How to Resolve Steam Not Opening in Windows 10 PC

Steam is the most used and well-known PC gaming platform on the market. It has improved significantly since its release in 2003, but that doesn’t mean that the app itself is sometimes a little unstable.

When that happens, it’s understandably frustrating. If you’ve encountered the dreaded problem of the Steam client not opening, we’re here to help. Here are the most common causes and ways to fix them!

What causes the “Steam not opening” error on Windows 10 PC?

If you run Steam and nothing happens, maybe your connection is slow or unstable. On the other hand, it could be caused by corrupt installation files, an outdated software version, or a server crash.

RAM problems can occur that interfere with Steam’s performance, especially during the installation process. RAM problems can also cause problems when playing games.

Sometimes third-party antivirus programs interfere with Steam because online games use copyright protection features that trick antivirus programs into thinking they are malware. If you suspect that a third-party antivirus program is causing problems with your computer, first check to see if Windows Defender (Microsoft’s built-in antivirus program) is disabled.

How to resolve the error “Steam not opening” on Windows 10 PC?

Forcibly close all running Steam processes

We will first resort to the simpler techniques, and then move on to the longer and more technical ones. This solution is to use the “Task” process to kill all processes related to Steam and restart it.

Some processes don’t close completely when you close them, which causes Steam to open incorrectly. So when you try to restart them, they get to the point where your unclosed process is. The application will stop at this point, which should explain why your Steam won’t open.

  1. First, click on the search bar and search for “Command Prompt.”
  2. Now click “Run as administrator.”
  3. When the command prompt opens, type this command and press Enter :-.
    taskkill /f /IM “steam.exe”
  4. Wait for the command to execute, then try to run Steam again.

Launch Steam as an administrator

Sometimes, for no particular reason, you need to run an application with administrator privileges. You can run Steam as an administrator by right-clicking on the Steam client and selecting “Run as administrator”. This will give the client administrative privileges (i.e. both read and write), and if the problem occurred because of this, it will run as expected.

Setting the date and time

Steam not starting may be due to incorrect date and time on your system, as Steam collects data from your computer in real-time. If the time is not set correctly for your location, the initial handshake will fail and Steam will not open. In this case, adjusting the date and time on your system can solve the problem.

  1. In the system tray, right-click on the clock.
  2. On the list that appears, click “Adjust Date and Time.
  3. Disable and then re-enable the “Set time automatically” option.
  4. Now run Steam and see if it’s working properly.

Deleting the app cache folder

Steam uses the appcache folder to store various types of Steam configuration and application data. It saves the information to speed up the next time Steam starts up. However, a corrupted cache can prevent the Steam client from opening. In this case, deleting the Appcache folder may solve the problem. Note that this folder will be recreated the next time you start the Steam client.

  1. Open File Explorer and go to the following path: C: Program Files (x86)Steam.
  2. Save the appcache folder in a safe place by copying and pasting it.
  3. Right-click on the appcache folder and click “Delete” on the menu that appears.
  4. Now run Steam to see if it’s working properly.
  5. If it is, delete the backup folder you created in step 2.

Frequently Asked Questions

Click on it, then click on the "Uninstall" button. Click the power icon on the Start menu and restart your computer. If Steam still won't open, reinstall your antivirus program and move on to the next method. If Steam can be opened, try reinstalling a third-party antivirus program if it was corrupted by a Windows update.

There may be minor issues with programs or processes on your operating system that are preventing the Steam client from opening. Or perhaps the state or cache on your computer is preventing the client from working. You can try rebooting your computer to resolve these issues. Then check if you can open Steam.

  1. Go to your Steam library.
  2. Find the game you want to run.
  3. Right-click on the name of the game and select Properties.
  4. Switch to the Local Files tab.
  5. Click Browse Local Files.
  6. Find the executable file of the game, right-click it and select "Properties".

You may have done this on your Android device when apps were giving you trouble, but surprisingly, you can do it on Steam on Windows as well. The cache helps apps run faster, but sometimes it gets things wrong, which causes problems. Steam should start up without any problems.
