If your keyboard keeps typing capital letters even when Caps Lock is turned off, it can be extremely frustrating, especially when you’re working, chatting, or creating content. This issue is usually caused by stuck keys, accessibility settings, or driver problems—not a broken keyboard. Below is a complete, human-written, high-SEO guide explaining the most effective methods to fix this problem permanently on Windows laptops and PCs.
Method 1: Use Shift + F3 to Switch Uppercase to Lowercase and Start Typing
This is the fastest temporary fix, especially if text is already typed in capital letters.
Select the text that is typing in capital letters.
Press Shift + F3 once to change uppercase to lowercase.
Press Shift + F3 again if needed until the text becomes normal.
After this, start typing again and check if the keyboard types in lowercase normally.
If the issue continues, move to the next method.
Method 2: Check for Stuck Caps Lock or Shift Key and Restart Windows Explorer
Sometimes the Caps Lock or Shift key gets stuck virtually or physically.
Press the Caps Lock key 4–5 times slowly.
Press the Left Shift and Right Shift keys 4–5 times each.
Now restart Windows Explorer to reset keyboard behavior.
How to restart Windows Explorer:
Press Ctrl + Shift + Esc to open Task Manager.
Find Windows Explorer in the list.
Right-click on it and select Restart.
Wait a few seconds for the screen to refresh.
Test your keyboard again.
Method 3: Turn Off Sticky Keys, Filter Keys, and Toggle Keys
Accessibility features often cause unexpected capital typing.
Press Windows + I to open Settings.
Go to Accessibility.
Click Keyboard.
Turn OFF Sticky Keys.
Turn OFF Filter Keys.
Turn OFF Toggle Keys.
Close Settings and test your keyboard.
This step fixes the issue for most users.
Method 4: Change Caps Lock Behavior to Use Shift Key Instead
Windows allows you to control how Caps Lock is turned off.
Press Windows + I and open Settings.
Go to Time & Language → Typing.
Click Advanced keyboard settings.
Select Language bar options.
Open the Advanced Key Settings tab.
Click Change Key Sequence.
Select Press the SHIFT key instead of Press the CAPS LOCK key.
Click OK → Apply.
Restart your computer and check typing.
Method 5: Update Keyboard Driver (Most Important Fix)
Outdated or corrupted drivers often cause capital letter typing issues.

Expand Keyboards.
Right-click your keyboard and choose Update driver.
Click Search automatically for drivers and wait.
If that does not work:
Right-click the keyboard again → Update driver.
Click Browse my computer for drivers.
Click Let me pick from a list of available drivers.
Select the recommended or default keyboard driver.
Click Next and complete the update.
Most important step:
