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

It seems Windows does not like the RAMDrive when performing large updates, I never heard of that before, but it would be best not to use that when updating your system.

Answer 2

I lost an edit. It tried with temp folder on same partition as Windows 10, then on another drive, both worked.

Answer 3

This is strange, if the RAMDisk is causing the updates to fail, then you will need to disable that and use a Temp folder on another drive, are you short of space on your System Drive?

Answer 4

Apparently it uses the temp directory for the download. If I set ramdisk to 1GB, small updates worked, but large updates failed during download. I switched to using a temp folder on the same partition and also on another drive, both worked. My system has 32GB of ram, so I could use a larger ramdisk, but was concerned about 2 step updates.

Hi, I am Dave, I will help you with this.

The installation files for Windows updates are not stored in the normal Temp folder, they are stored in a new temporary folder created for the update directly in the root of the C drive, so using a RamDisk should not cause any problems.
