Advanced Systemcare 15 Pro Crashed OS

[BobB461]

I have ASC v15 Pro. Every time I do a full scan, my Windows 10 Dell laptop will not boot up properly, and Windows will run its recovery program, “Attempting Repairs”. This recovery will take a hour+ or so to repair my OS boot up. This only occurs when it scans and “fixes” the registry. 
im reluctant to run ASC for fear of it totally crashing my system. Recommendations?

Check your Registry Clean settings. If the Enable Deep Clean option is ticked, then untick it.

That option can be too aggressive when cleaning the registry.

Let us know if that solves the issue.

Also it is unnecessary to avoid using ASC, as you can simply untick the registry clean option on the Scan page.
