RegCleanr is a fabulous registry cleaner, when you can get the file to execute. I have been using this for years, but have recently run into issues with the exe file not responding properly to Open, Run, and Run as commands. If I remember correctly, it is NOT a Microsoft file.
@Bramble_Talonshire: Could it be possible that u r using a Dualcore CPU (or Hyper-threading Pentium)? If that's the case, try to bring ur cpu to a short peak (e.g. seach sth in your registry with regedit) and then start regcleanr, then open the taskmanager and mark regcleanr's process to be handled by only one of your CPUs^^
I have been using this file by Jouni Vuorio and distributed as freeware,however he joined with RegSumpreme, which is much the same program, with a little bit different infterface. As with any uninstall you get a lot of files on your computer which you can delete under the software tab. I would recomment this software to anyone if you can still find it.
Very useful program.Not so good on dualcore cpu-s,but it can be started.
This RegCleanr program suite has been working very well for me for over 5 years. When XP is doing strange things, the Cleanr is able to get rid of unwanted molesters including gratuitous start ups.

Best practices for resolving RegCleanr issues

A clean and tidy computer is the key requirement for avoiding problems with RegCleanr. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the RegCleanr.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
