All Major Windows Services Broken! URGENT - Please Help!

Okay I have no idea where to start. Yesterday my friend needed me to test something for him in MySQL, a program I had installed a while back. When I tried to get in, it told me that I needed a root password. Since I forgot that, and I had no idea how to log in, I used Revo Uninstaller Pro to uninstall MySQL and delete all the leftover files and registry values that it left behind. I'm not sure if that is what caused it or something else that I can't remember, but since last night a lot of my computer services aren't working.

Edit 4:

SOLVED

I can't install/uninstall any programs.

I can't access/turn on System Restore and clicking on 'Turn System Restore on or off' does nothing.

I can't access System Information

I can't access System Properties

In addition, I can't click the properties of any folder (If I try to right click My Computer and hit properties, nothing happens), my computers sound is not working, my taskbar shows my internet as offline even though its working and I can't open pictures
I also cannot run SFC / Scannow

or Run Windows Update

I also feel like there might be something wrong with my graphics diver, because as I've been typing this post, my screen keeps flashing to my desktop.

Edit 1: My video driver was in fact affected by it, as I can't watch any videos, and attempting to crashes my firefox plugin process.

I cannot pull up my specs using the program 'Speccy' because it says Class Not Registered for everything. I've also lost the CD for my Windows 7 Ultimate, so I don't know if I could use that to fix it.


UNSOLVED


I can't log into MySQL.

I have my Control Panel listed as a menu in my Start list, but when I highlight it, it shows the Control Panel as empty.

I can't turn on my Windows Security Center

Any help would be greatly appreciated.

This is viral behavior , really nasty one from the looks of it, the best thing I can tell you is boot safe mode with networking download malwarebytes free version, install it , let it update and do a full scan.
Malwarebytes : Malwarebytes Anti-Malware is a free download that removes viruses and malware from your computer

Afterwards you're going to need to run this
SFC /SCANNOW Command - System File Checker

and you may possibly need to reassociate the exe file type.
That can be found here.
Default File Type Associations - Restore

I would do the steps in that order.

well skip to my sfc step. It will at least check the integrity of the core windows files.
SFC /SCANNOW Command - System File Checker

If you can't get it to run from in windows you may need to use the repair console off your disk.
you are running it from the command window and not in the run box right?

You have some serious issue here then.
This method may work
SFC /SCANNOW : Run in Command Prompt at Boot

Edit 3: Okay here's the update after I reverted those registry changes (through Revo Uninstaller Pro):

Sound is WORKING

Video is WORKING

Pictures are WORKING

My Computer Properties window is WORKING

Internet is now showing ONLINE

Windows Firewall is WORKING

Windows Update is WORKING

System Information is WORKING

System Properties is WORKING

Control Panel Menu is still NOT WORKING

Windows Security Center is still NOT WORKING

System Restore is still DISABLED

Things still left to check: Installer, SFC /SCANNOW, MySQL
