"Patch Tuesday" and Temp/Tmp folders on a RAM disk

I'm using the "Set Windows TEMP folder..." feature of SoftPerfect RAM Disk to redirect Temp and Tmp variables from the %USERPROFILE%\AppData\Local\Temp folder to a 1GB RAM disk whose content is erased on every boot.

Can this kind of setup cause problems with Windows 10 periodic updates that probably use the above-mentioned temporary files folder to apply the fixes of each "Patch Tuesday"?

Thank you.

As far as I know Windows updates use the system temporary folder, which is usually C:\Windows\Temp, instead of the user temporary folder in %USERPROFILE%\AppData\Local\Temp

At least, we have never had any problems with updates with user temporary folders TEMP and TMP pointing to a volatile RAM disk.
