Are your Excel macros running at a snail's pace rather than a sprint on your Windows 10 Pro machine? You're not alone. Many professionals encounter frustrating delays and slowdowns when running VBA macros in Microsoft Excel, especially on Windows 10 Pro systems. Whether you're managing data, automating reports or creating dashboards, macro delays can significantly impact productivity.
In this blog, we'll show you proven solutions to fix slow Excel macro performance on Windows 10 Pro. From system adjustments to Excel-specific optimizations, you'll find practical tips to get your macros running smoothly again.
Why do Excel macros run slowly under Windows 10 Pro?
Slow Excel macros can have several causes. Here are the most common ones:
- Inefficient VBA code or loops
- Add-ins or background apps that interfere with execution
- Low system resources (RAM/CPU)
- Outdated Excel or Office installation
- Problems with the configuration of Windows 10 Pro
Before you start with the solutions, make sure that your system offers the right environment. Consider upgrading to Windows 10 Professional + Office 2019 Professional Plus for optimum performance.
Step-by-step solutions for slow Excel macros
1. optimize your VBA code
Poorly written VBA code is often the main reason. Optimize by:
Deactivate ScreenUpdating:
Application.ScreenUpdating = False
- Deactivate automatic calculation:
Application.Calculation = xlCalculationManual
- Avoid Select and Activate:
Instead of:
Sheets(„Sheet1“).Select
Range(„A1“).Select
Selection.Value = „Test“
Use:
Sheets(„Sheet1“).Range(„A1“).Value = „Test“
2. deactivate unused add-ins
Excel add-ins, especially from third-party providers, can impair macro performance.
How to deactivate it:
- Go to File > Options > Add-Ins
- Click on Go to in addition to COM add-ins
- Deactivate unused add-ins
3. customize Excel and system settings
Make these changes for better macro speed:
- Start Excel in safe mode (Execute > excel /safe)
- Deactivate animations and visual effects:
- Control Panel > System > Advanced system settings > Performance settings
4. update Excel and Windows
Make sure that both are up to date:
- Office updates: File > Account > Update options
- Windows 10 updates: Settings > Update & Security
Use genuine licenses for best compatibility and stability. You will find trustworthy bundles like this Windows 10 Pro + Office 2019, which was developed for professionals.
5. check Task Manager for resource hogs
While macros are being executed:
- Press Ctrl + Shift + Esc
- Look for high CPU/RAM utilization
- Close unnecessary applications
Frequently asked questions about the slowness of Excel macros
Why are my Excel macros only slow under Windows 10?
Some older VBA scripts were developed for earlier versions of Windows and Excel. Compatibility or resource management in Windows 10 Pro may reveal inefficiencies, especially without proper system optimization.
Does the hardware influence the macro speed?
Yes, macros can be CPU-intensive. A computer with at least 8 GB RAM and a modern processor (i5 or higher) is recommended. In addition, the use of an SSD instead of an HDD can drastically reduce the execution time.
Is it better to upgrade to a newer Office version?
Yes, Excel 2019 and later offer improved performance, better memory management and smoother VBA execution. Consider a license package like this: Windows 10 Pro + Office 2019 Professional Plus (3 devices)
Best practices to avoid future macro problems
- Regular cleaning and refactoring of VBA code.
- Avoid volatile functions (NOW(), RAND() etc.).
- Use arrays instead of cell loops.
- Create backup copies of your Excel files.
- Monitor the file size and split large workbooks.
Further instructions can be found in the Microsoft documentation for Optimization of VBA performance and to best Excel practices.
Conclusion
Slow Excel macros on a Windows 10 Pro computer do not have to be a permanent problem. With code optimization, proper system configuration and up-to-date software, you can significantly improve macro performance. For long-term success, you should apply best practices and invest in optimized tools such as the Windows 10 Pro + Office 2019 Bundle to ensure seamless Excel automation.

FAQ
How can I determine which part of the macro is slow?
Use breakpoints or insert timestamps to identify delays:
Debug.Print Timer
Can antivirus software slow down Excel macros?
Yes, real-time scans can interfere with Excel's file operations. Add Excel to the exclusion list of your antivirus.
Is it safe to deactivate ScreenUpdating and automatic calculation?
Yes, as long as you reactivate it after the macro:
Application.ScreenUpdating = True
Application.Calculation = xlCalculationAutomatic
