Bitlocker Stuck on Encrypting [Causes & Solution]
BitLocker is a security feature in Windows that protects the data stored on your drive by encrypting it. When BitLocker encryption is enabled, Windows gradually converts the data on the drive into an encrypted format so unauthorized users cannot easily access it.
Usually, the encryption process runs in the background while you continue using your computer. However, sometimes you may notice that BitLocker is stuck on encrypting, the encryption percentage does not increase, or the process appears to remain at the same percentage for a long time.
This can be confusing, especially if you are using BitLocker for the first time. Fortunately, being stuck at a particular percentage does not always mean that BitLocker has failed. The process can slow down considerably when Windows is handling a large drive, there is heavy disk activity, the computer is running on battery power, or another system process is using the drive.
In this guide, we will explain the common causes of BitLocker getting stuck and show you how to troubleshoot the problem step by step.
BitLocker Stuck on Encrypting [Causes]
Before trying to fix the problem, it is useful to understand why BitLocker may appear to be stuck. In many cases, the encryption process is still working, but it is progressing very slowly.
One common reason is the size of the drive. Encrypting a large hard drive or SSD can take considerable time, particularly if the drive contains a lot of data. An older mechanical hard drive can take significantly longer than a modern SSD.
Another possible cause is heavy disk activity. If Windows is installing updates, downloading files, running antivirus scans, indexing files, or performing another disk-intensive operation, BitLocker may have fewer resources available for encryption.
A slow or unhealthy drive can also cause problems. If the drive has file-system errors or hardware issues, BitLocker may take an unusually long time to process the data.
The encryption process can also be affected when the computer loses power or repeatedly enters sleep mode. Although BitLocker is designed to handle interruptions, repeatedly interrupting encryption is not recommended.
Insufficient system resources may also contribute to slow encryption. Running many demanding applications while BitLocker is working can make the process appear frozen.
Finally, Windows configuration problems, BitLocker service issues, pending updates, or a problem with the encryption state can cause the encryption percentage to remain unchanged.
BitLocker Stuck on Encrypting [Solution]
If BitLocker is stuck on encrypting, first check its status using Command Prompt or Windows Terminal with administrator permission. Run manage-bde -status to see the current encryption percentage and protection state. If encryption is still progressing, leave the computer connected to power and avoid interrupting it. If the percentage remains unchanged for a long time, restart Windows, check the drive for errors, install pending Windows updates, and use BitLocker commands to resume or manage encryption.
Let’s explore the steps in detail!
Step 1: Check Whether BitLocker Is Actually Stuck
Before making any changes, determine whether BitLocker has genuinely stopped or is simply taking a long time.
If you recently started encryption on a large drive, give Windows some time to complete the process. The percentage may remain unchanged for a while and then increase again.
You should also avoid running demanding applications during this period. Close games, video editors, virtual machines, file-copying programs, and other applications that heavily use the drive.
If you are using a laptop, connect the power adapter. This prevents the computer from shutting down because of a low battery while encryption is running.
If the encryption percentage eventually changes, BitLocker is probably working normally and does not require a repair.
Step 2: Check BitLocker Status Using Command Prompt
Windows provides a command that lets you see the actual BitLocker encryption status.
Press the Windows key and type Command Prompt. When Command Prompt appears in the search results, select Run as administrator.
A User Account Control window may appear asking whether you want to allow the application to make changes. Select Yes.
Now type the following command and press Enter:
manage-bde -status
Windows will display information about the drive, including the Conversion Status, Percentage Encrypted, Encryption Method, and Protection Status.
Look specifically at Conversion Status and Percentage Encrypted.
If the percentage is increasing over time, BitLocker is still working. If it remains at exactly the same percentage for an unusually long period, continue with the following steps.
Step 3: Restart Your Computer
A simple restart can sometimes resolve temporary Windows or BitLocker problems.
Save your work and close your applications. Select Start, choose the Power option, and then select Restart.
Wait for Windows to restart completely.
After signing in, open Command Prompt as administrator again and run:
manage-bde -status
Check whether the encryption percentage has changed.
A restart can clear temporary system issues and allow BitLocker to continue processing normally.
Do not repeatedly restart the computer while encryption is actively progressing. One controlled restart is reasonable for troubleshooting, but repeatedly interrupting encryption is unnecessary.
Step 4: Check the Drive for Errors
File-system problems can sometimes interfere with encryption. Windows includes a tool called CHKDSK that can check the drive for file-system errors.
Open Command Prompt as administrator again.
Type the following command, replacing C: with the appropriate drive letter if you are encrypting a different drive:
chkdsk C: /scan
Press Enter and allow Windows to complete the scan.
The /scan option checks the drive for file-system problems without immediately performing an offline repair.
If Windows reports problems that require repair, follow its instructions before continuing with BitLocker troubleshooting.
If you are unsure which drive is being encrypted, use manage-bde -status first to identify the correct drive.
Step 5: Check BitLocker Encryption Again
After checking the drive, verify the BitLocker status again.
Open Command Prompt as administrator and enter:
manage-bde -status
Look at the Percentage Encrypted value.
If the percentage has increased, BitLocker has resumed normal progress. At this point, the best option may simply be to let encryption finish.
Keep the computer connected to power and avoid unnecessary disk-intensive activity until the process is complete.
Step 6: Resume BitLocker Encryption if Necessary
If encryption was paused or suspended, you may be able to resume it using the BitLocker command-line tool.
Open Command Prompt as administrator and enter:
manage-bde -resume C:
Replace C: with the drive letter that is being encrypted.
Press Enter and wait for Windows to process the command.
Afterward, check the status again with:
manage-bde -status
If Windows reports that encryption has resumed, allow the process to continue.
Do not use commands randomly if Windows reports an error. BitLocker commands can change the encryption state of a drive, so you should only use commands that match the current status.
Step 7: Install Pending Windows Updates
An outdated Windows installation can sometimes cause system-management features to behave unexpectedly.
Open Settings by pressing Windows + I.
In Windows 11, select Windows Update from the left side of the Settings window.
Select Check for updates and allow Windows to search for available updates.
If updates are available, install them and restart the computer when Windows asks you to do so.
After the restart, check BitLocker again using:
manage-bde -status
If encryption continues, allow it to complete.
Step 8: Reduce Disk Activity
If BitLocker is extremely slow, temporarily reduce the amount of work your computer is performing.
Close unnecessary applications and pause large file transfers. Avoid copying thousands of files between drives while encryption is running.
You should also avoid starting resource-intensive tasks such as gaming, video rendering, or large archive operations.
The goal is to give BitLocker enough access to the drive so it can continue encryption without competing heavily with other operations.
Step 9: Check for Drive Health Problems
If BitLocker repeatedly stops progressing, the storage device itself may need attention.
For an SSD or hard drive, check whether Windows reports storage problems. You can also use the manufacturer’s official storage-management utility to check the drive’s health when such a utility is available.
If the drive is showing signs of failure, such as frequent freezing, unusual noises from a mechanical hard drive, repeated file corruption, or Windows reporting storage errors, back up important data immediately.
Do not continue experimenting with encryption commands on a drive that may be failing until your important files are safely backed up.
Step 10: Check BitLocker Status After Troubleshooting
Once you have completed the troubleshooting steps, run:
manage-bde -status
again from an administrator Command Prompt.
Check whether the Percentage Encrypted value is changing.
If the value is increasing, leave the computer running and connected to power until encryption completes.
If the percentage remains completely unchanged for an extended period and Windows reports an error, note the exact error message. That information can help determine whether the problem is related to BitLocker, Windows, the file system, or the storage device.
FAQs
How long should BitLocker encryption take?
There is no single time that applies to every computer. Encryption time depends on the drive capacity, amount of data, drive speed, computer performance, and current disk activity. A large or slower drive can take several hours.
Can I use my computer while BitLocker is encrypting?
Yes, Windows generally allows you to continue using the computer while BitLocker works in the background. However, heavy disk activity can slow the encryption process considerably.
Should I turn off BitLocker if it is stuck?
You should not immediately turn off BitLocker simply because the percentage has not changed for a short period. First, check its status using manage-bde -status and determine whether encryption is actually progressing.
Does restarting the computer cancel BitLocker encryption?
A normal restart does not necessarily cancel BitLocker encryption. Windows is designed to maintain the encryption state, allowing the process to continue afterward. However, repeatedly interrupting an active encryption process is not recommended.
Why is BitLocker stuck at 0 percent?
BitLocker may remain at 0 percent temporarily while Windows prepares the drive and begins the encryption process. If it remains at 0 percent for an unusually long time, check the status with manage-bde -status and investigate possible drive or Windows issues.
Can a failing hard drive cause BitLocker to get stuck?
Yes. Drive errors or hardware problems can interfere with operations involving the storage device, including encryption. If you notice other symptoms such as file corruption or frequent freezing, back up your important files and investigate the drive’s health.
Summary
When BitLocker is stuck on encrypting, the first thing to remember is that a stationary percentage does not always mean the process has failed. Encryption can take a long time, especially on large or slower drives.
Start by checking the actual BitLocker status with manage-bde -status. Keep your computer connected to power, reduce heavy disk activity, and give Windows sufficient time to complete the operation.
If the process genuinely stops progressing, restart Windows, check the drive for file-system errors, install pending Windows updates, and use manage-bde -resume when the encryption state indicates that it can be resumed.
If BitLocker continues to remain stuck or Windows reports storage errors, pay particular attention to the health of the drive and protect your important files with a backup before performing more advanced troubleshooting.
