Windows Calculator No Square Root

Windows Calculator is a versatile tool for basic arithmetic operations, but sometimes you may want to disable specific functions like the square root feature. This guide explains how to do that and why you might need to.

How to Disable the Square Root Function

Disabling the square root function in Windows Calculator isn't a built-in feature, but there are a few workarounds you can use:

Method 1: Using Group Policy Editor (Windows Pro/Enterprise)

Press Windows + R to open the Run dialog.
Type gpedit.msc and press Enter.
Navigate to: Computer Configuration → Administrative Templates → Windows Components → Windows Calculator.
Double-click on "Prevent access to advanced calculator functions".
Select "Enabled" and click OK.
Restart your computer for the changes to take effect.

Note: This method only works on Windows Pro and Enterprise editions. Home editions don't include the Group Policy Editor.

Method 2: Using Registry Editor (Advanced Users)

Press Windows + R, type regedit, and press Enter.
Navigate to: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced.
Right-click in the right pane and select New → DWORD (32-bit) Value.
Name the new value "DisableAdvancedCalculator" and set its value to 1.
Close Registry Editor and restart your computer.

Warning: Editing the registry can be risky. Make sure to back up your registry before making changes.

Method 3: Using a Third-Party Tool

If you're not comfortable with registry edits, you can use third-party tools like NirSoft's Calculator which allows you to customize which functions are available.
