Downlooad and Install Dll Files: How to Resolve - ALT & TAB function hanging up?

ALT & TAB function hanging up

Hi - When I try navigating between windows using the ALT & TAB function the display window that pops up showing the open windows sometimes freezes and cannot be closed or clicked on.
I have to do the CTRL ALT DEL (Windows Task Manager) to close all windows
then sometimes a small window pops up asking if I want to close the program. If this window does pop up and I choose the Close the Program option the window that is frozen will clear. Most of the times I have to reboot. This has only started after I upgraded
from Vista to 7 with the free upgrade CD. Hopefully someone else has had this problem and found the solution that they wish to share. THANKS

Don't Download Malware

Where are you getting the download?

There are malicious people who download valid copies of a popular download, modify the file with malicious software, and then upload the file with the same name. Make sure you are downloading from the developer's web page or a reputable company.

Don't install download manager

Many sites suggest or require you to install an installer or a download manager before allowing you to download a program you may be interested in downloading. These tools almost always cause your computer more problems and may even have malware or other spyware. Avoid any site claiming anything must be installed first before you can continue with your download.

Avoid advertisements on download pages

To help make money and pay for the bandwidth costs of supplying free the software, the final download page may have ads. Watch out for anything that looks like advertisements on the download page. Many advertisers try to trick viewers into clicking an ad with phrases like "Download Now", "Start Download", or "Continue" and that ad may open a separate download.

Cancel or deny any automatic download

Some sites may automatically try start a download or give the appearance that something needs to be installed or updated before the site or video can be seen. Never accept or install anything from any site unless you know what is downloading.
