Searching for answers, I found mixed reviews on Trustpilot and Cnet . While some users praised the quick speed boost, many others warned of system instability. Experts on Microsoft Community forums often advise against these types of deep-registry cleaners, suggesting that Windows is better at managing itself than third-party tools.

But the honeymoon didn't last. By Tuesday, my printer stopped connecting. By Wednesday, my favorite photo editor wouldn't launch because of a missing ".dll" file. I realized the software hadn't just cleaned my registry; it had performed surgery with a chainsaw.

The morning started with a familiar frustration: my PC was crawling, and the "blue screen of death" had become a weekly visitor. Desperate for a fix, I stumbled upon a tool called WiseFixer. It promised to scrub my registry and restore my computer to its former glory.

Does it happen during or while using a specific app ? Which version of Windows are you running?
