The scaling depends on your setting for Logpixels You have 78 which is 125%.
To get the scaling you require multiply 96 by your percentage and then convert to hex so for 250% it is 96*250/100 = 240. Convert this to hex is F0 so you would want to put in the value
Here are some other scaling factors just in case.
REG ADD "HKCU\Control Panel\Desktop" /v LogPixels /t REG_DWORD /d 0x000000F0 /f
Note that on latest release 10856 the blurry text has gone (for me at least) so this fix isn't required any more.
DpiScalingVer - originally 1000
Win8DpiScaling - originally 0
LogPixels - originally absent
144(x90)--->150% ** Current**
Every 25% of the scale factor corresponds to a difference of 24 dpi (120-96)
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 0x00000090n /f
