NirLauncher is a suite of almost 200 of NirSoft's excellent portable freeware Windows utilities, and provides an interface that makes it easy to find and launch the tools you need. Which works for us - because there's something here for everyone.
Have you forgotten a password stored in your browser or email client, for instance? Recovery tools here may be able to find them for you.
Maybe you'd like to check your hard drive health? A disk tool will display its S.M.A.R.T. data (if the drive supports this), so you can view read/ write errors, temperature and other useful details.
Is your system unstable? The System Utilities section includes several tools that can help to explain why your PC might be crashing.
And there are a host of other programs on offer in categories like "Network Monitoring", "Web Browser Tools", "Video/ Audio Related Utilities", "Outlook/ Office Utilities" and more.
Please note, perhaps because a few of these tools can be used maliciously (the password revealers, say), some antivirus programs will flag them as threats. We've never had a problem with any NirSoft tool, though, and you can read more on this issue at the author's site.
IMPORTANT: we've had to remove NirLauncher from our download servers as Google mistakingly flags it up as 'malware'. The download link here now points to the NirLauncher website.
