Kaspersky Lab sells its anti-virus products at different prices in different regions and uses regionalized activation codes. A program bought in a country of a region can be activated in another country of the same region. Once activated, the software can also be used in and download updates from other regions as long as the license is valid. Problems may arise when the license must be renewed, or if the software must be reinstalled, in a region other than the one where it was bought. The region is identified by the IP address (there is no activation possible without Internet connection), so the use of VPN or a proxy is recommended to circumvent the restriction.
The only exception to this is the Chinese version of the Nintendo Switch distributed by Tencent in Mainland China. This version of the console can still play cartridge-based games from any region, however they can only connect to Chinese servers. Thus, it cannot access any game updates, DLC or online modes from games in other regions, or download said games digitally. Conversely, all other versions of the Nintendo Switch are unable to play cartridge-based games made by Tencent specifically for the Chinese Nintendo Switch.
All PlayStation 3 games except for Persona 4 Arena and Way of the Samurai 3, are region free. Although publishers could choose to region-lock specific games based on a mechanism that allows for the game to query the model of the PS3, none did so during the first three years after the PS3's launch. In the case of Persona 4 Arena; publisher Atlus declined to reverse its decision despite substantial outcry by some of their fanbase. The decision was made to avoid excessive importing, because all versions of the game share the same features and language support, but have differing price points and release dates in each region. They did, however, decide not to apply region-locking to its sequel (Persona 4 Arena Ultimax). There is region locking present for backwards-compatible PlayStation and PlayStation 2 games, as well as DVD and Blu-ray Disc movies. Additionally, some games separate online players per region, such as Metal Gear Solid 4: Guns of the Patriots. The PlayStation Store only contains content for its own country. For example, the EU store will not supply usable map packs for an imported US copy of Call of Duty 4: Modern Warfare. In addition, downloadable content for the PlayStation 3 systems is region-matched with the game itself. For example, DLC from the US PlayStation Store must be used in conjunction with a US-region game. More specifically, the PS3's file system includes region-of-origin, so DLC cannot be shared between different region games much like save files cannot. Also, the PSN Store is tied to each user's PSN account, and payment methods for PSN is also region-locked. For example, a user with a Japanese PSN account will only be able to access the Japanese PSN store despite owning a US PS3, and can only pay for a game with a Japanese PSN gift card or Japanese credit card. However, with a few rare exceptions, notably Joysound Dive, downloaded content from each PSN store are also region free, as are PSOne and PS2 classics offered on the store.
Starting with Windows Phone 7 for mobile devices and Windows 8 for computers, not all display languages are preinstalled/available for download on all devices with an OEM license of Windows. Users may not see all the display languages listed as options on the device or as options available for download as separate language packs. These exact options depend on the device manufacturer and country/region of purchase (and the mobile operator, if the device features cellular connectivity). Microsoft believes region locking is necessary because these display languages (which contains additional features like text suggestions, speech languages, and supplementary fonts) can take up a significant amount of storage, which leaves less space for data and media and impacts device performance. For cellular-connected devices, some mobile operators may choose not to support particular languages. For example, a wireless carrier in North America may not feel comfortable supporting European languages. 2b1af7f3a8
