The Hidden Startup Directory
Microsoft Excel has a little-known legacy feature designed for power users: the `XLSTART` directory. Any workbook or template file placed inside this specific, deeply hidden system folder will automatically launch the moment you open the Excel application, before you even see the standard Start Screen. While this is useful for loading custom macros or a daily dashboard, it is often exploited by buggy add-ins or even macro viruses. If Excel is inexplicably opening a blank workbook named “Book1.xlsx,” a strange template file, or displaying a macro warning every single time you launch the program, there is almost certainly an orphaned file hiding in your `XLSTART` folder.
How to Locate and Empty the XLSTART Folder
The only way to stop these files from launching is to physically delete them from the startup directory using the Windows File Explorer. The challenge is that the folder is buried within hidden system directories.
1. First, you must configure Windows to show hidden files. Open File Explorer, click the View tab at the top, and ensure the checkbox for Hidden items is checked.
2. Navigate to your primary `XLSTART` folder. The exact path depends on your version of Office, but it is typically located here:
C:\Users\[YourUsername]\AppData\Roaming\Microsoft\Excel\XLSTART\
(Replace `[YourUsername]` with your actual Windows login name).
3. Once inside the `XLSTART` folder, look at the contents. Any file located here is what is causing your issue.
4. Delete every file inside this folder. Do not delete the folder itself, just its contents.
Checking the Secondary Startup Directory
If the primary folder was empty, or if the problem persists, Excel may be loading files from a secondary, program-level directory.
1. Navigate to the program files directory. For modern Office 365 or Office 2019 installations on a 64-bit machine, check:
C:\Program Files\Microsoft Office\root\Office16\XLSTART\
2. Again, delete any workbooks or templates found inside this folder.
The next time you launch Microsoft Excel, it will start up cleanly, showing only the standard Start Screen or a fresh, blank workbook, without automatically loading those annoying ghost files in the background.
