Apache xampp does not start

Question

I have the old problem with xampp and Apache and Apache not starting. This is a windows 10 machine running xampp-win32-5.6.31-0-VC11. I also tried 7.1.9-0-VC14 with the same problems. The problem is:

12:47:45 AM  [Apache]   Error: Apache shutdown unexpectedly.
12:47:45 AM  [Apache]   This may be due to a blocked port, missing dependencies, 
12:47:45 AM  [Apache]   improper privileges, a crash, or a shutdown by another method.
12:47:45 AM  [Apache]   Press the Logs button to view error logs and check
12:47:45 AM  [Apache]   the Windows Event Viewer for more clues
12:47:45 AM  [Apache]   If you need more help, copy and post this
12:47:45 AM  [Apache]   entire log window on the forums

Log files on xampp are empty. I changed the ports 80 to 8080 and 443 to 4433 in the config files (found on the internet). I checked the netstat tool (both on xampp and on powershell). netstat on xampp did not show anything on port 80, 8080, 443, or 4433. netstat -aon on powershell gives a long output with the only "80"thing here:

TCP    192.168.88.125:49203   185.22.69.180:80       TIME_WAIT       0
TCP    192.168.88.125:65508   185.22.69.180:80       TIME_WAIT       0

and the only "443" thing here:

TCP    10.145.128.214:64112   10.144.187.242:443     TIME_WAIT       0
TCP    192.168.88.125:49320   40.77.229.18:443       ESTABLISHED     6728
TCP    192.168.88.125:49694   40.77.229.47:443       ESTABLISHED     6728
TCP    192.168.88.125:63719   2.20.161.124:443       CLOSE_WAIT      10168
TCP    192.168.88.125:64019   151.101.65.69:443      ESTABLISHED     2080

So, no occurrence of 8080 or 4433 on either netstat on xampps or netstat on powershell.

Any ideas what might be going wrong? By the way: I do not have admin privileges. But I know people with the same kind of privileges that are able to run xampp. I am able to run installers with something very close to admin rights - I can find out exactly what these rights are. I did run xampp installer using these privileges.

I can't add comment so asking in answer section.

Do you have skype or any proxy running on system?
