    I am running windows 10 on my HP Notebook PC. Sinch March, i have been having problems with my computer lagging for a long time as the disk usage shoots up to 100% whenever i try to connect it to the internet or whenever i plug in my charger or my phone to the laptop. After about an 50/60 minutes, the disk usage comes down to normal and it starts working normally. Another thing is that my laptop takes a long time (about 20 minutes) to boot and come to the password screen.
    I have done a defrag of my device, disabled superfetch, updated windows defender, ... Basically everything. I have checked my drives they all are indicated as healthy.
    Everytime the disk is at 100 the svchost.exe windows image acquisition or local network service pops defender is not able to detect any viruses either. Is this a. Hardware or a software problem? Do you have any suggestions besides clean formatting the windows?

    I tried the first two options to no avail but struck gold when I disabled Flash. Disk usage instantly dropped from 100% to 8. Thank you so much!

    I tried all four methods to no avail. There must be another possibility. But i learnt something doing this, so thank you for that. For those who found the commands worked for them, it may be useful to put those commands in a .bat file for easy execution at a future date, if needed.

    Hi Christian,

    I cannot thank you enough. I spent many hours of time trying fix this problem. Geek Squad had control for 4 hours, found and wiped out viruses (good), but still couldn't fix it.

    It was Adobe flash - which I disabled using your instructions. (it had cause problems in the past, but I thought I had 'fixed' them).

    I have a major work deadline so you have truly made a difference.

    Thank you again!

    I'm a fair bit older, we got a TRS80 when I was about 19 , I don't miss it as it wasn't very good really. I got more into the zx80, even though you had to waggle the ram pack when it crashed (often), I had more fun with the ZX Spectrum that was great.I got the tape streamer the lot. The The first paid program I ever wrote was on Windows 3.1 and 3.11, around 92/93, about the same time I first installed Linux.when. After learned C and c++ (one of, if not The first, object oriented programming course in the country at that time I believe. We did real time Ada too. Since then it's been OO and GUI all the way, with web development this last 15 years or so, that was a bit like starting again with the early tools/languages. I can only say it's lot easier and more entertaining with current technology/languages, much as I enjoyed tinkering with the early ones. It's weird to realise that I started at the virtual beginning, although I missed the first PC's in 80's, they didn't catch my imagination really, although I did some dBase III on one back, but that was just tedious :) A bit sobering to look back on, we have come a long way in not that long a time - from my perspective anyway :)!

    Had the usual array of UK "home computers" before that starting with the ZX81.

    My first was the DIVINE Commodore 64! How many of us started out in computing using that baby? Best keyboard ever, best data storage (okay, the Datasette wasn't going to win any prizes for speed, but it was RELIABLE.....none of that fiddling about with the volume control to make it work!)

    I wrote my first ever program on that thing; a 'Hangman' program, with a database of all of 20 words....

    A mate of mine used the TRS-80; the 'Trash 80', as it was popularly known, due to its ability to suddenly lose every bit of your work, without you having anything to do with it...!!

    I bought one of the 1541 floppy drives. Horrible things; had a habit of melting the insides, due to excessive heat production from the drive motor and controller. But compared to the Datasette, oooh.....they ran like lightning. Happy days!

    It's unbelievable what folk are STILL doing with them. Hard drives, optical drives, huge amounts of RAM (GB instead of KB!).....look for yourselves, the hobbyists are showing Jack Tramiel what SHOULD have been done originally (except that the technology didn't exist in those days)...

    Our first computer was a Sinclair ZX81 it had 1K memory. After that was the 16K ZX Spectrum which we also got the keyboard and later upgraded to 48K. Incredible what those computers could do with those specs.

    My first, a $80 Timex/Sinclair 1000 with 2k RAM (got the $150 16k upgrade module that plugged in the back) and a membrane keyboard...40 columns of black and white text on a 13" TV lol. Nothing like typing on a keyboard you couldn't feel at all :)

    Second, the amazing Commodore 64, 40 columns of COLOR on a 13" TV! Had the 1541 5.25" floppy drive, perched on 4 No. 2 pencils stuck in the screw recesses in the bottom because of known cooling problems har!
    An interesting cartridge program I had for that system was the GEOS operating system. Like Damian above, it put Windows 1.0 to shame.
    A girlfriend of mine had a Commodore +4 at that same time, and two or three friends of mine had the VIC-20's.

    Third, the Commodore 128 in all its NCC 1701D-like flashiness, with a revolutionary 80 columns on a 13" TV with the 1571 floppy drive...
    It had a secret weapon built in, the Zilog Z80 CPU, which allowed it to run CP/M (anyone ever heard of that little operation?), in addition to Commodore BASIC. It was literally two computers in one case.

    Fourth, a Fastdata 386/40 IBM clone (yeah, that was the THING back then...IBM clone...same cachet as a jailbroken iPhone lol), 30mb hard drive. That was a Windows 3.1 machine.

    Ha Mike Myers, my buddy with his PC Jr. was jealous too...though I did like his Microsoft Flight Simulator with its mega wow vector line graphics...
    He had a Texas Instruments TI-99 too that I never did warm up to.

      You guys are all making me want to buy a vintage Commodore. I learned how to "code" in BASIC on that and an IBM PC 486.

    I'll tell you a story and you might even believe it... in 1985 Atari produced an amazing 32bit computer (TT) with a hybrid GUI based on Xerox revolutionary development GUI and though it had little software and a few games, it was massively advanced when compared to "Windows". I could sum up this little story by simply saying "Microsoft set the entire Computing industry back 10 years right from the beginning and has since reduced evolution to a crawl so that now, the industry must be 20 or more years behind where it actually should be". It's true and sad. You know what's even sadder is that Windows 10 "Windows Explorer" has loosely the same look and feel at Atari's TT GUI did in 1985 - and Windows 10 is not as nice looking! What a sham... Having said this, I do enjoy my Windows 7-64 Ultimate Power User system with 3 displays, really big sound & lots of power every day, in spite of knowing how pathetically far behind it truly is... It's also true that as result Apple & Linux are also behind but at least they are refined. Mint Linux 17.2 KDE and Apple OS 10.11 as examples...

        Hi Bryan,

        Atari had quite a successful line of computers, although not on the level of Commodore or Apple. The Atari 400 was a PC that looked vaguely like an Apple II and had a single cartridge port on top. The Atari 800 was an expansion on the 400's power, and had dual cartridge slots (the carts were labelled left slot, right slot). The Atari 800XL, and 130xe competed with the Commodore 128, and had better graphics for games akin to an Atari 7800.

        Lots of Atari's. :)

          That's really cool. I just did some searching to see what these looked like. Quite cool.

          Sidenote: I see that some of these are going for a small fortune now.

    The good 'old' Radio Shack TRS-80 Model III. I had a whopping 16k RAM and since I couldn't afford the 5 1/4 floppy for it (the PC itself ran me $990) I had to make due with their cassette tape for storing my program projects. No Windows - just DOS. My first PC upgrade was to up that baby from 16k to a whopping 48k RAM. At the time I seem to recall that upgrade costing me a little less than $100 itself.

    My first work PC was the original IBM PC/XT with 640KB of RAM and a 10MB hard drive. It had a Hayes 1200 bps modem and the DOS 2.0 that would allow me to make directories arrived a week after I got the machine.

    No-name XT clone. 1MB RAM, 32MB hard drive, 4-color CGA graphics. Originally had no mouse or modem; within a couple of weeks I had added both. It originally ran DOS 3.3; later I upgraded to DOS 6.22, then DESQview. That was the computer I used for about three or four years.

        Check out DOSBox. It's an amazing self-contained DOS environment, and you can install and run any old DOS games in it with sound card emulation, and proper CPU speed for the old games. There's also a Windows 3.1 environment version of DOSBox and it's great for playing old Windows games.

      Funny to think that 30Mb was once considered a ton of storage… but it’s true. I can’t even imagine how you would use that much storage back then. You sir, had a beast of a machine.
