What registry scanner? We have a tutorial to use the built in version but it is free.
I'll find the link in a moment.
The pay registry scanners/repair are a waste of money. Some were good for XP.
Most make Windows 7 worse by removing the wrong items causing more problems.
Option One in the tutorial.
This does not always work but many times it does. It will come to a point most likely that it will state it can't fix all the errors.
You will then run the repair again up to three times.
It usually takes up to three times to fix all errors if it can. SFC /SCANNOW Command - System File Checker
Also a repair install as I listed above will not lose your files, or photos etc.
Do a Repair installation if:
- A System Restore did not help fix your Windows 7.
- There is no other easier option left that can fix your Windows 7.
- You DO NOT want to do a Clean reinstall of Windows 7.
- You DO want to preserve your user accounts, data, programs, and system drivers.
