FEATURES
Features of Office LTSC 2021 for Windows
XLOOKUP lookup
Use the lookup function in Excel LTSC 2021. Find a record by code or name and return a related value from another range, such as a price or product category.
Word dark mode
Work with a dark document canvas. Adjust the working page's appearance for comfortable reading and editing without changing the document's color scheme.
ODF 1.3 format
Open and save files using the updated OpenDocument standard. This helps exchange files with applications that support OpenDocument. Check complex formatting separately after conversion.
A fixed set of features
Deploy a release without new app features being added later. A predictable toolset suits workplaces that need to maintain a consistent environment and previously tested workflows.
Excel dynamic arrays
Get a set of results from one formula: filter rows with FILTER, sort with SORT and return unique values with UNIQUE. The result size changes with the data.
Clearer formulas with LET
Assign names to intermediate results within an Excel formula. This makes complex calculations easier to read and lets you reuse parts without duplicating expressions.
Position lookup using XMATCH
Find an item's position in an Excel range with an exact or approximate match. Use the result in more complex data lookup and matching formulas.
Availability check
Check that your document, Excel workbook, or presentation is accessible to users of assistive technologies. Fix any issues found before sharing the materials.

Questions and answers
Is a direct installer available for Office LTSC 2021 for Windows?
No direct installer is currently available. — No verified direct English installer is currently listed for this option. Download is disabled; an account, store or installation-guide page is not used as a replacement file. Existing licenses and activation arrangements remain separate.
For Windows x64, should I download Office LTSC 2021 x86 or x64?
Both Standard options may be suitable for different reasons. — x86 is sometimes required for older add-ins; the Office architecture should match the other components on the PC.
How do I install Office LTSC 2021 for Windows in English?
Choose the language through the official installation or app settings. — In the Office Deployment Tool configuration, use the language ID en-us for English. Keep the product ID, update channel, architecture and license consistent with the official deployment guide.
Can I download LTSC 2021 on a work PC for free and activate it with a personal key?
A personal Office key is not an LTSC license. — Ask your administrator to check the organization's agreement and activation method before deployment.
What should I check before installing Office LTSC 2021 for Windows?
Back up your documents and confirm the release’s requirements and support status. — This release is no longer supported. Use it only where a licensed legacy workflow requires it, keep backups and plan a move to supported software.
