Windows 7: copy and paste not work at all!!!

copy and paste not work, been like that for 1 or 2 weeks now, anyone help me! I been looking on google but anything nothing help...

Two things to try. First, change to a basic theme and reboot to see if this is caused by Aero. If that doesn't work, try booting to safe mode and see if you can C&P in safe more. If so, you have some program or service that is interfering with C&P. If it works in safe mode, you can try a clean boot to see if you can determine what is causing it.

I did went to safe mode, still have problem same as before... can you give me regedit where re-enable copy and paste also i noticed that when I copy words or files to other place or on website... just won't work at all so, can you help me?

This is not an easy issue to fix, I know of no reg edit to make it work, as we don't know why it stopped working.

I'd suggest you try the System File Checker

SFC /SCANNOW Command - System File Checker

If no fix, my next choice would be a system restore point before the problem started (if you have one)

System Restore

If not, then you may need to do a Repair Install
