Microsoft Access 2021 Professional – License Key for 1 PC

Microsoft Access 2021 Professional: a perpetual database license for Windows

Microsoft Access 2021 is the desktop database application from the Office 2021 family, sold here as a standalone product key for one Windows PC. It stores data in related tables, lets you interrogate that data with queries, and puts a usable front end on top with forms and reports. Small businesses run inventory, customer records, invoicing and job tracking on it. Departments inside larger companies use it as the tool that Excel grew out of, the point where a shared list becomes a real relational database with rules, relationships and history.

Our buyers usually know exactly what they want. They have an existing .accdb file that needs a licensed copy of Access to keep running, they need Access on a second workstation, or they bought an Office suite that does not include it. Office Home and Business and Home and Student never contain Access, and Microsoft sells it separately from those suites. If Access is the only app you are missing, and you would rather not pay for a full Professional Plus suite or a monthly plan, this key is the direct route.

Who buys Access 2021 today

Three groups keep Access busy in 2026. The first is the small business owner whose company runs on a database that a consultant built years ago. The forms work, the reports print, and replacing it with a web app would cost far more than a license key. The second is the analyst or operations manager who lives in Excel until a workbook reaches a hundred thousand rows and five people editing at once. Access gives that person relationships, validation rules and multi-user access with a short learning curve, because the datasheet view looks and behaves like a spreadsheet. The third is the developer or IT admin who uses Access as a front end to SQL Server, building forms and reports quickly while the heavy data sits on a server.

Access 2021 also matters for consistency. If your company standardized on Office 2021 Professional Plus, adding a matching Access 2021 to a workstation that only has Home and Business keeps every user on the same file format, the same VBA object library and the same ribbon. Mixed versions work, but matched versions avoid surprises when a colleague opens your database.

Key features of Access 2021

• Relational tables with data types including Large Number (bigint) and Date/Time Extended for higher precision and cleaner SQL Server compatibility
• Query designer for select, crosstab, update, append and delete queries, plus a SQL view for hand written statements
• Forms and reports with a visual designer, conditional formatting, subforms and grouped, totaled reports ready for print or PDF export
• Modern chart types, including bar, line, pie and combo charts, placed directly inside forms and reports
• Linked Table Manager for connecting to SQL Server, Azure SQL, SharePoint lists, Excel workbooks and text files through ODBC and native connectors
• VBA and macros for automating data entry, validation and business logic, with the object model developers have relied on for decades
• Split database design: tables sit in a shared folder, each user runs a front end copy, and a small team works from one dataset
• Refreshed Office 2021 look with dark gray and black themes, and the option to add new tables straight from the ribbon in Datasheet view

Access 2021 compared with other ways to get Access

Access ships in several forms, and the right one depends on how many other Office apps you need and whether you want a subscription. The table compares the standalone Access 2021 key on this page with its closest alternatives in our catalog.

Access has never had a Standard or Home edition. Every retail copy is the full product, so the Professional label on this key confirms that you receive the complete application with the query designer, VBA and the developer tools. The differences between versions come down to release year, support end date and how the key is activated.

System requirements

• Windows 10 or Windows 11 (Access 2021 is a Windows only application; there is no Mac version of Access)
• 1.6 GHz or faster dual-core processor; a 64-bit CPU is recommended
• 4 GB of RAM for the 64-bit version, 2 GB for the 32-bit version
• 4 GB of available disk space
• 1280 x 768 screen resolution or higher
• Internet access for the download and online activation; everyday use works offline
• Both 32-bit and 64-bit installers are provided; the 64-bit build lifts the memory ceiling for large recordsets, while the 32-bit build is sometimes required by older ActiveX controls

Windows 10 reached end of support on October 14, 2025, so we recommend installing on Windows 11 where possible. Access 2021 installs and activates on both. If the PC already has another Office 2021 app, choose the same bitness, because Windows does not allow 32-bit and 64-bit Office apps side by side.

How the license works

This is a perpetual license: a one-time purchase with no renewal and no subscription. One key activates Microsoft Access 2021 on one PC. Microsoft distributes Office 2021 apps as retail, OEM style and volume licenses, and the rules differ. A retail key can be removed from one PC and activated on another. An OEM style key stays with the computer it was first activated on. A volume (MAK) key draws from a fixed pool of activations and is intended for organizations. The license type for this listing is shown in the Product Overview table on this page, and our team will confirm it before you order if you ask.

Activation happens inside the application. Open Access, go to File, then Account, then Change Product Key, and enter the 25 characters from your email. If the PC has no internet connection, or Microsoft's servers request telephone activation, we walk you through the Installation ID and Confirmation ID exchange by email.

Support lifecycle, stated plainly

Access 2021 belongs to the Office LTSC 2021 release wave. Microsoft supports it with security updates until October 13, 2026. After that date the software continues to open, activate and run, but no further patches arrive. If you expect to use Access for many years on an internet connected machine, consider Access 2024, which is supported until October 9, 2029. If you need parity with an existing Office 2021 deployment, or you are keeping an older database application alive for a defined period, Access 2021 is the practical match, and it typically costs less.
