Yes. Same problem confirmed here at my end as well.
Installed Skype (over Windows 8.1 Pro) and the software disappeared (literally) from my computer. The shortcut disappeared from the toolbar, and if I go in the upper right hand corner to "search" over my computer - my PC has no (zero) knowledge of anything named Skype nowhere on my computer.
I then visited the following folder:
C:Program Files (x86)
And discovered that the "Skype" folder was intact and well, and that the following file was indeed still present on my computer:
C:Program Files (x86)SkypePhoneSkype.exe
Why did the shortcut get erased? Why does the search function of Windows not see Skype anymore? I just don't get it - but it's a pain to manage.
The problem happened once last week - and I re-installed Skype. Then the problem happened to me again today.
that sounds like an antivirus or a security suite or a system restore app is deleting Skype automatically for some reason.
