Monitor PC Health Right On The Desktop

It's useful to have easy access to key information about your PC, so you can keep it running efficiently and get to grips with any problems.  Rainmeter is a useful program which displays such information, and you can customise which data gets displayed.  So it's simple to keep tabs on items such as free disk space, free memory, programs that are using up all your CPU time, and so on.
Unlike programs such as BGinfo, which I've mentioned before, Rainmeter constantly updates its information rather than just imprinting it onto your desktop wallpaper at startup.  So the data is always up to date.
You'll find Rainmeter at and it's a download of around 2.3 MB .  The program is malware-free according to VirusTotal and Web of Trust.

Don't think one can really blame Microsoft - Firefox warns that the site certificate is invalid which is a fairly common problem as people self-certify of let their certificates expire. Easy to then just tell FF to ignore the problem if you wish to....

A red herring, MrDog! You're mixing two separate problems.

First, the app installation certificate problem --- markd gives the best solution/workaround.

Second, browser access to

Firefox 43.0.4 gives error-free access (no certificate warning) is NOT self-certified --- it was issued by COMODO ECC Domain Validation Secure Server CA 2 --- valid from Thu, 29 Oct 2015 00:00:00 UTC --- valid until Sun, 24 Apr 2016 23:59:59 UTC

This site works only in browsers with SNI support --- a good security point --- so some OLDER browsers may be problematic

All this may be checked at:-
SSL Server Test: (Powered by Qualys SSL Labs)

along with the site's excellent "A" security rating.

One last point, this Gizmo article fails to mention that "Rainmeter is open source software distributed free of charge under the terms of the GNU GPL v2 license." --- Open Source wins every time!

Spot on! The 'certificates' warning message has nothing to do with Microsoft, it's down to the browser. Make sure your date and time are set correctly. If that's all good, then do as MrDog says and just tell Firefox to ignore the problem - provided you are sure the download is coming from a known safe and reputable source, of course.

For those people having trouble installing this on WIndows 10. Click on 'More Info' in the top left corner of the window that says Rainmeter cannot be installed - and you will see an option 'Run Anyway'. All done :)

I couldn't find I just get ERR_SSL_VERSION_OR_CIPHER_MISMATCH (Chrome)
However, Firefox worked fine.

The reason Win 10 will not allow the download is the same as the reason it is deleting programs.
Certificates not issued by Microsoft will flag as harmful.
As a freelance programmer it should be a crime for Microsoft to steal programs created by others.
To get a certificate to use your program, they want the rights to the code used to create the program.
Any freeware program thus become a Microsoft Partner Product and can be bundled in their sold products.
We use to call this high piracy to steal technology, like the government still does.

Just downloaded onto Win7 with no trouble...neat. If continue to have no problems will change to 5*. Thanx.

WIN10 says the "Signature for Rainmeter 3.3 is corrupt or invalid" and I couldn't download.
