PC Tweaker 0.3.0 adds real disk tools (Optimize drive, Flush DNS cache, Find large files, Drive health), a proper multi-drive picker, and a smaller native-style toggle switch.
Existing download links still work. v0.2.0 and v0.1.1 remain published and downloadable.
New
Optimize drive — runs Windows' own built-in optimizer: TRIM on an SSD, defragmentation on an HDD, never a full defrag pass on an SSD (which would only wear it out for no benefit). Requires administrator rights, one UAC prompt.
Flush DNS cache — clears cached DNS lookups. Free, no elevation needed.
Find large files — scans a folder for its biggest files (over 100 MB) so you can quickly free up space. Same scan → select → move-to-Recycle-Bin flow as the existing duplicate finder, but by size instead of content — a single large forgotten file has no duplicate to find, but is easy to spot once sorted by size.
Drive health — reads Windows' own S.M.A.R.T./reliability status for the selected drive.
A real drive picker — Drive health and Optimize drive now work against any fixed drive on the machine, not just the system drive.
Changed
- Toggle switches are now a compact pill with an "On"/"Off" caption, matching Windows 11's own Settings app, instead of a larger iOS-style switch.
Fixed
- "Optimize drive" could silently fail for real users. The first version called
defragdirectly without going through the app's elevation flow — it only worked when the app process happened to already be running elevated. A normal, unelevated install would have failed outright with no UAC prompt ever shown. Now wired through the same proven single-UAC-prompt pattern used everywhere else in the app. - Roughly 30 leftover Italian error strings on rarely-hit failure branches across several Rust modules — the same class of issue fixed for tweak names in 0.2.0, missed in the error-message paths at the time.
Under the hood
31 Rust unit tests (up from 24), including drive-enumeration tests that run against the real disks on the build machine.
Install
Download pc-tweaker-app_0.3.0_x64-setup.exe (recommended) or the .msi. Windows 10/11, 64-bit.
The installer is not code-signed yet, so SmartScreen shows "Windows protected your PC" on first run — click More info → Run anyway.
