Start Excel in Safe Mode and Disable COM Add-ins

Running Excel in Safe Mode bypasses add-ins and customizations. If Excel runs smoothly in this mode, a conflicting COM add-in is likely causing the freezes.

Third-party COM add-ins are a common cause of performance issues in Microsoft Excel. By launching the application in Safe Mode, you can isolate whether an add-in is the root cause of the freezing on your new PC.

1
Open Excel in Safe Mode

Press the Windows key + R on your keyboard to open the Run dialog box. Type 'excel /safe' and press Enter to launch Microsoft Excel in Safe Mode.

2
Access Excel Options

Once Excel is open, click on 'File' in the top-left corner of the ribbon, then select 'Options' located at the bottom of the left sidebar.

3
Navigate to COM Add-ins

In the Excel Options window, click 'Add-ins' on the left panel. At the bottom of this window, change the 'Manage' dropdown menu to 'COM Add-ins' and click the 'Go' button.

4
Disable Conflicting Add-ins

Uncheck all the boxes in the list to disable the active add-ins, then click 'OK'. Close Excel and restart it normally to see if the unresponsiveness is resolved.

Start Excel in Safe Mode and Disable COM Add-ins
Isolating the Problematic Add-in: If Excel stops freezing after disabling all add-ins, re-enable them one by one, restarting Excel each time, to identify exactly which add-in is causing the issue.

Frequently Asked Questions

Why does Excel freeze only when I open specific workbooks?

Specific workbooks may cause Excel to freeze if they contain highly complex formulas, excessive conditional formatting, hidden objects, or corrupted data. Testing a brand new, blank workbook helps determine if the freezing issue is file-specific or caused by the application itself.

Will repairing Microsoft Office fix the freezing issue on my new PC?

Yes, running an Online Repair can fix corrupted Office installation files or missing registry keys that cause freezing. You can perform this by navigating to Windows Settings > Apps > Installed Apps, locating Microsoft 365, and selecting Modify > Online Repair.

How can I check my current Excel version if the program keeps crashing?

If normal mode crashes instantly, you can check your Excel version by opening the application in Safe Mode (type 'excel /safe' in the Windows Run dialog). Once open, navigate to File > Account, and your version and build number will be listed under the 'About Excel' section.
