mise updates the shim in winget links, but refers to shim in winget packages + installed shim misses version tag

[iki]

Steps to reproduce on Windows

1. Install jdx.mise using winget + optionally create the missing mise winget links, see mise winget package does not create links for mise and mise-shim properly #14735

 winget install -e --force --silent --accept-package-agreements --accept-source-agreements --id jdx.mise
ln -sfvT "%LocalAppData%/Microsoft/WinGet/Packages/jdx.mise_Microsoft.Winget.Source_8wekyb3d8bbwe/mise/bin/mise-shim.exe" "%LocalAppData%/Microsoft/WinGet/Links/mise-shim.exe"
ln -sfvT "%LocalAppData%/Microsoft/WinGet/Packages/jdx.mise_Microsoft.Winget.Source_8wekyb3d8bbwe/mise/bin/mise.exe" "%LocalAppData%/Microsoft/WinGet/Links/mise.exe"

2. Run mise self update:

>>> mise self-update -y
Selected mise 2026.10.13 (minimum release age: 1d)
mise is already up to date
plugin:eza       update git repo                                                                                                                               ✔

3. Check mise executables and links:

>>> where mise mise-shim.exe
%LocalAppData%\Microsoft\WinGet\Links\mise.exe
%LocalAppData%\Microsoft\WinGet\Links\mise-shim.exe
>>> fd -gl mise*.exe "%LocalAppData%\Microsoft\WinGet"
-rwxr-xr-x 1 iki 197121 271K Oct 19 13:42 'C:\Users\iki\AppData\Local\Microsoft\WinGet\Links\mise-shim.exe'
lrwxrwxrwx 1 iki 197121  117 Jul 26 21:32 'C:\Users\iki\AppData\Local\Microsoft\WinGet\Links\mise.exe' -> $LocalAppData/Microsoft/WinGet/Packages/jdx.mise_Microsoft.Winget.Source_8wekyb3d8bbwe/mise/bin/mise.exe
-rwxr-xr-x 1 iki 197121 234K Jul 23 01:05 '%LocalAppData%\Microsoft\WinGet\Packages\jdx.mise_Microsoft.Winget.Source_8wekyb3d8bbwe\mise\bin\mise-shim.exe'
-rwxr-xr-x 1 iki 197121 208M Oct 19 13:42 '%LocalAppData%\Microsoft\WinGet\Packages\jdx.mise_Microsoft.Winget.Source_8wekyb3d8bbwe\mise\bin\mise.exe'

Expected: mise-shim is updated in winget packages, link is kept (exactly like done properly for mise.exe)
❌ Result: shim link is replaced with updated version, and shim in winget packages is not updates (stays on old version)

4. Copy new mise shims to winget packages manually and link it from winget links:

>>> cp -fvT "%LocalAppData%/Microsoft/WinGet/Links/mise-shim.exe" "%LocalAppData%/Microsoft/WinGet/Packages/jdx.mise_Microsoft.Winget.Source_8wekyb3d8bbwe/mise/bin/mise-shim.exe"
>>> ln -sfvT "%LocalAppData%/Microsoft/WinGet/Packages/jdx.mise_Microsoft.Winget.Source_8wekyb3d8bbwe/mise/bin/mise-shim.exe" "%LocalAppData%/Microsoft/WinGet/Links/mise-shim.exe"

5. Run mise reshim

>>> mise reshim
WARN  mise-shim.exe at %LocalAppData%\Microsoft\WinGet\Packages\jdx.mise_Microsoft.Winget.Source_8wekyb3d8bbwe\mise\bin\mise-shim.exe is older than mise 2026.10.13: it has no version tag, so it predates this check
shims copied from it keep the old launcher, however often `mise reshim --force` runs
update mise with the package manager that installed it (or `mise self-update`) so mise-shim.exe is replaced too, then run `mise reshim --force`

Expected: mise reshim has current version of the shim in winget packages and has no reason to complain
❌ Current: it still complains about missing mise-shim.exe version tag, even if it's a current shim

Thanks for the detailed repro. The first half is a bug: mise self-update wrote the new mise-shim.exe next to the mise.exe you launched it through (the WinGet\Links symlink). That replaced the mise-shim.exe link with a plain copy and left the real shim in the winget package directory on the old version. jdx/mise#14737 resolves mise.exe to its real path first, so the package copy is updated and the link stays.

The mise reshim warning about a missing version tag is probably a side effect of the stale shim, since reshim looks for the shim beside the real mise.exe. Once #14737 ships, mise self-update followed by mise reshim --force should clear it. If it still warns, please say so here.

Implemented in #14737: fix(self-update): update mise-shim.exe beside the real mise.exe, not a link to it

Awesome 🔥 Thank you!

One note: the warning is not related to stale shim. I copied the shim updated by mise self update from winget links to winget packages (and restored the link) in step 4 above. The shim file time is the same as mise.exe time and it was installed with the same release. Is there a possible bug in the shim distributed with 2026.10.13?

Verification:

Fixed in v2026.10.17 by #14737. Update with mise self-update or see the install docs.
