Windows 7 ultimate x64 reaches blank welcome screen on boot,no desktop

Hey guys there is a problem with my computer acer aspire desktop pc
It happened directly after running ccleaner registry fixer, at which point nothing would load as if the file associations in the registry became corrupt. Microsoft word was bringing up an install wizard and things suchas msconfig.exe and cmd.exe could not be found. When i restarted the computer a blank welcome screen appeared and the "welcome" text has changed to some form of windings, that disappears leaving a welcome screen background and a mouse pointer, the screen flashes on and off every 10 seconds.

I do have an acer recovery disk but it doesnt work for some reason, i have also tried system resotre but there were no restore points, icannot access the desktop of the computer so i had to use startuo recovery

Startup recovery found an error and asked my to reboot, but the same events occured. It then found nothing atall after that. I then booted from a usb a system recovery tool that found nothing wrong but allowed me to view the computer and now i can access all of the partitions and have copied over important + relevant folders via usb. But as i saidm i can now access everything on the hardrive, is there anything i can delte and redownlod and copy over?

This is the screen i am greeted with.

This really sounds like intentional damage to annoy the user. Why?
- Deleted file associations
- Weird behaviour
- Deleted or replaced system fonts
- Deleted cmd
- Deleted all system restore points (or have you disabled system restore in the first place?)

You tried:
- Acer recovery disc
- Startup recovery

Your options:
- Wait for other members to suggest less destructive ideas on how to fix this
- Try to revert all this damage somehow manually, which will be difficult and might be impossible

I would suggest:
- Now that you can access your drive, back up everything you want to keep on an external hard drive or USB stick.
- Perform a clean install

Everything possible is here for Troubleshooting Windows 7 Failure to Start
leading up to if necessary rescuiing your files to do a perfect Clean Reinstall Windows 7.

I doubt if CCleaner was responsible as we've never seen such a case. More likely there was infection or corruption problems. If you can get into Safe Mode or as soon as it will start again I'd run the Malwarebytes scan provided.
