Don't use this if you don't like exe starting with your system, taking resources, etc. also it might be unsafe. I found this a while ago somewhere via google, but it said to put this into autostart, sadly it doesn't work with autostart if you don't sign out after you login and the login again (and sometimes it doesn't work at all).
After you apply your desired font size in windows settings (like 125% dpi, I use this with 125%) > Open notepad, paste this into it:
then save it as <yourname>.cmd somewhere on your HDD > open local ground policy editor (gpedit.msc from search bar) > In user config (im translating this from my language so there might be little translation differences) > go to Windows Settings > Scripts (login/logout) > In the window on the right double click on Login to open it (because we want this to be applied every time you login) > in Scripts tab, select Add > then in new window select Browser > navigate to where you saved your cmd file and select it > then just press Ok > Apply > Ok > Then sign out/reboot your pc > Login to your account for the first time after adding this script so it will be applied > then if it will not work, Sign out/reboot again and from now on it should work every time (works for me).
REG ADD "HKCU\Control Panel\Desktop" /v DpiScalingVer /t REG_DWORD /d 0x00001018 /f
REG ADD "HKCU\Control Panel\Desktop" /v Win8DpiScaling /t REG_DWORD /d 0x00000001 /f
REG ADD "HKCU\Control Panel\Desktop" /v LogPixels /t REG_DWORD /d 0x00000078 /f
I noticed that fonts are much more crystal clear everywhere now, it seems MS messed up badly with dpi in windows 10... In some places font is only 5~10% blurry (right mouse click menu, display settings etc.) while in others (device manager for example) is 100% blurry. After this I have crystal clear fonts everywhere :3
This is not a driver issue... it's issue with how dpi is made, Windows 8.1 has this issue as well to some degree if you don't use the old dpi scaling but apply dpi scaling separately to your monitors, then for example lauch steam after that, it will be all zoomed in and blurry as hell. I don't even know where did it came to you about driver, especially that if you google a lot of people having blurry fonts on dpi higher than 100% and are looking for fix.
Another BS... 100% is default, if we would be comfortable with size of the font to our eyes at 100% we wouldn't be changing DPI wouldn't we? 100% is too small to read.
I wouldn't as well, I don't like this method, so i searched, finally found this script above somewhere, I'm sad there is so little options, mostly this software comes up everywhere :/ I found this script on forum in a single post in a thread with a lot of replies... that's why I decided to post it here since it's the 1st thing that comes up with google -_-
