COmputer slow

My computer has become slow though I have more than 450 GB free space in C drive. My laptop has 1 TB hard drive alloted space in total.

With a Win10 PC, you're almost always going to experience a very slow PC for a while because Windows Update (WU) is hogging your PC, searching for, downloading, and installing updates -- to bring your PC up to the most current version of Windows.

To find out what version and build of Win10 your PC is running, do the following:\1) enter "cmd" (without the quotes) into the search area and select the Command Prompt option
2) enter "winver" into the command window (again, without the quotes)
3) the most current Win10 is v1809 Build 17763.253

If yours is older than that, most likely WU is hogging your PC trying to update it.

To disable WU temporarily, do the following:
1) Enter "services" in the search area (again, without the quotes)
2) When the window opens, scroll down until you see Windows Update
3) If it say Running under status, that indicates that WU is running
4) To change that, double-click on that task, select Stop under the Service status, and then Apply
5) That should stop WU -- and you should see an immediate improvement in performance

WU will restart itself automatically later on, so you basically have no choice thathan to bear with it until it finishes.
