Windows 7: What are the risks of "killing" my CMOS?

If your motherboard doesn't have the CMOS clear jumper then with the machine powered down you can remove the battery for a few minutes which will accomplish the same thing. There is no danger in clearing the CMOS but, as already pointed out, it's possible to brick your machine trying to flash your BIOS.
I'm too afraid to reset it "physically" since I'll probably mess something up, somehow. This is probably why someone made a bootable program for it :P Those settings sound easy enough, I was afraid I'd have to re-enter complicated stuff. First I'll look at what my boot order is and see if it is indeed loading other things before the hard drive.

I think I made a little connection here. Maybe resetting the CMOS doesn't do anything to fix a long boot time, except making you need to redo your boot order, so it loads the hard drive first again. I'm sure it's a possibility.

I did a boot with Soluto and it said it took 5:23 to boot my system. I did the math for all the listed programs and unfortunately it's right. Something just seems a bit fishy. Why would it take over 4 minutes to boot up all the "necessary" Windows stuff? The longest application to boot is the operating system itself with 36 seconds. It is 4 minutes due to the sheer number of "Windows" stuff that piles on at boot. My security and drivers only take a measly 43 seconds.

Edit: My hard drive does boot first so we can rule that out.

As mentioned you shouldn't need a utility to do it. It's easy to do with the jumper on a desktop, not so easy on a laptop. Removing the cmos battery on a laptop is even tougher. The easy way is to boot the PC and hit the required key to enter the BIOS settings. Then look for a "reset to factory defaults menu option". I haven't seen a BIOS without that option in there some where. I think if you read up on that kill cmos utility you will find its more geared towards erasing the BIOS password. I would advise caustion on using it. On a desktop reseting the BIOS with the jumper erases the BIOS password and your back in. On a laptop it doesn't, the BIOS info is stored differntly and it isn't erased by removing the BIOS battery. It's done that way on purpose so someone can't easily bypass the boot password on a stolen laptop. The BIOS info is stored in an EEPROM and has to be electronically erased.

The CMOS is just where your BIOS (program) stores it's settings. The only time the normal user need touch the hardware is to change the battery every 10 years or so.
Of course you can enter the BIOS setup at boot time. But before you select "Set to default" I would go through all the BIOS settings and write down what they are currently set to for your PC (that's your default).

I'm not even so sure if my problem lies in the CMOS now according to Soluto. I reset the settings back to default in my BIOS and it didn't make any difference. This is quite troubling. According to Soluto, my boot is 5:23 with much of the time eaten up by everything needed by Windows. Over 4 mins is dedicated to 37 apps that are said to be necessary for Windows to function, and the 2 others are my antivirus and Soluto itself. My "optional" programs only take 41 seconds. Actually, I think I'm going to take a look at Windows features and clean out what I never plan on using.

Have you used msconfig to view/control what programs are being loaded at Startup? (Click on the Start orb, type "run" (no quotes) in the Search box, then click on "Run" in the list. When the Run window opens type "msconfig" (no quotes) and press Enter. Once the msconfig opens, go to the Startup tab). There you will be able to view what programs are being loaded at Startup and you can disable unnecessary ones by removing the check in the checkbox. Lots of apps install "helper" programs that run at startup that do things like check for updates and such, they aren't really necessary and slow your boot time as well as chew up valuable RAM.

Yup, I've disabled the unnecessary stuff at start-up.

Enable a boot log in msconfig>boot to see what driver might be hanging during bootup.

What registry cleaner are you using? Be aware that almost all Registry Cleaners besides the industry's state-of-the-art genius app CCleaner are sales operation scams. I would System Restore to before you installed any other Reg Cleaner, or if necessary run a Repair Install to reinstall the registry.

Open a CMD line to run as Admin sfc /scannow to check for system file damage.

Google any repeat errors in Event Viewer>Admin View to find how others have resolved them. Check also the Performance log which logs app/driver hangs, located on Advanced Tools page accessed by clicking WEI score link at Computer/Properties. Look for cued issues on Tools page, then Generate A System Health Report.

The only tweaking Win7 needs is cleaning and ordering the HD perfectly using CCleaner and Auslogics Disk and Registry defraggers monthly.

You really shouldn't need to 'kill' or reset your cmos unless it is to clear out a set password on your motherboard or you changed CMOS settings so horribly wrong that you can't get access to the machine at all.

Most computers have built in 'defaults' you can fall back on within the CMOS itself, and the only time it can get corrupt is when people monkey around with the settings or, as someone else pointed out, flashed the bios incorrectly, but at that point, the computer is a brick unless the board has recovery methods you can use.

The solution for a failed BIOS flash is to flash the BIOS, preferably from Windows.

Won't work if the BIOS is corrupt though, as you can't boot into windows or even get into the BIOS setup routine. The BIOS has to be working in order for you to flash it. You only out is if you are lucky to have boot block or a dual bios with a recovery option.
