Add Clean Reinstall Instructions

[ohjuny]

Closes #92 Added Reinstall instructions within Restart section.

Not 100% sure about the PowerShell commands, in particular whether the %APPDATA% and %USERPROFILE% aliases can be used literally. Do not have access to a Windows machine to test this.

I'd like to get somebody with a Windows machine to verify that I got the the paths right for WSL @melodell might be able to help?

Not a Windows person nor do I have access to one 😔

Not 100% sure about the PowerShell commands, in particular whether the %APPDATA% and %USERPROFILE% aliases can be used literally.

Will students be using Powershell? Then they can use:

PS > rm -rf "$env:APPDATA/Code"

If they'll be using WSL, then they can use:

$ APPDATA=`cmd.exe /c echo %APPDATA% 2> /dev/null | tr -d '\r' | xargs -0 wslpath`
$ echo $APPDATA
/mnt/c/Users/sesh/AppData/Roaming
$ rm -rf $APPDATA/Code

LMK if you have questions :)

Thanks for taking a look @seshrs ! A couple questions:

Is wslpath installed by default or would a student need to install a separate package?

Does wslpath have a simpler invocation, something like wslpath env | grep APPDATA or something?

[seshrs]

(Sorry I haven’t had a chance to reply yet, since I’m traveling for the next week. I think you’re right that this should be extra table without using wslpath. I’ll check this out again next week if you don’t get a chance to try it on a Windows laptop :) )

Checking in @seshrs . Thanks for your comments!

Sorry I didn’t return to this! Unfortunately I’m… uh… traveling again (😂) and won’t be near my Windows PC for another week lol

Looking at the command, I don’t think you really need wslpath in this invocation since it only appears to convert a Windows path to a WSL-compatible path.

In other words, almost all Windows users have the app data directory at /mnt/c/Users/<username>/AppData/Roaming. So maybe most people won’t need the programmatic solution to get the directory path.

If the question is simply about avoiding xargs, we could always direct students to copy the output from the CMD command, and paste it as an argument to wslpath :)

Thanks for the confirmation @seshrs ! I think this is good to go.
