How to Change Microsoft Store Country for HEVC Video Extensions
Question details
The user is unable to purchase the HEVC Video Extensions because the Microsoft Store checkout page locks the country/region, causing a payment failure.

- Product
- Microsoft Store
- Device & OS
- Windows
- Scenario
- Attempting to buy the HEVC Video Extensions from the Microsoft Store but blocked by an incorrect or unchangeable region setting during checkout.
- Observed behavior
- The country or region dropdown is grayed out or cannot be changed during the payment process, which prevents the user from completing the transaction.
Ensure you have a valid payment method that matches the billing address of the new country you intend to set, and note that existing account balances cannot be transferred between regions.
Update the Region via Windows Settings
Modify your system-level region preferences to match your physical location and payment method, which forces the Microsoft Store to update its regional storefront.
The Microsoft Store inherits its region settings directly from your Windows operating system. Therefore, you cannot change the region directly on the checkout screen; it must be updated in your main PC settings.
Click the Start menu and select the Settings gear icon, or press the Windows key + I on your keyboard.
Click on 'Time & Language' from the main settings menu, then select 'Region' from the left sidebar.
Under the 'Country or region' section, click the dropdown menu and select the country where you currently reside and where your payment method is registered.
Close the Microsoft Store app completely. Reopen it, search for the HEVC Video Extensions, and attempt the purchase again.

Frequently Asked Questions
Why can't I change the country directly in the Microsoft Store payment window?
The Microsoft Store locks the checkout region based on your Windows system settings to prevent users from bypassing regional pricing. To change it, you must adjust the system-level 'Time & Language' settings.
Will changing my Windows region affect my other Microsoft subscriptions?
Yes. Changing your region can impact the availability of region-specific content and the automatic renewal of subscriptions like Xbox Game Pass or Microsoft 365, as the store storefront changes entirely.
Do I need the HEVC Video Extensions to play videos in WPS Office?
WPS Office has robust built-in support for many common video formats in presentations. However, if you are working with heavily compressed HEVC (H.265) video files natively on your PC, having the OS-level extension installed ensures smooth playback across all applications.
What if the purchase still fails after changing the region?
If the payment still fails, double-check that your Microsoft account's online billing address matches the new Windows region. You can update this by logging into your Microsoft account on a web browser and navigating to 'Payment & billing'.
