How to change the Windows 11 language to Bulgarian

A new laptop from abroad or a clean install, and suddenly every Windows 11 menu is in English. In almost every case changing the language is free and takes a few minutes in Settings, with no reinstall; you only need a licence if your edition is Windows 11 Home Single Language, which allows just one language.

First step: check your edition

Open Start → Settings → System → About and look at the edition under Windows specifications. If it says Windows 11 Home or Windows 11 Pro, you can add as many languages as you need. If it says Windows 11 Home Single Language, read the section on that edition below first, because changing the display language is restricted there.

Step by step: Windows 11 in Bulgarian

The labels below are the English ones you will see before the switch.

1. Open Settings with Windows + I.
2. Select Time & language → Language & region.
3. Next to Preferred languages, select Add a language.
4. Type "Bulgarian", select it and choose Next.
5. In the Install language features window, keep Language pack ticked and turn on Set as my Windows display language.
6. Select Install and wait for the download. An internet connection is required.
7. When Windows says it needs to sign you out to apply the new display language, select Sign out and sign back in.

If Bulgarian is already installed but the interface is in another language, simply pick it from the Windows display language drop-down on the same screen, then sign out and back in.

Why some text stays in English

The display language applies to the user who changed it. The sign-in screen and newly created accounts may keep the old language until you copy the settings: in Language & region open Administrative language settings and use Copy settings to apply them to the welcome screen and new user accounts. Third-party programs have their own language choice and do not always follow Windows.

Region and regional format

Menu language and regional settings are separate things. On the same screen, under Region, there are two fields:

• Country or region – Windows and apps use it to give you local content, for example in the Microsoft Store.
• Regional format – controls how dates, times and numbers are written. With "Bulgarian (Bulgaria)" dates are shown as DD.MM.YYYY and the decimal separator is a comma.

The regional format matters especially in Excel: with an English format, numbers with a decimal comma and CSV files exported from Bulgarian systems may be read incorrectly. You can perfectly well combine an English interface with a Bulgarian regional format.

Garbled characters in older programs

If an older accounting or stock program shows question marks or meaningless symbols instead of Cyrillic, the cause is usually the language for non-Unicode programs. You change it in Administrative language settings with Change system locale, choosing "Bulgarian (Bulgaria)" and restarting the PC. This setting affects the whole system, so only change it if you actually have this problem.

Keyboard: BDS or phonetic

The display language and the keyboard layout are independent as well. Microsoft notes that changing the display language may also change the keyboard layout, so it is worth checking which layouts are installed: in Language & region select the three dots next to Bulgarian, choose Language options and under Keyboards use Add a keyboard.

Windows offers several Bulgarian layouts:

• Bulgarian (Typewriter) – the classic BDS layout known from typewriters. If you learnt to type "on BDS", this is most likely the one you want.
• Bulgarian – the newer standard layout, which differs from the classic one on some keys.
• Bulgarian (Phonetic Traditional) – the traditional phonetic layout, where letters sit on similar-sounding Latin keys (А on A, Б on B and so on). Most people who say they type "phonetically" use this one.
• Bulgarian (Phonetic) – a newer version of the phonetic layout with some letters in different places.

If a letter appears "in the wrong place", you have most likely picked the other of the two phonetic or the two BDS variants – try the neighbouring one. Remove layouts you do not need via the three dots next to them → Remove. Switch between installed keyboards with Windows + Space or from the language indicator on the taskbar.

Windows 11 Home Single Language: why you cannot add a language

Some laptops, especially those imported from certain markets, ship with Windows 11 Home Single Language. As the name suggests, it supports only one display language. When you try to add Bulgarian you will see a message such as "Only one language pack allowed" or "Your Windows license supports only one display language".

According to Microsoft, all other editions of Windows 11 support installing multiple languages, and to add languages on Single Language the system must be upgraded to Windows 11 Home or Windows 11 Pro. Settings cannot fix this – you need a product key for the other edition.

The most direct route is a Windows 11 Pro key: enter it under Settings → System → Activation → Change product key, the system upgrades without a reinstall and your files stay in place. After the restart, add Bulgarian using the steps above. Besides multiple languages, you also get the Pro features such as BitLocker and Remote Desktop.

The key arrives by email within 15 minutes during working hours, activation goes through Microsoft’s official servers, and if the key does not activate we replace it free of charge. We compare the editions in Windows 11 Pro or Home, and the detailed upgrade steps are in our guide to upgrading from Home to Pro.

The licence does not depend on the language

A common question before buying is whether you need a "Bulgarian" version of Windows. You do not: the product key activates the edition, and the language is added separately and free of charge in Settings, as described above. All Windows licences in our shop work with Bulgarian or any other language Windows supports. If you choose Windows 11 Pro, you can install the system in English and switch it to Bulgarian later, or the other way round – changing the language does not affect activation.

Microsoft Store and apps

Microsoft Store apps do not follow the display language directly but the Preferred languages list: they use the first language in it that they support. If you want Microsoft apps and websites in Bulgarian, drag Bulgarian to the top of the list. If an app has no Bulgarian translation, it falls back to the next language. Office has its own language settings: the language of Word, Excel and Outlook is changed separately, under File → Options → Language.

Common problems and fixes

• The language pack will not download. Check your internet connection and that Windows Update is working. On company PCs, installing languages may be restricted by the administrator.
• Nothing changes after installing. The display language only applies after you sign out and back in.
• The keyboard changed by itself. This is expected after a language change – add the layout you want again and remove the others.
• The sign-in screen stays in English. Copy the language settings to the welcome screen from Administrative language settings.
• There is no way to add a language. Check whether your edition is Single Language.

Summary

On Windows 11 Home and Pro the language is changed free of charge under Settings → Time & language → Language & region. If your edition is Single Language or you need a licence for a new PC, choose Windows 11 Pro – it works in Bulgarian and any other language Windows supports. The key arrives by email within 15 minutes during working hours 09:00–20:00, you receive an invoice, and if there is an activation problem the key is replaced free of charge. All options are in our Windows licences. If you have questions, we will answer in Bulgarian.
