Your first screenshot shows that you are attempting to open a file with an extension of
crdownload
That file extension is usually associated with Google's Chrome browser. It is a temporary file extension given to a file during the download. Once the download completes, there are a few more things that might occur before the original file extension is assigned to the file.
One of those things is:
Security related Chrome extensions (apps) might need to complete their checking of the file.
Another thing is:
Antivirus apps (in this case, Kaspersky) might might need to scan the file.
I downloaded Kaspersky 14.0.0.4651 from here:
Download Kaspersky Anti-Virus 14.0.0.4651 - FileHippo.com
(234MB)
During install, it downloaded another 168MB of stuff.
After the install, it downloaded lots more files.
Wow!
I downloaded Chrome 31.0.1650.63 from here:
Download Google Chrome 31.0.1650.63 - FileHippo.com
After restarting the Virtual Machine that I'm playing in, I used Chrome to download the System Update Readiness Tool (SURT) from here:
Download System Update Readiness Tool for Windows 7 for x64-based Systems (KB947821) [November 2013] from Official Microsoft Download Center
Using Process Monitor, I did not see Kaspersky do anything with the file during or after the download. Perhaps I just missed Kaspersky's actions.
My temp file correctly renamed from
Windows6.1-KB947821-v31-x64.crdownload to
Windows6.1-KB947821-v31-x64.msu after the download completed.
I used the default settings for Kaspersky - maybe your settings/results are different.
I would suggest that you try downloading the SURT using another browser. The final download size looks correct in your first screenshot, but I would not attempt to manually rename the file.
In your second screenshot, I noticed that...
"
Some settings are managed by your system administrator".
That is typically something that you might see if the computer is a member of a domain. You system specs say that your computer is running
OS win 7 64 Home edition - which (as far as I know) cannot join a domain. Are the screenshots in your post from your W7 Home system? Or are we talking about a work computer?
I've seen antivirus products (security suites) also take over Windows update settings, but they usually replace "
your system administrator" with the software product name.
If this is your work computer, forum members should not help you get around your system admin's setup.
