Introduction: A common small business risk
BitLocker is an important utility in small office/home office situations. For instance, your laptop is probably your office. The device holds emails, customer details, invoices, and passwords. If that laptop is lost or stolen, the impact on productivity can be serious.
BitLocker is used widely in disciplined business networks and Windows Pro/Windows Enterprise enable the feature by default. However, home users are exposed to the same daily risks that larger business plan for. So, why is this kind of security not enabled be default in Windows Home?
This is because Windows Home is designed for personal rather than business or professional use. Windows Home users are provided with a lite version of BitLocker called “device encryption” to simplify this kind of security. This article helps you understand why this choice is left to user discretion, even though Microsoft recommends BitLocker or device encryption in business or professional contexts regardless of your edition of Windows.

What is BitLocker?
BitLocker is built‑in disk encryption in Windows.
Encryption means your data is scrambled so it cannot be read without permission. If someone steals your computer and removes the hard drive, they still cannot read your files when the hard drive is secured this way.
With BitLocker and device encryption this protection happens automatically in the background. You do not need to open files differently or remember extra passwords in daily use for locally stored data. BitLocker or device encryption ensures:
- Protection of customer and client information
- Reduction of legal and GDPR exposure after a loss
- Protection for email, documents, and saved passwords
- Your data is encrypted in absolute terms
For a home office, BitLocker/device encryption is often the single most important security control you can enable.
Why BitLocker is not enabled in Windows Home by default
Windows Home is designed for personal use. Microsoft assumes:
- One main user *
- Personal files
- Lower compliance risk
- Minimal technical setup
* See our notes about Microsoft Windows accounts here.
Because of this, BitLocker is enabled by default for Windows “Pro” and “Enterprise” editions. These editions are aimed at people who:
- Handle business or client data
- Travel with laptops
- May face regulatory obligations
So, device encryption’s default “disabled” state in Windows Home is not a limitation of your hardware. It is a product positioning choice because Windows Home is not designed for professional users.
Does Windows Home use Encryption or BitLocker?
Although Windows Home does not provide the more fully configurable BitLocker available in Windows Pro and Enterprise, it still provides an option for BitLocker “lite”, which is managed by a utility called device encryption, which:
- Uses the same encryption engine as BitLocker
- Encrypts only the main system drive
- Turns on automatically on supported hardware
This can be configured in Settings -> Privacy security -> Device encryption

A common misunderstanding about BitLocker and ransomware
Users often worry that BitLocker could be used by criminals to lock them out of their resources, because of past and recent headlines about BitLocker ransomware.
It is true that ransomware can misuse many tools. However, this does not make BitLocker unsafe or unnecessary.
BitLocker protects data when a device is lost, stolen, or powered off. Ransomware is a different problem that requires backups and malware protection.
For small businesses and home professionals, the biggest real‑world risk is still device loss, not advanced cyber attacks. BitLocker and device encryption directly addresses that risk. For instance, if a spent computer is taken to a recycling centre, an encrytped hard drive cannot be accessed by third parties. For a spent computer that is destined for recycling, hard drives should be removed and physically compromised to prevent third parties recovering files and date from the hard drive.
What BitLocker does not replace
BitLocker is important, but it is not everything. You still need:
- good backups
- strong passwords
- up‑to‑date Windows security
- sensible email habits
- a data and file retention policy that is commensurate with purpose
Think of BitLocker as the lock on the office door, not the whole alarm system.
Summary: Is BitLocker worth it for a small business?
BitLocker is not about fear or complexity. It is about realism.
Small businesses are not immune to loss, theft, or mistakes. BitLocker/device encryption for small business and professional home users helps reduce the impact when something goes wrong. This is why it exists, and why Windows Pro includes the feature by default. Consider these eventualities if you lost your laptop today:
- would customer or professional data (including customer/client personal details) be safe?
- would emails be secure from third party access?
- could files be copied by third parties?
If not, device encryption for Windowns Home is worth serious consideration. Better still, upgrading from Windows Home to Windows Pro is often one of the lowest‑cost security improvements a professional users can make.
Remember, even though Microsoft does not force device encryption by default in Windows Home, Microsoft still recommends the utility.
