How to Fix CMD Prompt Issues After Windows In-Place Upgrade

Learn how to troubleshoot and resolve the common issues that may occur when you open a command prompt after upgrading your Windows server.

Problem

If you have recently performed an in-place upgrade of your Windows server from an older version to a newer one, you may encounter some problems when you try to use the command prompt. For example, you may notice that the command prompt does not open in the default directory, or that you cannot run any programs in the system32 folder. In this article, we will explain why these issues happen and how to fix them with some simple steps.

Why Does the Command Prompt Behave Differently After an In-Place Upgrade?

An in-place upgrade is a process that replaces the existing Windows operating system with a newer version, while preserving your applications, settings, and data. However, this process may also introduce some changes or conflicts in the system configuration, registry, or environment variables that affect the behavior of the command prompt.

One of the possible causes of the command prompt issues is that the policy that allows Windows 10 S to control Win32 applications has not cleared after the upgrade. This policy may prevent the command prompt from accessing the system32 folder or running certain commands.

Another possible cause is that the system files or the component store that the command prompt relies on are corrupted or modified during the upgrade. This may result in errors or access denied messages when you try to use the command prompt.

How to Fix the Command Prompt Issues After an In-Place Upgrade?

Depending on the cause and the severity of the problem, you may need to try different solutions to fix the command prompt issues after an in-place upgrade. Here are some of the common methods that you can use:

Solution 1: Restart the Computer

The simplest and most effective way to resolve the command prompt issues is to restart the computer after the in-place upgrade. This will clear any temporary files or settings that may interfere with the command prompt functionality. To restart the computer, you can use the following steps:

1. Click the Start button and select the Power icon.
2. Choose Restart from the menu.
3. Wait for the computer to reboot and log in again.

Solution 2: Check and Repair the System Files

If restarting the computer does not solve the problem, you may need to check and repair the system files that the command prompt uses. To do this, you can use the System File Checker (SFC) and the Deployment Image Servicing and Management (DISM) tools. These tools can scan your installation for errors and fix them automatically. To use these tools, you can follow these steps:

1. Open an elevated command prompt by typing command prompt in the search box on the taskbar, right-clicking the Command Prompt app, and choosing Run as administrator.
2. In the command prompt window, type the following command and press Enter: sfc /scannow
3. Wait for the scan to complete and check the results. If the scan finds and repairs any problems, restart the computer and try to use the command prompt again.
4. If the scan does not find any problems, or if it finds problems that it cannot fix, type the following command and press Enter: DISM /online /cleanup-image /RestoreHealth
5. Wait for the scan to complete and check the results. If the scan finds and repairs any problems, restart the computer and try to use the command prompt again.

Solution 3: Reset the Environment Variables

Another possible solution to fix the command prompt issues is to reset the environment variables that affect the command prompt behavior. These variables include the PATH, the COMSPEC, and the USERPROFILE variables. To reset these variables, you can use the following steps:

1. Open the Settings app by clicking the Start button and selecting the Settings icon.
2. Click System and then click About on the left pane.
3. Click Advanced system settings on the right pane.
4. In the System Properties window, click the Environment Variables button.
5. In the Environment Variables window, under the System variables section, select the PATH variable and click the Edit button.
6. In the Edit environment variable window, click the New button and type C:\Windows in the text box. Click OK to save the change.
7. Repeat the same steps for the COMSPEC variable and type C:\Windows\System32\cmd.exe in the text box.
8. Under the User variables section, select the USERPROFILE variable and click the Edit button.
9. In the Edit environment variable window, type %SystemDrive%\Users\%USERNAME% in the text box. Click OK to save the change.
10. Click OK to close the Environment Variables window and the System Properties window.
11. Restart the computer and try to use the command prompt again.
