The file dnscacheugc.exe is not a standard, legitimate Microsoft Windows system file. It is highly likely associated with malware, adware, or a coin-miner that has disguised itself using a name similar to the legitimate Windows DNS Cache service (dnsrslvr.dll or svchost.exe).

To fix errors related to dnscacheugc.exe without downloading third-party repair tools, you need to manually remove the file and its startup triggers using built-in Windows utilities.

Step 1: Terminate the Process in Task Manager

Before deleting the file, you must stop it from running.

Press Ctrl + Shift + Esc to open Task Manager.
Click on the Details tab (or Processes tab in older Windows versions).
Look for dnscacheugc.exe in the list.
Right-click the process and select Open file location. Note this folder path.
Go back to Task Manager, right-click dnscacheugc.exe, and select End task.

Step 2: Delete the Executable File

Navigate to the folder path you noted in the previous step.

Select the dnscacheugc.exe file.
Press Shift + Delete to permanently delete the file without sending it to the Recycle Bin. Note: If the file is located in C:\Windows or C:\Windows\System32, be careful not to delete any other files, as this is a common hiding spot for malware.

Step 3: Remove the Startup Trigger via Registry Editor

Malware often creates registry keys to restart itself automatically when Windows boots.

Press Windows Key + R, type regedit, and press Enter to open the Registry Editor.
Navigate to the following two paths by pasting them into the address bar at the top:
- HKEY CURRENT USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY LOCAL MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
In the right pane of these folders, look for any entry pointing to dnscacheugc.exe.
Right-click the entry and select Delete.
Close the Registry Editor.

Step 4: Run Built-In Windows Defensive Tools

Use Windows' built-in security features to clean up any remaining registry corruption or hidden files.

Press the Windows Key, type Windows Security, and press Enter.
Click on Virus & threat protection.
Click on Scan options, select Microsoft Defender Antivirus (offline scan), and click Scan now. Your PC will restart and scan for deeply hidden malware without needing an internet download.
After the restart, press Windows Key + X and select Terminal (Admin) or Command Prompt (Admin).
Type sfc /scannow and press Enter to repair any system files corrupted by the file.

To help ensure your system is completely clean, let me know:

What specific error message are you seeing (e.g., "File not found", "Application error")?
What folder path did the file location lead you to?
Is your computer experiencing high CPU usage or general slowness?
