Understand the Device Limits for Office LTSC 2021
Office LTSC Professional Plus 2021 uses a device-based perpetual licensing model, limiting installation to a single device.
Microsoft Office LTSC (Long Term Servicing Channel) Professional Plus 2021 is designed as a traditional, one-time purchase. Unlike subscription models such as Microsoft 365, an LTSC license is tied to the hardware rather than a user account.
A single Office LTSC Professional Plus 2021 license grants you the right to install and activate the software on exactly one supported Windows PC or one supported Mac.
If you purchased through Microsoft Volume Licensing, you may have bought multiple licenses. However, each individual license unit from that pool still applies to only one endpoint device at a time.
If your computer breaks or is replaced, you are typically permitted to reassign the license to a new device. This reassignment is generally restricted to no more than once every 90 days, except in the case of hardware failure.
Try WPS Office for Flexible Multi-Device Access
If you are restricted by the single-device limit of an Office LTSC 2021 license, consider switching to WPS Office. WPS Office offers an easy-to-use, cloud-integrated suite that lets you work across multiple devices without strict hardware-bound limitations.
- 1. Download the Installer: Go to the official WPS Office website and download the installer tailored for your operating system.
- 2. Install the Software: Run the setup file and follow the straightforward prompts to install the lightweight suite.
- 3. Sign In for Cloud Sync: Create or log in to a WPS account to effortlessly sync your files and access them on all your devices.
Frequently Asked Questions
Can I install Office LTSC 2021 on both my laptop and my desktop?
No. A single Office LTSC Professional Plus 2021 license is valid for only one device at a time. You would need to purchase a second license to install it on a second computer.
Does Office LTSC 2021 receive new feature updates?
No. The Long Term Servicing Channel (LTSC) is a perpetual license that receives security and quality updates for a fixed lifecycle, but does not receive new feature updates after its initial release.
Can I transfer my Office LTSC license if I buy a new computer?
Yes, Microsoft usually allows you to reassign the license to a different device that you own, but this is typically restricted to once every 90 days to prevent abuse.
What is the main difference between Microsoft 365 and Office LTSC 2021?
Microsoft 365 is a subscription service that provides regular feature updates and allows installation on up to 5 devices per user. Office LTSC 2021 is a one-time purchase locked to a single device with no future feature updates.
