Windows Updated Now Low Hashrate-Ethereum

[fuzion1]

Hello,

I have 3 rigs that did a windows update today even though I have it disabled..    Before the update I was getting 27mhs with CLaymore Ethereum.  Now I am getting 18mhs.  I rolled back the update.  I did a DDU, and then reinstalled the AMD Blockchain driver.  I am still getting 18mhs.. Can anyone tell me how to fix this?

You forgot to switch each card to Compute from Graphics after the driver install...

What the GPUs series?

What the version your Claymore?

Restart CLaymore and wait...

if still dropped...restart Window

Yes I had this happen also.

Was very annoying and had no idea the window update will also update the AMD drivers.

I noticed when I got the code 43 for no reason .

Since you don't want Windows updating your drivers, I would disable drivers updates in Windows Update.

gpedit ==> Computer Configuration ==> Administrative Templates ==> Windows Components ==> Windows Update and set 'Do not include drivers with Windows Update' to enabled.

I was curious what happend with difficulty today, it was huge drop for all coins. Now that explains. If u disable updates normal ways, then they will come, becasue windows defender will restore your changes to allow updates.
