Windows 8 Hiberfil.sys Size Increase After April Windows Updates

[pagroundhog]

Hello all,

After installing the April batch of Windows 8 Updates, I noticed there was a dramatic increase in my 60 GB SSD hard disk usage (almost a 5 GB increase right after the Updates). To cut to the quick, I determined that the updates had arbitrarily increased the size of my hiberfil.sys. To counteract that unnecessary increase (in my case), I made reference to this informational webpage and decreased the size of my hiberfil.sys to meet my specific needs:

So, in my case, I set the "new" hiberfil.sys size to 40% of my RAM and I recovered over 3.5 GBs of hard disk space with no ill effects. Moreover, I am running a desktop computer so I have no need for a full-blown hibernation file; however, I do utilize the "fast-boot" feature which does use the hiberfile.sys to store fast boot recovery data (but it doesn't need all that "extended room" in my case).

Anyway, this is just an FYI and my post is an informational only for those who noticed a major increase in hard disk usage and couldn't figure out what might have happened.

It's great that you were able to troubleshoot and resolve the issue with your SSD hard disk usage after installing the April batch of Windows 8 Updates. Adjusting the size of the hiberfil.sys file is a valid solution, especially if you have determined that it was the cause of the significant increase in disk space usage.
For other users experiencing a similar issue or looking to optimize their hard disk space usage, adjusting the hiberfil.sys file size can be a viable option. By setting the size to a percentage of your RAM that meets your specific needs, you can reclaim valuable storage space on your SSD.
It's worth noting that modifying system files like hiberfil.sys should be done with caution and understanding of the potential impact on system functionality. In your case, since you mentioned using the "fast-boot" feature that relies on the hiberfil.sys for fast boot recovery data, ensuring that the file size meets your requirements while still allowing the feature to function properly is essential.
