I tested Registry Distiller version 1.03 in Windows 8 and Windows 7 and didn’t have any issues. Free Error Cleaner is said to work in Windows 7, Vista, and XP. The Windows registry is backed up automatically before fixing any issues, and restoring is just a couple clicks away. I successfully used Free Window Registry Repair to clean up the registry in both Windows 10 and Windows 7.
While testing this program, it seemingly found many more problems than most of the other programs in this list. The registry is wikidll.com/other/dsetup-dll automatically backed up, so there’s no need to do it manually. MV RegClean looks very outdated, and it may very well be, but it seems to do well with deep registry cleaning. Vit Registry Fix works with Windows 10, 8, 7, Vista, and XP.
Also, theDeep Cleanoption requires the professional version of the program. One thing I don’t like about Advanced SystemCare is that if you’re after a particular cleaning type, like registry cleaning, you must first uncheck all the other options. All the features that are offered can be overwhelming and get in your way. I tested CCleaner v5.68 using both their portable and installable versions on a 64-bit version of Windows 10 and Windows 8.
One thing I didn’t like about this program is that it’s a little confusing to know which registry items you’re going to remove and which will stay intact. Only one option is available with Registry Fixer, which is to back up the registry before cleaning. Registry Distiller is said to work in Windows Vista and XP.
