  2. Scan the Registry
  3. Clean Boot Windows
  4. Reinstall Microsoft NET Framework

1. Run a System File Checker Scan

Corrupt system files are a probable source for the Event ID 1000 application error. As such, the System File Checker could feasibly resolve the issue. System File Checker is a Windows utility that scans for corrupted WRP system files and repairs them. This is how you can scan with the SFC utility in Windows 10.

  • Open the Win + X menu with the Win + X hotkey.
  • Click Command Prompt (Admin) to open an elevated Command Prompt.
  • First, input ‘DISM.exe /Online /Cleanup-image /Restorehealth’ and press Enter. That will repair the .wim store for the System File Checker if required.
  • Then you can enter ‘sfc /scannow’ in the Command Prompt, and press the Return key.

  • Expect the scan to take about half an hour. Restart Windows if the scan repairs system files.

2. Scan the Registry

The Event ID 1000 error might also be due to corrupted registry entries. So a registry scan with reputable registry cleaner software might also fix the issue. Glary Utilities, Iolo System Mechanic and CCleaner are three highly rated registry cleaners that millions of users scan with. You can scan the registry with the freeware CCleaner as follows.

  • To add the freeware CCleaner to Windows, click the Download button on this webpage. Then open the software’s setup wizard to install CCleaner.
  • Open CCleaner and click Registry on the software’s window.
  • Select all the registry check boxes, and press the Scan for Issues button.

Clean registry errors

  • Next, select the Fix selected Issues option. You can also select Yes to back up the registry beforehand, but you probably won’t need the backup.
  • Then click Fix All Selected Issues to fix the registry.

3. Clean Boot Windows

Software conflicts can often crash programs. So, a clean boot might help fix the Event ID 1000 error in Windows. That boots Windows with minimal startup software and drivers. You can clean boot Windows 10 as follows.

  • Press the Windows key + R hotkey to open the Run accessory.
  • Then you can input ‘msconfig’ in Run to open the System Configuration window below.

  • Select the Selective startup option on the General tab.
  • Select both the Load system services and Use original boot configuration options.
  • Deselect the Load startup items check box.
  • Then select the Services tab shown in the snapshot directly below.

4. Reinstall Microsoft NET Framework

NET Framework is a developer framework that is essential for some software. So the Event ID 1000 error can be due to a NET Framework version that needs fixing. Thus, reinstalling NET Framework is another resolution for the Event ID 1000 error. You can reinstall Microsoft NET Framework in Windows 10 as follows.

  • First, open the Run accessory.
  • Input ‘appwiz.cpl’ in Run’s text box, and click the OK button.
  • Note that earlier Windows platforms include Microsoft NET Framework on the Uninstall or change a program list. If you can see Microsoft NET Framework listed there, select it and press the Uninstall button.
  • In Windows 10, you’ll need to click Turn Windows features on or off to open the window in the snapshot below.

  • Expand the listed NET Framework components listed there and deselect all their check boxes.
  • Next, click Download on this page to save the NET Framework Cleanup Tool’s ZIP to Windows.
  • Open the NET Framework Cleanup Tool ZIP in File Explorer and press the Extract all button to extract it.
  • Open the NET Framework Cleanup Tool’s window shown in the snapshot below.

  • Press the Cleanup Now button.
  • Then restart the Windows OS.
  • Download the NET Framework 4.7 version from this page, and then install it.

Before reinstalling NET Framework 4.7, check out the Microsoft NET Framework Repair Tool. That’s a utility which fixes NET Framework issues, so it might also resolve Event ID 1000 errors. You can download the NET Framework Repair Tool from this webpage. Then open the utility’s window and press its Next button to fix NET Framework.

5. Update Windows Drivers

Driver Booster 5 pro

Outdated drivers can be another factor behind Event ID 1000 errors. To quickly scan drivers, add Driver Booster 5 to Windows by clicking Free Download on this page. Then, when you launch the software, it will scan and list outdated drivers. Click the software’s Update Now button to update outdated drivers.

  • Input ‘appwiz.cpl’ in Run, and press the OK button.

  • Then select the program that is crashing.
  • Press the Uninstall button.
