如何修复 Git bash 无法在 Windows 上工作

Question

I uninstalled a few apps in control panel, then my git bash stopped working.

I think its related but not sure what it might be that made it stop. When I run bash outside of vscode i get the following (screenshot)

The only apps I remember uninstalling were Windows SDK tools and Visual Studio Installer.

I tried re-installing git bash but I still get the same error.

I get the following error in vs-code terminal

Here is the fix.

1. Go to you Windows Defender Security Center settings
2. Click on App & Browser Control
3. At the bottom click on the "Exploit Protection Settings" link
4. Go to "Program Settings" and click on the "Add program to customize" -> "Choose exact file path"
5. Navigate to "C:\Program Files\Git\usr\bin\sh.exe" and add it
6. Override and turn off the following: Mandatory ASLR Randomize memory allocations (Bottom-up ASLR)
7. Click "Apply" and now everything should work fine.

Also add these other binaries from the same folder: expr.exe, uname.exe, grep.exe, rm.exe

Good luck, Gabriel
