Does anyone have any advice to make my Acer Aspire One usable on windows 10

I get no errors, it is just very slow (it was never quick) but it is unusable slow these days.

I remembered I did have problems with an intermittent BLACK SCREEN where the mouse and keyboard did not work no "control alt del" etc.

actually the laptop reminded me.....

I could see disk activity, so not crashed, I found that putting the laptop to sleep with the power button, and reawakening and logging in "cured" it temporarily . I checked at the time for a graphics driver upgrade, but it appears Intel are no longer supporting the HD500 chipset.

I have allowed the laptop to upgrade itself to windows 10 1909 plus cumulative updates..... during the 1903 phase the BLACK SCREEN  above occurred several times. once upgraded to 1909 the screen "flashed" BLACK for several seconds  every time the screen was updated.

To upgrade the HD500 graphics driver I tried to use the Intel driver support utility but it would not let me run it without logging into intel, and did not format correctly on the browser to do so.....

So I resorted to DEVICE MANAGER that had failed to allow an upgrade of the HD500 driver before, strangely it allowed me to search for a driver and offered an Intel HD500 driver and a Microsoft generic driver, it successfully loaded the HD500 driver (with same driver date ???) and it now seems fairly stable. (watch this space).

While the above was going on I researched upgrading the hardware, It has 2gb memory and can't take more, the hard drive could be upgraded to SSD, the only problem I can see is that task manager shows it is CPU bound without to much disk activity. This points a future upgrade to SSD.

I have followed this sites advice to speed up the laptop by removing the windows fancy features.

How to disable visual effects on Windows 10

In order to manage visual effects to speed up Windows 10 use the following steps:

Use the Windows key + R keyboard shortcut to open the Run command.

Type sysdm.cpl and click OK to launch System Properties.

Under "Performance," click the Settings button.

on the resulting "performance" screen I deselected everything except  "smooth edges of screen fonts"...

WOW THAT MADE A BIG DIFFRENCE

Now the system is upgraded I remove many of the MS APPS ( news health groove etc) 

It is 90% of what I wanted. I will keep looking, and see if it remains stable graphics wise.

Doing a fresh Win10 installation usually solves such problems. You must first back up all your data and collect all application installation files & product keys.

Thank you Frederik, I shall not do this for now, although it may be the quickest route to a cure....
