As technology advances, the need for security in our devices also increases. Windows 10 Pro offers a feature called BitLocker, which can help protect your files from unauthorized access. However, not all devices have a Trusted Platform Module (TPM) chip that BitLocker requires to function. Don’t worry, though, as there is still a way to enable BitLocker on your device without a TPM.

In this post, we will guide you through the process of enabling BitLocker on your Windows 10 Pro device without a compatible TPM. We have also included a video tutorial that you can follow along with.

Step 0: Check if your device has a compatible TPM.

Before we get started, you should check if your device has a compatible TPM. To do this, press the Windows key + R on your keyboard to open the Run dialog box. Type tpm.msc and press Enter. If your device has a TPM, you will see a window that shows its status.

Step 1:

Follow the steps in the video to change the configuration of BitLocker so that it will allow you to set it up without a compatible TPM.

Step 2: Enable BitLocker

If your device does not have a compatible TPM, we can still enable BitLocker by using a password or USB key instead. To enable BitLocker, right-click on the drive you want to encrypt and select “Turn on BitLocker.”

Step 3: Choose your preferred unlock method

When prompted to choose an unlock method, select “Enter a password” or “Insert a USB flash drive.” If you select the USB option, you will need to insert the USB drive before proceeding.

Step 4: Choose how much of your drive to encrypt

You can choose to encrypt only the used space or the entire drive. Select your preferred option and click “Next.”

Step 5: Choose where to store your recovery key

Your recovery key is a backup that you can use to access your files if you forget your password or lose your USB key. Choose whether to save the recovery key to your Microsoft account, save it to a file, or print it. Make sure to store your recovery key somewhere safe.

Step 6: Begin the encryption process

Once you have chosen your settings and saved your recovery key, click “Start encrypting.” The encryption process may take some time, depending on the size of your drive.

Congratulations! You have successfully enabled BitLocker on your Windows 10 Pro device without a compatible TPM.

Please refer to the accompanying video for a visual guide and demonstration of the steps outlined in this post.

Increase BitLocker to 256-bit

Encryption is an essential security measure that helps protect your sensitive data from unauthorized access. One of the most popular encryption tools available for Windows 10 Pro is BitLocker, which can encrypt your entire hard drive or specific folders and files. By default, BitLocker uses 128-bit encryption, which is considered secure but not the most robust option. If you want to increase the encryption key to 256 bits, which is the highest level of encryption currently available, follow these steps:

In summary, increasing your BitLocker encryption key to 256 bits is an easy way to add more security to your data. With 256-bit encryption, you can rest assured that your sensitive data is well protected.

Remove Disabled Snaps.

 στο Bash / GNU/Linux  επισημασμένο με ετικέτα bash / clean up / free space / GNU/Linux / snap / ubuntu Από 
LANG=C snap list --all | awk '/disabled/{print $1" --revision "$3}' | xargs -rn3 sudo snap remove;

Let us break down the command for you:

  1. LANG=C sets the language to English (C locale), which can be helpful to ensure consistent behavior across different systems with different default languages. We used this to make sure that the word disabled will appear for disabled snaps and not some other translation.
  2. snap list --all lists all installed snaps (i.e., packages) along with their details. The output of this command is piped to the following command.
  3. awk '/disabled/{print $1" --revision "$3}' searches for lines in the output that contain the word “disabled” and prints the first field (i.e., the name of the snap) followed by the string “–revision” and the third field (i.e., the revision number). This output is piped to the next command.
  4. xargs -rn3 sudo snap remove takes groups of three arguments from the input and runs the command snap remove with those arguments. In this case, the first argument is the name of the disabled snap; the second argument is the string “–revision”, and the third argument is the revision number. This will remove all disabled snaps and their associated revisions.

So, in summary, the command searches for all disabled snaps on the system, extracts their name and revision number and then removes them using the snap remove command. This is a very useful command to free up some space without losing data or functionality.
