Intermittent keyboard shortcuts and unresponsive mouse dragging in Windows 11 often stem from driver conflicts, power management settings, or wireless interference. This guide provides a systematic approach to diagnosing and resolving these input device failures, ensuring reliable performance for both wired and wireless peripherals on modern systems.
Initial Diagnostic Steps
Before diving into complex software fixes, it is crucial to isolate the hardware from the operating system. Start by testing your keyboard and mouse on a different computer or USB port. If the issues persist across different machines, the hardware itself is likely defective. However, if the devices work perfectly elsewhere, the problem lies within your Windows 11 configuration.
Check for physical obstructions. For wireless mice, ensure the battery is charged and the sensor lens is clean. Dust or hair under the scroll wheel can cause dragging issues that mimic software glitches. For mechanical keyboards, try cleaning between the keys to rule out sticky switches causing shortcut failures.
Update and Reinstall Drivers
Outdated or corrupted drivers are the most common cause of erratic input behavior. Windows Update does not always fetch the latest manufacturer-specific drivers, which can lead to compatibility issues with advanced features like macro shortcuts or high-precision scrolling.
Navigate to Device Manager by right-clicking the Start button and selecting it from the context menu. Expand the "Keyboards" and "Mice and other pointing devices" sections. Right-click each listed device and select "Uninstall device." Do not check the box to attempt to remove the driver software unless you have manually downloaded the installer first; simply uninstalling allows Windows to reinstall the default driver upon restart.
After restarting your PC, Windows will automatically detect the hardware and install fresh drivers. Test the shortcuts and dragging functionality immediately. If the issue persists, visit the manufacturer’s website (such as Logitech, Razer, or Microsoft) to download the specific utility software. These tools often include firmware updates that fix known bugs related to polling rates and signal processing. For users experiencing similar hardware-specific quirks, reviewing

Adjust Power Management Settings
Windows 11 employs aggressive power-saving measures that can cut power to USB ports or wireless receivers during periods of low activity. This can cause the mouse to disconnect briefly or fail to respond to drag commands until it is moved vigorously.
Open the Control Panel and navigate to Hardware and Sound > Power Options. Click "Change plan settings" next to your active power plan, then select "Change advanced power settings." Scroll down to "USB settings" and expand "USB selective suspend setting." Change this setting to "Disabled" for both battery and plugged-in states. This prevents Windows from suspending the USB bus, ensuring a constant connection for your peripherals.
For wireless mice using a 2.4GHz dongle, consider using a USB extension cable to move the receiver away from the computer case. Metal cases and internal components can interfere with the radio signal, leading to packet loss that manifests as missed clicks or stuttered dragging. Placing the receiver closer to the mouse improves signal integrity significantly.
Check for Software Conflicts
Background applications can intercept keyboard shortcuts and mouse inputs before they reach the intended program. Macro utilities, screen recording software, or remote desktop tools often hook into input devices to perform their functions. If these hooks fail or conflict with system-level shortcuts, your inputs may become unreliable.
Review any recently installed software that interacts with input devices. Temporarily disable or uninstall such applications to see if the problem resolves. Additionally, check for overlays from gaming platforms like Steam or Discord, which can sometimes capture key presses unexpectedly.
If you are using a KVM switch or a sharing solution like Barrier to control multiple computers, ensure that the software is up to date. Interference from these tools can cause symptoms identical to hardware failure. For more information on managing shared input environments, see

Perform a Clean Boot
If the above steps do not resolve the issue, a third-party service or startup program may be interfering with input handling. A clean boot starts Windows with a minimal set of drivers and startup programs, helping to identify software conflicts.
Press Windows Key + R, type
msconfig, and press Enter. In the System Configuration window, go to the Services tab, check "Hide Microsoft services," and then click "Disable all." Next, go to the Startup tab and open Task Manager. Disable all startup items. Restart your computer.
Test your keyboard and mouse in this minimal environment. If they work correctly, one of the disabled services or startup programs is causing the conflict. Re-enable them in small groups to identify the culprit. This method is particularly effective for identifying malware or poorly coded background utilities that hijack input streams.
Frequently Asked Questions
Why do my keyboard shortcuts only work occasionally?
This is usually caused by a conflict with another application that has registered the same hotkey globally. Check your running programs for macro utilities or overlay apps that might be capturing the key press before Windows sees it.
Can a low battery cause mouse dragging issues?
Yes, insufficient power can lead to reduced polling rates or intermittent signal drops, making the cursor jump or fail to register drag events consistently. Replace the batteries or recharge the mouse to rule out power-related instability.
How do I stop Windows from turning off my USB ports?
Go to Power Options > Change plan settings > Change advanced power settings. Under USB settings, disable "USB selective suspend setting" to prevent Windows from cutting power to USB devices during idle periods.
Is it safe to uninstall keyboard drivers in Device Manager?
Yes, it is safe. Windows will automatically reinstall the generic HID-compliant driver upon reboot. This process clears out corrupted driver files and resets the device configuration without affecting your personal data.
What should I do if the mouse works but the keyboard does not?
Focus on the keyboard specifically. Check for stuck keys, clean the switch mechanisms, and ensure the wireless receiver is securely connected. If using a Bluetooth keyboard, forget the device in Bluetooth settings and re-pair it to refresh the connection profile.
