Disk usage getting 100%

[Ganesan023]

When starting the laptop, the disk usage getting 100% and laptop work too slow, it takes more than an hour get back to normal state. Once it's come to normal, the laptop will be working fine. But again we restarting the laptop, the same issue again occurs and takes time more than an hour to get back to normal state.

One possibility is that Windows Update is running on your PC and that is know to be a processor and disk usage hog.

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.
