Why Does Blue Scree With Powershell Some Up Everytime I Start Computer
Why PowerShell Opens On Start-up and How to Stop It
The reason PowerShell open on Startup is likely because you mistakenly added Windows PowerShell shortcut to the Start-up folder.
If you also look at the Start-up tab of Task Manager, Windows PowerShell will be listed and status displayed as Enabled.
Moreover, there may be other reasons PowerShell may open on startup. In the next section, I have offered additional reasons this may be happening and options to fix the problem.
How To Stop PowerShell From Opening On Startup
There are several methods to stop PowerShell opening at startup. In this section of the guide, I have listed fixes you could try…
1. Disable PowerShell Startup Status From Task Manager
- Right-click an empty spot on the task bar. Then, from the displayed options, click Task Manager.
- When Task Manager opens, click the Start-up tab.
- Finally, on the task manager, Start-up tab, right-click Windows PowerShell and select Disable.
2. Delete Windows PowerShell Shortcut From Startup Folder
As I mentioned in the introduction of this Itechguide, the reason PowerShell opens on Startup is if you mistakenly copied the shortcut to the start-up folder. To stop it, use the steps below to delete the shortcut.
- Enter %ProgramData%\Microsoft\Windows\Start Menu\Programs\StartUp in the Windows 10 search. Then, click the folder.
- When the start-up folder opens, delete the Windows PowerShell shortcut.
Once you delete the shortcut from the Start-up folder, it will no longer be available in Task Manager Start-up tab.
3. Use Autoruns Program To Check If PowerShell Auto-starts Somewhere Else
There is a tiny program on Microsoft's site called Autoruns for Windows v13.100. This program lists all applications configured to run during computer bootup or login.
If PowerShell is configured to open on startup somewhere else, this program should be able to detect it.
Follow the steps below to install and use Autoruns:
- Open Autoruns for Windows v13.100 link.
- Then, just before the Introduction section, click Download Autoruns and Autorunsc. Clicking the link downloads a zip file.
- Open the location of the downloaded zip file. If you downloaded the zip file with Google Chrome, on the bottom left of your browser, click the arrow beside the file. Then, select Show in folder.
- When the location of the zip file opens, right-click it. Then, select Extract All…
- On the first screen, click Extract. The file will unzip and automatically open a folder called Autoruns.
In the next steps, you will run the program and it may be able to show you if PowerShell is set up to open on startup somewhere else on your computer. The beauty of this tiny program is that it also checks the Windows registry!
- To run the program, click Autoruns and wait for it to load auto-run entries.
- Finally, enter powershell in the Filter field. If PowerShell is configured to auto-open on startup, it will be displayed. To disable the auto-start entry, uncheck the checkbox beside it.
Alternatively, if nothing is displayed, it means that PowerShell is not set up to auto-start anywhere in the registry. In this instance, you can try the next 2 recommendations…
4. Scan Your Computer With CCleaner
Since there may be other unknown reasons PowerShell may be opening on startup, the next step is to run a program called CCleaner.
CCleaner finds problems on your computer and recommends fixes. If your computer is acting weird, like opening PowerShell randomly, running CCleaner may help fix it.
The first step is to open the CCleaner download page. Then, scroll down to the free options and click Download. Once the program is downloaded, install it.
Warning!
When installing the program, please select Custom installation and make sure not to agree to install other programs they will suggest. Otherwise, you will end up installing a bunch of unwanted programs. Do not panic though, CCleaner is a very safe program. We use it on itechguides.com and it is safe!
Once you have installed CCleaner, follow the steps below to use it to scan your computer…
- Enter CCleaner in the Windows 10 search and open the application from the search result.
- On the first screen, CCleaner will recommend that you perform a PC health check. Click Skip to start health check.
The next step will close your browser. You may want to open this guide on a different computer. If you do not have another computer, you may open the guide on your phone. However, you can decide to skip the browser cleanup as it is nothing to do with PowerShell opening at startup – see the next step for details.
- If you have any browsers open, CCleaner will request your permission to close them. If you are happy to close your browsers, click Close & Analyze.
However, if you do not want to close your browser, uncheck it from the list. Then, click Skip All – see the second screenshot below…
Now wait for CCleaner to scan your computer for errors.
- When CCleaner returns its recommendations, click Make it better. Then, wait for the application to fix the problems it found on your computer. See the second screenshot below…
When this stage is completed, you need to perform registry cleanup. See step 5 below.
- To perform registry cleanup, on the left pane of the application, click Registry.
The following steps may break your computer. Proceed with caution.
- Then, on the Registry Cleaner screen, click Scan for Issues. Then, wait for the registry scan to complete.
- Finally, when CCleaner completes the registry scan, at the bottom right, click Review Selected Issues.
- You will be prompted to backup the registry. Select Yes.
- Save a copy of the registry and note the location.
If your computer breaks, you will need this to fix it!
- Click Fix All Selected Issues. When it finishes, click Close.
- Finally, restart your computer. When it starts, check if PowerShell still opens on startup. If it still opens on startup, try the last 2 recommendations below…
5. Scan Your Computer With Malware Removal Tool
If after applying the last 2 recommended fixes, if PowerShell still opens on startup, it is possible that your PC is infected with malware.
We have a guide that explains How to Remove Malware from Windows 10 (link opens in a new browser tab – explains how to remove malware from your Windows 10 PC).
6. Uninstall Windows PowerShell Completely
If you have tried all the 5 fixes above and PowerShell still opens on startup, you may want to consider uninstalling it. After all, if you are not a Systems administrator, you may not need PowerShell.
To uninstall PowerShell, open Command Prompt as administrator. Then, enter the command below into command prompt and press enter key on your keyboard.
Dism /online /Disable-Feature /FeatureName:"MicrosoftWindowsPowerShellV2Root"
Wait for the command to finish. Then, restart your computer.
