Win11 Toggle Rounded Corners: baixar versões antigas

Fixes the logon task on multi-user PCs and laptops.
New
- The installer asks whether the logon task should apply to every administrator on the PC
or only to the account running setup.
Fixed
- The logon task only ran for the account that installed it. Anyone else signing in got
rounded corners back with nothing to explain why. It now covers every administrator on
the PC. (thanks @bughit for reporting!)
- Laptops signing in on battery skipped the task entirely, because it was inheriting the
schtasks default that blocks tasks on battery power.
Standard accounts still aren't covered: the patch needs administrator rights, and a
scheduled task can't elevate a standard account.
Full Changelog: v1.3...v1.4

Adds automatic elevation, a smaller-corners option, and a modernized codebase.
New
- The tool now requests administrator rights on launch, so starting it from Explorer, a
shortcut or the installer brings up the standard UAC prompt instead of failing with
"make sure you are running as admin". Note that every invocation now needs elevation,
including --help.
- --small option for a subtler alternative to fully square corners (thanks @amnweb!)
Changed
- Failures now say what actually went wrong. Where v1.2 printed status: 0x5, you now get
Access is denied. (0x5), with the Windows error text alongside the code.
- The installer now tells you when the "run automatically on logon" scheduled task could
not be created, instead of leaving it silently missing.
Removed
- The --no-patching fallback. It pulled in Zydis (a full x86 disassembler) just
for this one option, inflating the binary for a niche feature with worse visual
results than the primary .rdata patching method, which has been the default
all along and is now the only option. If you'd rather keep using it, v1.2 still
has it. Normal usage (--disable/--enable/--small) is unaffected.
Under the hood
- Modernized the codebase to C++23/26.
- Opens dwm.exe with just the memory read/write access the patch needs, rather than
requesting full access to the process.
- Every Win32 handle is now owned by an RAII guard instead of being closed by hand on each
exit path, so the process handle, snapshot, token and loaded module are all released even
when an error cuts the patch short.
- Builds are now reproducible and carry a signed build-provenance attestation via
GitHub Actions. Verify a download with:
gh attestation verify <file> -R rich-ayr/win11-toggle-rounded-corners
- Formatting is enforced in CI with clang-format.
