What is the Office Customization Tool (OCT)?
The OCT is a free, web-based Microsoft utility for IT teams to preconfigure Office installations. It generates XML files to automate app selection, language packs, updates, and licensing for bulk deployments, replacing manual scripting.
Can I exclude apps like Teams or Access?
Yes. The OCT lets you toggle specific apps (Word, Excel, Teams, etc.) during configuration. For example, uncheck "Teams" to exclude it.
Can I use the OCT for single devices?
No. The OCT is designed for large-scale deployments (100+ devices). For individual setups, use the standard Office installer or alternatives like WPS Office.
How do I update Office after deployment?
Configure update channels (Monthly Enterprise, Semi-Annual) in the OCT. Updates are automatic unless disabled.
Are there alternatives to the OCT?
For simpler setups, consider WPS Office, which offers plug-and-play installations without complex configurations.
Conclusion
The Office Customization Tool (OCT) is the gold standard for IT teams managing large-scale Microsoft 365 deployments.
Its web-based simplicity cuts through the chaos of manual scripting, letting admins preconfigure apps, updates, and licenses in minutes, not hours.
While alternatives like PDQ Deploy offer broader third-party app support, OCT’s native integration with Microsoft’s ecosystem ensures seamless updates and compliance.
For smaller teams, tools like WPS Office provide plug-and-play ease, but lack OCT’s granular control over enterprise security or silent rollouts.
Why Choose OCT?
- Enterprise-First: Built for bulk deployments (100+ devices), not one-off setups.
- Cost-Free: Included with Microsoft volume licenses—no extra fees.
- Standardization: Enforce uniform settings, languages, and updates across teams.
OCT vs. Alternatives
- OCT vs. Manual XML: Less error-prone, faster, and no coding skills needed.
- OCT vs. Third-Party Tools: Tighter Microsoft integration, but fewer cross-platform features.
- OCT vs. WPS Office: OCT wins for compliance; WPS wins for simplicity.
If your organization prioritizes security, scale, and speed, the OCT is unmatched. For casual users? Stick to standard installers. But for enterprises, it’s not just a tool—it’s a deployment lifeline.
