Fix Microsoft Project Freezing When Creating a Timeline
Question details
The user needs to resolve Microsoft Project becoming unresponsive when creating a timeline.
- Product
- Microsoft Project
- Device & OS
- Windows
- Scenario
- A user is creating a timeline in Microsoft Project on a Windows PC and needs the application to remain responsive.
- Observed behavior
- Microsoft Project becomes unresponsive or freezes during timeline creation.
Before troubleshooting, save your current project plan if Microsoft Project is still responding, and close other Office applications. Make sure you have permission to restart the computer, repair or uninstall software, and create a local Windows user account.
Perform a clean boot to identify conflicting software
Use this first because clean boot disables third-party startup programs and services, isolating the most common software conflicts without changing Project files.
A clean boot starts Windows with a minimal set of drivers and startup programs. If Microsoft Project works after a clean boot, a background program or service is likely causing the freeze.
Press Windows + R, type msconfig, and press Enter.
On the General tab, choose Selective startup and clear Load startup items.
Go to the Services tab, check Hide all Microsoft services, and click Disable all.
Open Task Manager, select the Startup tab, and disable each enabled startup item.
Restart the PC, open Microsoft Project, and create a timeline to see whether it still freezes.
Repair or reinstall Microsoft Project
Use this if clean boot does not stop the freeze, because a damaged installation or missing component can make Project unresponsive.
Test Microsoft Project with a new local Windows user profile
Use this when clean boot and repair do not resolve the freeze, because a corrupted user profile can also cause timeline creation to hang.
Use WPS Office as a free alternative while Microsoft Project is unavailable
WPS Office is a free, lightweight Office suite that opens Word, Excel, and PowerPoint formats with a familiar ribbon interface. It cannot open Microsoft Project .mpp files, but it helps you stay productive with project documentation, budget sheets, and timeline drafts while you repair Microsoft Project.

Frequently Asked Questions
What causes Microsoft Project to freeze when creating a timeline?
Common causes include background program conflicts, a damaged Microsoft Project installation, or a corrupted Windows user profile. Start with a clean boot to identify software conflicts.
How do I perform a clean boot for Microsoft Project troubleshooting?
Open System Configuration by typing msconfig in Start, choose Selective startup, clear Load startup items, disable non-Microsoft services, restart, and then test Microsoft Project.
How do I repair Microsoft Project instead of reinstalling?
Open Windows Settings > Apps > Installed apps, select Microsoft Project or your Microsoft 365 installation, choose Modify, and run Quick Repair or Online Repair.
