What Is ospprearm.exe?
Ospprearm.exe (Office Software Protection Platform Rearm) is a legitimate executable file included with Microsoft Office 2016 (and other versions like 2013, 2019, and Office 365). Its official function is to reset the activation status of Office – specifically, to clear any cached activation data so that a user can re-enter a product key or reactivate Office after certain system changes.
When is it used legitimately?
- After cloning a hard drive or using a system image (to avoid activation errors on a new machine).
- When making significant hardware changes.
- During volume license deployments (with Key Management Service, KMS).
Important: The rearm process does not “crack” Office or provide free activation. It simply resets the grace period or clears activation data – you still need a valid license.
How to Use Ospprearm.exe to Reset Office 2016
If you are in a scenario where you need to rearm your Office installation (for example, your 30-day trial has expired and you need a few more days to activate it via KMS), follow these steps.
Core Function
Ospprearm.exe is a command-line utility that resets the activation grace period for volume-licensed versions of Office 2016. In non-subscription volume licensing (using a KMS host or MAK key), Office enters a 30-day initial grace period. After 30 days, if the product hasn’t activated with a KMS server, it enters a second 30-day "rearm" grace period.
Running Ospprearm.exe allows an administrator to:
- Reset the clock on the activation grace period.
- Return the license status to the initial licensing state.
- Gain additional time (typically 30 days) to fix KMS connectivity or network issues.
- Clear cached activation data before re-attempting activation.
Note: You cannot rearm indefinitely. Most Office 2016 VL editions allow a maximum of five (5) rearms. After that, a valid product key or KMS activation is mandatory.
Step 3: Run the ReArm Command
ospprearm.exe

Q2: Does Ospprearm.exe work with Office 2019 or Office 2021?
No. Those versions contain ospprearm.exe but in different paths (e.g., Office19 or Office16 still for compatibility). However, the rearm limit and behavior are similar.
