Windows 10: Download and install all button greyed out

I need to install an urgent security update on my computer, but all I'm getting is this, any help would be much appreciated.

:)

 

Download button in ovistore is not active (grey)

This seems to be the case for me too but not on all downloads, it appears to be that for apps previously downloaded & still installed the button is greyed out, often though even if the app was uninstalled the button is still greyed out moreso with paid for
apps but for free ones the button is active/green.

 

The download button is grey for Facebook for E71/72

Hi I deleted my facebook app on my E72 by accident. I went to ovi store on my E72 tried to reinstall it, and the download button is grey. I went to my stuff section, still the same. I deleted my download history from ovi store website, and entered mobile
ovi store again, still the same . Any suggestions? Cheers

 

greyed out Print button in file explorer with .htm Extension windows 10

Hello,

There are options you can consider to troubleshoot this issue. When the
Print button on the File Explorer window is greyed out, we suggest that you check if the
Print Spooler service is running. To do this, simply follow the steps below:

• On the Cortana search box, type Services and click the
  Services app.
• Scroll down and check if the Print Spooler service is running.
• If not, right-click Print Spooler and click Properties.
• On the Properties window, click Start.

After following the steps, check if the Print button
is already available.

Should you have further questions, feel free to post them on this thread.
