Pc running slow after windows 10 upgrade.

Hi , Can someone please help, since i upgrades from 8.1 to 10 my pc runs really slow.
My pc was running on 8.1 32 bit with no problems.
Can anyone please help.

Do you mean the PC is slow to boot or is slow when booted? If slow when booted, the first step would be to look at running tasks using Task Manger to identify processes having a high CPU / memory / disk load and troubleshoot accordingly.

If the PC is slow to boot, you could consider the following:

1. Try Autoruns and disable any start-up programs you don't need?
2. Run SFC/SCANNOW to check for system problems?
3. Are there any mapped network drives or mapped drives which may slow logon?
