Is your C: drive full of leftovers that Disk Cleanup leaves behind? DiskMax, a free cleaner by Koshy John, digs deeper: update rollback files, DLL caches, event logs and old dump files go along with the usual temp files and browser traces.
Scan for removable files
A scan covers the Recycle Bin, installer remnants, debugging data, temp and temporary internet files, Windows caches, help-center caches, repair information, DLL caches and Windows Update rollback files.
An optional deep scan also searches the drive for stray LOG, OLD, BAK, TMP, CHK, SWP and DMP files.
Clear Windows and browsing clutter
On the privacy side it removes cookies, browsing and user history, recently opened document lists, the Explorer thumbnail cache, internet logs and error-reporting logs.
Windows event logs can be cleared as well. Keep in mind that removing update rollback files means installed updates can no longer be uninstalled.
Scan and fix the Windows registry
In the registry, DiskMax clears Most Recently Used lists, the traces Windows keeps of files and commands you opened.
It is still maintained: version 7.33 came out in June 2026 for 64-bit Windows 10 and 11, and it must run from an administrator account.
Pros
