials by "Windows Security." It has the dots in the dialogue box indicating that there is a saved password. Unfortunately, I have no idea what that old password is and where it is coming from. When I try to overwrite it with the new and correct password and check the remember my password box, it just ignores it and redisplays the security message with the old password pre-filled. I am dead in the water with my corporate email which I don't need to add is not good.
I have deleted anything that might be an Outlook credential using the Control Panel. I have deleted my profile and started from scratch. I have also deleted my personal MSN account email and tried that but with the same results. There are some that suggest that the password is stored in the registry, but I know from experience not to mess with the registry without some professional advice, especially with a new operating system.

Friend had Vista on a computer and bought Dell with Windows 8:
1- I am unable to remove password from sign-on. There appears to be no instruction as in Win 7/Vista.
2- Picture icons when transferred show only a general icon not an icon of the pictures as in Vista.
3- My friend accidentally removed the icon for the Instructions/ for Win 8 on the Start Menu. I cannot find the file for us to review.
4- When I try to Create a Password Reset disk, the program asks for a password reset disk disk and password to be installed?

As of late , after awaking from sleep mode, the Action Center is requesting me to re-enter my password. I am clueless as to why this is happening.
The only change is that I cancelled my MS Office 365 [P6] subscription.
Maybe the unlinking? of [original1@original1.onmicrosoft.com] from [original1@live.com] is causing this behavior. Dunno?
I had used the on microsoft as my Windows 8 login account and had a few problems with that.
So I deleted that 'user' and created a new one with the .live email.
But that was more than a year ago. It's not the end of the world or anything, just a bit annoying and worrisome that it may be a 'bogus' pop-up in Action Center.

My computer recently began requiring me to use password at startup. I had previously disabled.
I went to NETPLWIZ as suggested elsewhere (Log On User Account Automatically at Windows 8 Startup)
However, there is no box to uncheck that says "Users must enter username and password to use this computer." (see attachment)
What am I missing? I have also checked the Password Requirement on Wakeup in the Power settings and that shows "No" and the "Ctrl-Alt-Del" option is also not in place.

My computer died on me so I have jut got an Acer Aspire XC100 which I am pleased with though admit I'm struggling with Windows 8 so I am reverting back to desktop as much as possible.
When I get to Microsoft welcome/ log in page I use the password I created on registration and it's rejected time and time again until eventually it's accepted, this happens with my Windows Live password too.

There is a folder left over from an uninstalled product called "Symantec". When I attempt to delete this, I get the message "You require permission from SYSTEM to make changes to this file". Clicking the "Try Again" button does nothing and the same message reappears.
I have tried to take ownership of the file through Properties > Security > Advanced, however, I get this error:
"An error occured while applying security information to (file path). Failed to enumerate objects in the contianer. Access is denied."
I have also tried to use an elevated command prompt to run the takeown command on this directory, however, get the "Access is denied." message for all files.
how to delete this file - unlocker does not work either!
