Hello, i am having a problem with windows 7. I just recently upgraded from windows vista ultimate to windows 7 home premium. Every time i start my computer i can't click or right click the taskbar or any open window. I have to hit ctrl-alt-delete to open the task manager and thats the only thing that gets it working again. I don't have any viruses or spyware, ive done /sfc scannnow and checked the hard disk for errors and it still happens. Does anyone have a solution??? i seriously don't know what to do now.

I'm sure someone has heard of this before? Please help

Hi Deep_chunk, I agree with Kris that this issue can be related to third party software or services. You can try the following suggestions and see if the issue can be resolved: 1. Download ShellExView v1.41 from the following link http://www.nirsoft.net/utils/shexview.zip Please Note: The third-party product discussed here is manufactured by a company that is independent of Microsoft. We make no warranty, implied or otherwise, regarding this product's performance or reliability. 2. Right-click the "shexview.zip" file, select "Extract All", the Extraction Wizard will prompt. 3. Click Next, input "C:\ShellExView" (without the quotation marks) in the "Files will be extracted to this directory" textbox. 4. Click Next and click Finnish. 5. Open the "C:\ShellExView" folder and double-click the "shexview.exe" file. It will scan the registry for all the shell extensions. 6. Select all the non-Microsoft extensions in pink by press "Ctrl" in the keyboard. 7. Click the "Disable Selected Items" on the toolbar and click Yes. 8. Restart your computer and check if the issue is resolved. Also, access Clean Boot to check the issue. If the issue disappears in the Clean Boot environment, you can continue to narrow down which entry is causing the issue. If the issue still exists, create a new user account and see if the issue occurs. Regards, Linda I also am experiencing this issue. I have followed all of the suggestions above and none have resolved the issue. Can anyone suggest anything else I can try, please? Thanks John

Iam experiencing the same issue. The system was freshly installed. For me it does not happen every single time so it is pretty hard to "debug" this issue by turning off services or other things. Is there anybody who found the cause of this issue so far?

I have the same problem and it is not related to 3rd party apps. This started happening maybe a month ago where randomly you can't click the task bar or title bar. The only workaround is to ctrl+alt+del and then cancel (it seems to take a 2nd click before cancel responds). I say it isn't related to 3rd party apps because I've just done a clean install of Windows 7 Pro 64 bit and just installed the WIndows update and the same problem happens

same exact problem here. This is a dell latitude e5400. user reported they couldn't click on anything. first thought was the touchpad was going bad. not the case. i have already reimaged this latop with the same image that is on this same model all over this site, and no other machines have this problem. control+alt+delete then cancel brings back all functionaltiy. im putting in an order to have the hard drive/motherboard replaced and then i'll reimage it again.

Just tested the mouse thing and when I think back I wasted my wireless mouse with liquids ... Still worked, but the issue started then. New mouse / Old mouse, just not the broken mouse ...

I had the exact same problem and it turned out to be my wireless Logitech mouse. As soon as I plugged in the receiver and turned it on, some programs were fine but no mouseover or clicks registered on the taskbar, including clicks with my touchpad. I have to reboot Windows 7 with the mouse detacted to regain use of the taskbar. It was pretty easy for me to guess it was the mouse since I'd just dropped it on a tile floor 10 minutes before...

Well, I had a similar problem but mine would only stop working if i opened a browser (specifically Chrome). The moment i would close this, it would continue to function as normal. I ran a clean startup and yet chrome hung the taskbar. I wasnt even able to use IE9 as it had a similar effect on the taskbar. So i got rid of chrome and now everything is back to normal. I am now posting this reply via IE9 with no problems at all... Hope this works for you guys too. P.S. I know how frustrating it gets. Cheers
