Toolbox can help you solve Office problems, but we cannot guarantee that these tools are 100% effective. In some severe cases, you may need to reinstall Windows to fix problems.

You can change the Office update channel and upgrade/downgrade without Office installation.
You can't change Office update channel for Office 2019/2021 Volume products.
# Check KMS status
By default, Office Tool Plus uses a TCP connection to test the KMS host, it cannot detect that the KMS host is working properly or not.
If Office Tool Plus detects a vlmcs component, it uses vlmcs for testing, including latency and activation results.
# Remove Office
Support for removing all versions of Office, including 2003 - 2021 and 365.
If something went wrong, you can try again later, or delete the files manually.
