So I should leave it like it is?None, Choose Wise Disk Cleaner or Built-in Windows Cleaning tools.
I have currently installed: Wise DiskCleaner, PerfectDisk & Revo Uninstaller. Should I replace Wise Disk Cleaner with WinOptimizer or Advanced SystemCare? Or leave the whole thing as it is?
Custom made uninstallers
Really, you should avoid anything that has adjectives in the description or title like: speed up, tune, optimize, enhance, boost, fix errors, increase this, increase that. No matter how flashy the graphics look or how many customer testimonials are posted.
I highly recommend ADW Cleaner, Combofix, RKill, and other similar utilities only be used under the supervision of BC staff or similar staff of other similarly high-quality forums. Reason for recommendation: these type of utilities are quite powerful and often are quite invasive -- unintended consequences can result if not run with precision, with specific purposes/goals in mind, cautiously, carefully. Anyone involved in such a DIY project ought to make sure backups are indeed restorable, or, that Windows install DVDs are close by.
