Task Manager keeps crashing after switching to detailed view Windows 10

Based on the hint provided about the registry quotes that are wrong. I've looked into the registry and found and fixed the problem.

Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

Look at the key for Claude and you can see that the start up key is wrong.

Claude installs the key with the value:

"\"C:\Users\comet\AppData\Local\AnthropicClaude\claude.exe\" --startup"

But it should be

"C:\Users\comet\AppData\Local\AnthropicClaude\claude.exe" --startup

I explicitly urge anyone to not use any of the answers below. Those are like using a nuclear bomb to take out pea shooter.

Because support for Windows 10 has ended, the troubleshooting steps available are limited, the best option is to perform an in-place repair with the Windows 10 ISO.

Please ensure you download the ISO in the same language as you use for the Windows UI, follow the steps, this is then not like re-installing Windows, it is just like an update and your personal files, settings and installed software will not be affected.

Click this link:

https://www.microsoft.com/software-download/windows10

to download the Media Creation Tool (Click on Download Tool Now), with that you can download the latest Windows 10 ISO (Select Create Installation Media for Another PC), then choose ISO, not USB

When the ISO file completes downloading

Disconnect from the Internet

Disconnect all external devices with the exception of a mouse or keyboard.

Temporarily disable any 3rd party Anti-virus you may have installed

Then, in Windows File Explorer, double click the ISO and then run Setup.exe and select the Install option.

Very Important - ensure you select the option to keep your files and apps.

The crash report shows Taskmgr.exe (Task Manager) is failing with exception code c0000005 (access violation). This is consistent with a known issue where Task Manager can leave background instances running or become unstable after UI changes.

Use these steps to mitigate and restore stable behavior:

1. Terminate all Task Manager instances
   • Open an elevated Command Prompt (Run as administrator).
   • Run a command that ends all running Taskmgr.exe processes (as described in the Windows 11 known-issues workaround). This clears any hidden or stuck instances that may be corrupting state when switching views.
2. Repair system files
   • Run sfc /scannow from an elevated Command Prompt to verify and repair Taskmgr.exe and related system components.
   • If SFC reports repairs, restart Windows and test Task Manager again.
3. Apply latest Windows updates
   • Install all pending Windows 10 updates. Microsoft uses cumulative updates to ship fixes for shell and management tools; similar crash and freeze issues (for example, Explorer.exe and Secure-Boot-Update tasks) have been mitigated by updates in the past.
4. Check for third‑party conflicts
   • If Task Manager only crashes after switching to the detailed view, temporarily disable or uninstall any shell extensions, performance overlays, or OEM utilities that integrate with process lists (for example, vendor “Vantage” or monitoring add‑ins shown in Reliability Monitor).
   • Reboot and test Task Manager after disabling them.
5. If crashes persist, use an alternative until a fix arrives
   • Use Resource Monitor (resmon.exe) or Get-Process in PowerShell for process inspection until a future cumulative update addresses the crash.

These steps align with how similar reliability issues (Explorer.exe crashes, Windows Runtime/App crashes, and scheduled-task freezes) are mitigated: terminate stuck processes, repair system files, and keep Windows fully updated while Microsoft rolls out permanent fixes.
