My windows 10 laptop in showing always 100% disk usage,

[pritam2904]

My laptop is Pavilion X360 u 104TU, I bought it in 2017, for 1 year, it was good,, but for last 1 yr I'm having issue is that the disk usage is showing 100%. I have done all the things that I can get from google. Today even I have done the recovery also, but after that also its showing 100% disk usage. There is no extra software loaded in my laptop. Now i dont know what to do. I'm thinking of swapping my hdd with a ssd. Will it work? Or what should I do?

You claim to be running Win10, and in that case, Windows Update could easily be the culprit -- and if so, that is solveable...

With a Win10 PC, you're going to experience a variety of problems not typical of the older PCs.

First is sluggishness. You may experience a very slow PC at times 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. This can also contribute significantly to high processor temperatures, as it is being heavily used.

Second is fan noise. That's directly related to fan speed, which is the result of processor heat, and WU is known to drive up the processor load -- sometimes to 100%. That can cause the fan to run loud and continuous for some time.

Third is disk usage. WU can easily force the disk usage to 100% and and keep it pinned there for some time. That's because it writes WU files to the drive, then it turns around and reads them, then it overwrites existing Windows System files. All of that takes a lot of disk usage to complete.

These processes are compounded by Win10 because new Win 10 patches coming out nearly every Tuesday. Since you can't stop Updates like you did with Win7, this means you're going to get updates, regardless of what you do.

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 versions as of 7/9/19 are the following:

a) v1803: Bld 17134.915

b) v1809: Bld 17763.615

c) v1903: Bld 18632.239.

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

Some folks have been told that resetting your PC will fix this. but, if you reset your PC, you only make matters WORSE! Why? Because you will reset Win10 back to the original version that came preloaded on the PC and that will restart Windows Update all over again.

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.

If not, then WU is not the problem.

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