Windows 7 taskmanager parameter incorrect

1. Check User Account Control (UAC) Settings:​

• Make sure that the User Account Control (UAC) settings are not preventing you from opening Task Manager.
• You can adjust the UAC settings by going to Control Panel > User Accounts > User Accounts > Change User Account Control settings.
  

  2. Run Task Manager via Command Prompt:​

  You can try running the Task Manager using the command prompt. Here's how:
• Open Command Prompt by searching for it in the Start menu.
• Type the following command and press Enter:
  Code:

   taskmgr

  3. Check System File Integrity:​

• Open Command Prompt as an administrator.
• Run the System File Checker (SFC) tool to check for system file integrity issues by executing the command:
  Code:

   sfc /scannow

  This command will scan and repair any corrupted system files.
  

  4. Create a Shortcut for Task Manager:​

  If the issue persists, you can create a desktop shortcut for the Task Manager:
• Right-click on an empty area of your desktop.
• Select "New" and then "Shortcut."
• In the location field, type:
  Code:

   taskmgr

• Click "Next" and give the shortcut a name.
• Click "Finish" to create the shortcut.
  

  5. Check for Malware:​

  It's recommended to run a virus scan on your system to ensure that malware is not causing the issue. If none of these solutions work, it might be beneficial to update to a newer version of Windows as Windows 7 x64 Build 7100 is an older release. Feel free to try these steps and let me know if you encounter any issues or if you need further assistance!
