Clean computer registry files

Sorry this didn't help. Thanks for your feedback. Use of registry cleaners is generally not supported, as they can cause more problems than a average user can deal with, they have been known to brick PC,s.

Using a registry cleaner is like, well, allowing a stranger onto your PC thru Remote Assistance I know I would not , because you do not know what they are likely to do!!!! Don't use it. I haven't being using a very popular cleaning-program for some years now, just for testing, how this will go, because of the advices in here, and the computer runs like a charm.

This very popular cleaner-program, only free up a few MB space on your harddisk, so it's not worth to waste time with! The only cleaner-program, I use, is Windows own Diskcleanup and Cleanup systemfiles, or in a command Prompt, runned like administrator, I just write cleanmgr, and mark everything except the Recycle Bin, which I want to run by my self.

But is there anything, we should'nt cleanup in Windows 10's Cleanup systemfiles? Something, we should leave alone? I only runs Windows 8. How do I clean Registry in Windows This thread is locked. You can follow the question or vote as helpful, but you cannot reply to this thread. None of the cleaners managed to fix a gnarly problem with spoolsv. We focused on their ease of use, the number of errors found, and whether they introduced any hazards, such as the lack of automatic backups before making changes.

And except for Registry First Aid, none of the products would repair faulty entries, but instead just deleted entries that were no longer valid. Registry First Aid is eager to help you fix and tidy your registry—and it does a terrific job, too. Of all the programs tested here, this one inspired the most confidence, both from a safety perspective and in the way it handled registry problems.

The interface is clean and easy to navigate, and the program includes a registry searching tool, a backup and restore tool, the ability to take snapshots of the registry, and a compression tool. Registry First Aid supports all versions of Windows. We were comfortable with the way it listed problems, either by category such as invalid file or DLL, invalid path, or unused software entries or by safety level.

We could cut the invalid substring or, in some cases, repair the entry. While the program was scanning, we were able to examine each listing, check or uncheck it, or open the specific entry in the registry.

One quibble: The tool attempted to find a home in the system tray, unnecessarily adding clutter just so it could regularly check for new versions. We disabled it in the settings. It includes a registry cleaner as well as a registry compactor along with a few other administrative tools, and is essentially a scaled-down version of its bigger sibling, jv16 PowerTools see below.

In RegSupreme Pro you can set it to scan either quickly or safely, or somewhere in between you slide a bar along a scale.

RegSeeker is free for personal use and has a handful of other registry-focused utilities. The tools include a keyword finder; a utility to examine installed application registry entries, assorted histories for instance, browser and Start-menu items , and Startup entries; and a tool to tweak more settings.

It supports Windows XP, Vista, 7, 8, and Advanced WindowsCare is a freebie beware of Yahoo bloatware during the install though and comes with other tools besides a registry cleaner. For instance, it claims to deter and remove spyware, optimize your PC, manage your Startup items, and remove junk files.

Though Advanced WindowsCare found registry issues, its presentation of the scanning results was pitiful. Unlike other tools that supplied detailed information about each problem, a choice of fixes, or a way to open the registry to see the actual entry, Advanced WindowsCare just showed us a list.

The program uses a minimalist approach: Each item sports a cautionary symbol with no legend , the registry key location and an error description obsolete software key or missing MUI reference, for instance.

Not good. The program supports Windows , XP, and Vista officially but we had no trouble running it onWindows 10, however we only recommend it to advanced users.
