PowerShell 7.2.6 output weird text in console and beeps

[Mingun]

Type: Bug
This question describes situation. After my PC hung and rebooted the VSCode suddenly starts output weird text in integrated terminal and beep each time when command is started/ended. The output looks like:

←]633;C
←]633;E←]633;D←]633;A←]633;P;Cwd=D:\Projects\quick-xmlPS D:\Projects\quick-xml> ←]633;B

I tried all suggested anwsers on SO, restarting VSCode after each attempt, but nothing worked:

• I tried to reinstall PowerShell 7
• terminal.integrated.windowsEnableConpty is true. I tries to set it to false
• I tried to install PowerShell extension and run both PowerShell: Disable ISE Mode (restore to defaults) and PowerShell: Enable ISE Mode

When I run pwsh.exe, none of that weird text appeared. I have nothing of those files:

Thanks for creating this issue! It looks like you may be using an old version of VS Code, the latest stable release is 1.71.0. Please try upgrading to the latest version and checking whether this issue remains.

Happy Coding!

[Mingun]

I cannot install 1.71.0 because I'm on Windows 7 and support of Windows 7 was dropped in 1.71.0

[meganrogge]

setting terminal.integrated.shellIntegration.enabled to false should fix this for you

[Mingun]

Thank you!!! That works!

[Tyriar]

Looks like this is Windows 7, so I don't think shell integration works using winpty. Reopening as we should disallow shell integration injection when conpty is not being used.

[alexr00]

What is the best way to verify this?

[Tyriar]

This is probably best to do via an extra code review. If you have access to a Windows 7 machine, you can enable the shell integration setting, open pwsh and make sure the sequences don't show up.

[Mingun]

But how to do that on Windows 7 considering that VSCode is no longer updated on Windows 7?

[Tyriar]

@Mingun good point, Windows 8 or a old version of Windows 10 would also work. Any version before we support conpty (>= build 18309)
