Will using ramdisk for temp folder cause a problem with Windows 10 update?

Question

When doing a Windows 10 update to Windows 10 version 22H2, it gets to 30% of the update, then a reboot is done to complete the update. Dose this require that the temp files be saved until the update completes, in which case a ramdisk temp folder would be an issue since it gets reset on each reboot.?

Answer 1

There is an apparent informational or understanding conflict regarding Windows Updates and their storage location. What I mean by this is that like others I employ a RamDisk for Temp files. However, there are certain occurrences where WUpdate will fail to complete an update that requires a reboot. Temporarily resetting the Temp locations to non-RamDisk storage location permits the WUpdate to complete successfully.

The conflict that I see is that "Temp" is not equal to "%SYSTEMROOT%\SoftwareDistribution". Resetting WUpdate clears out this directory where WUpdates are stored. Given that, why is a Temp located in RamDisk a factor in 'some' Wupdates?

Answer 2

I've avoided doing large updates with ramdisk. I could probably set it to 1GB, so a large update would fail on download, but for now I'm just using a folder on the Windows 10 partition.
