Apps Won’t Open on Windows? Here Are 6 Possible Fixes

When your apps don’t open, there’s something wrong with your settings or operating system. It’s rarely a specific program because most programs won’t prevent other apps from opening, even if they’re experiencing errors or hanging. It can be challenging to pinpoint the exact source of the problem, so general maintenance and troubleshooting are the best ways to get your apps to open again.

How to Fix Apps Won’t Open on Windows?

All you need to fix this problem is administrator access to the computer in question. Some of the solutions might work even if you don’t, though. However, you won’t have all the rights you need without administrator access.

Make Sure Other Screens Aren’t Detected

Since programs can open on a new screen, check to ensure your computer doesn’t think one is detected. It’s a quick way to change things up and ensure it isn’t a minor setting issue.

1. Press the Windows Key + P.
2. Choose PC Screen Only.
   
3. Attempt to open a program again.
4. If the program doesn’t appear, press the Windows Key + X.
5. Choose Task Manager.
   
6. Look through the list of programs to see whether the one you tried to launch appears in the list. If it does, you know it’s starting but not appearing.
   

If the program isn’t opening or even if it’s not appearing, restart your computer and try again. If it still won’t work, it’s time to start fixing things. 

Update Your PC

Updating your PC is an easy process, often put off because a restart is inconvenient. Now is the time to update Windows you’ve been waiting on.

1. Press the Windows Key + I.
2. Click Update and Security.
   
3. Choose Windows Update.
   
4. Click Check for Updates.
   
5. If updates are available, click Install Now and follow the prompts to install them.
   
6. Restart your computer. 

Once the computer is back on, try to run the apps that weren’t opening earlier. If they still won’t, you can proceed to update the Microsoft Store.

Updating the Microsoft Store

The Microsoft Store app needs to be updated just like your operating system. Updates roll out bug fixes and patch security flaws, which can help your system’s stability. While the new features they include are also an enticement, the important updates are largely invisible.

1. Press the Windows Key.
2. Type Microsoft Store and click the corresponding app.
   
3. Click the Library Option.
   
4. Choose Get Updates.
   
5. Let the updates finish downloading.
6. Follow the prompts to install the updates located.
7. Restart your computer.

When you’re done, check to see whether the apps will open again. If not, then a virus scan is warranted.

Perform a Virus Scan

Regular virus scans are a great maintenance tool to ensure the safety and functionality of your computer. Windows has built-in antivirus protection. If you use a different program instead, scan from the dashboard of that program.

1. Press the Windows Key + X.
2. Choose Settings.
3. Select Update and Security.
   
4. Choose Windows Security.
   
5. Click Virus and Threat Protection.
   
6. Click Scan Options.
   
7. Choose Full Scan.
   
8. Click Scan Now.
9. Follow the prompts to complete the scan and address any issues it found.
10. Restart your computer.

Full scans take longer than quick scans, but it is more thorough and the better option when you have unexplained system problems. 

Once you know no unwanted intruders are at fault for your program-opening issues, proceed to look for problems with the system.

Run Some Troubleshooting Scans

Troubleshooting scans seek out and, in some cases, repair computer problems. The four scans you should use are DISM, CHKDSK, the hardware and devices troubleshooter, and the System File Checker utility. Each may offer some insight into the problem.

1. Press the Windows Key + X.
2. Choose PowerShell (Admin).
   
3. Confirm that you want to run PowerShell as an administrator. It’s important to give it that access to your computer so it can successfully check all the system files.
4. Type dism /online /cleanup-image /restorehealth.
   
5. Press Enter.
6. Let the scan run.
7. Restart your computer and try to open a program. If it doesn’t work, proceed.
8. Open an Administrative PowerShell window.
    
9. Type sfc /scannow and then press Enter.
   
10. Wait for the scan to complete.
11. Restart your computer.
12. Open a new Administrative PowerShell Window.
    
13. Type msdt.exe -id devicediagnostic.
    
14. Press Enter.
15. Click Next on the Hardware and Devices Troubleshooter popup.
    
16. Follow the prompts to address the issues it finds. Depending on what it finds, there may be multiple issues with potential fixes. 
17. Restart your computer.

Check your hard disk for good measure if these scans don’t resolve any issues. Sometimes a damaged hard disk is the root of apps not opening properly.

1. Press the Windows Key + X.
2. Choose PowerShell (Admin).
   
3. Click Yes.
4. Type chkdsk X: /f /r /x. Make sure you replace X with the letter designating the hard drive with the operating system.
   
5. Press Enter.
6. Type Y to accept the scan running after the computer restarts.
   
7. Press Enter.
8. Restart the computer. CHKDSK will try to find problems with your hard drive and also attempt to repair them. If it can’t repair them correctly, you might need to get a new hard drive and reinstall Windows.

Once you’re done scanning your system, focus on the system resources to see if your computer’s processing power or memory is the problem.

Check Your Memory and CPU Usage

Your computer uses the CPU and RAM to process each command it’s given. If your system resources are occupied with other tasks, they may be unable to open the apps you request.

1. Press the Windows Key + X.
2. Choose Task Manager.
   
3. Click Performance. 
   
4. Try to open a program while watching the meters on the left side of the pane.
5. Check to see whether they shoot up when you attempt to open a program. If the CPU or Memory maxes out, you need to clear up some system resources to make space to open the program.
6. Choose the Processes tab.
   
7. Click CPU or Memory to order your programs and tasks by their usage.
8. Try to open a program.
9. Watch to see what’s using system resources. 

If it’s a particular program or process, kill it and try to open a different program. Your memory or CPU may be damaged if they’re showing consistently high usage without anything running. 

If programs still aren’t opening and you’re sure it’s not a hardware issue, restoring your system might be your best shot before a complete operating system reinstallation.

Roll Back and Restore Your Operating System

If you have a restore point save created before the problem started, you could go back to that and may regain access to your programs. A change you made might be the problem. However, it may rewind your computer to a point where you’ll miss programs and updates you’ve gotten since it was created.

If you roll back and still can’t open programs, reinstall Windows. 

What Do I Do If Only Some Programs Won’t Open?

If only some programs don’t open, it might be an issue with the programs or a file they have in common. Try repairing or reinstalling them. You can try to repair programs from the Apps and Features menu.

1. Press the Windows Key + X.
2. Choose Settings.
   
3. Click Apps and Features.
   
4. Find the app you want to try to repair.
5. Click Modify.
6. Click Repair, if the option is available.
   

This may fix the app without a complete reinstallation. However, if problems persist, doing a complete reset would probably work better. If a file is corrupt or damaged, a complete wipe of all files from that program and a clean installation will probably give you better results.
