When I log in, Windows will show desktop quickly, but on the desktop I can not interact with anything, because it will simply do nothing, for example I can right click taskbar and click Task Manager, but it will open only after it unfreezes, which usually takes about 15-30 seconds. While it's frozen most of the icons are blank and after unfreezing they load and also auto-start programs finally begin to load.
I am using AVG 2014, but I don't think that could be the problem, because it was installed for a long time without any problems.
Fast (hybrid) boot is disabled.
What have I tried already?
sfc /scannowand it didn't find any integrity problems.
How can I fix this or find out what is causing this freeze? Thanks for any answers.
NORMAL: This is normal behavior. When you start your machine the most basic information is processed first, like showing the desktop, turning on the graphics, locating the mouse and keyboard drivers, etc. But depending on what you have installed on your computer, virus programs installed, they all get started and some of your programs like Chrome or Desktop shortcuts may have not been initialized during the booting process. Just because you logged in and see your Desktop doesn't necessarily mean that the programs and everything in it is ready to go. It's like getting into a very cold car turning the key and hitting the gas, it might and might not work sometimes a warming up process is necessary.
In my case, this has been caused by TeamViewer. By disabling the "TeamViewer 14" service, in the System Configuration (msconfig.exe), the problem has been solved.
