A Windows desktop cleaner for temporary files, browser caches, and local privacy traces. Review what your PC remembers, choose what to remove, and see the results before cleaning.
PCleaner can clear selected cookies, website identifiers, and other locally stored data. It does not block advertisements or network requests, and it cannot erase activity stored in your online accounts.
The screenshots below show the main workflow and the areas you can review before cleaning. The available rules and totals depend on the Windows account and browsers on the machine.
| Windows cleanup | Browser profiles |
|---|---|
 |
 |
| Area | Features |
|---|---|
| Windows | Temporary files, error reports, crash dumps, thumbnail and shader caches, and Microsoft Disk Cleanup handlers. |
| Applications | Selected graphics-driver and Microsoft application caches, plus supported recent-file lists. |
| Browsers | Profiles detected for Chrome, Edge, Brave, Opera, Vivaldi, Firefox, and other browsers in the browser catalog. Available rules depend on the browser family. |
| Privacy | Opt-in cookies, Chromium browsing history, form history, local addresses, website identifiers, and website storage. |
| Opened files | Opt-in Windows recent-file lists and supported editor sessions, including Notepad and Notepad++. |
| Review | Per-item explanations, target paths, file or database-entry previews, risk labels, and an activity log. |
The Privacy page includes Reset what sites know about me and Forget opened files selection presets. Review their selected items before cleaning: deleting cookies can sign you out, and clearing editor sessions can remove unsaved tabs.
PCleaner is built for Windows 10/11. Release packages target Windows x64.

Use Restart as administrator when you need system-wide items marked Admin. Save your work before closing applications for cleanup.
- Safe identifies regenerable caches and temporary data; these rules are selected on first run.
- Side effects identifies actions such as emptying the Recycle Bin or clearing saved sessions; these start unselected.
- Privacy identifies personal traces such as cookies and recent-file lists; these also start unselected.
Your choices are remembered. The engine uses explicit cleanup targets, a separate path-validation layer, protected browser-data lists, and checks for running applications. Temporary files younger than 24 hours are kept by default. These safeguards reduce risk; cleanup can still remove data you wanted to keep. See safety and scope before using advanced options.
On Windows, install the .NET 9 SDK selected by global.json, then run:
dotnet restore PCleaner.sln
dotnet build PCleaner.sln -c Release --no-restore
