Windows will prompt you to free up disk space or use external storage to temporarily extend the storage on your PC. This will result in a longer offline install time.įor PCs that don't have enough space to automatically install the update Windows will automatically optimize for reducing the amount of free disk space required to install the update. Learn more about our efforts to reduce offline time during updates (English only at this time).įor PCs with limited free space but still enough to complete the update automatically Windows automatically tries to complete more of the update process in the background while you use your PC. This significantly reduces the time your PC will be offline (or unusable) during the update, although it might temporarily use more disk space to complete the update.

Windows follows three different feature update paths, depending on the amount of disk space currently available. For more info, see How reserved storage works in Windows.

Also, my backup program had not run in over a week so it was past time to start it again.Note: For devices with reserved storage, an update will first use the reserved storage space before using other disk space. I had already wasted too much time on this so it was time to move on. The files would then no longer be fragmented. I ended up deleting all the backups and creating new backups.īTW, I may have tried copying the files to another drive and copying them back. Even deleting the older backups so the drive was down to 20% used did not seem to help. De-fragmenting seem to stall even after several days at 20%. What made it worse was that several of the backup files were over 1TB in size. I noticed there was a problem when my backup program estimated it would take over 24 hours to back up my 2 x 2TB internal SSDs. Would the data automatically be copied back in a defragmented way?I had the same problem with my 12TB external hard drive. Will it be quicker if I move the data off to another drive, then copy it back. Running a defrag is taking days with no end in site. I have a 14tb HDD that's 90% full and windows says 80% defragmented.
