Ive been having problems with my audio jack so samsung support suggested i done a reinstall from inside windows, it found and started downloading the 25h2 repair version but so far its been installing for HOURS!
In around 7hrs its now at 57%, i have checked in task manager and my 0 drive is mostly at 1% and hardly being used but ram is using around 11gb.
It is installing, but VERY slow, is there anything i can do to speed it up? its now nearly 9pm and dont want to be up all night with this.
Thanks

If it will be hard for you to interpret results, please share them to OneDrive, I'll look into them.

Do you have enough free space on the drive?

Unfortunately, there is nothing to do while install is running.

2026-08-30T20:33:30.17+00:00 This may depend on Windows itself problem that can be removed by reinstallation mainly or on hardware problem.
Please check hard drive with third-party CrystalDiskInfo tool and show its window.
How long ago did you defragment your hard drive?

2026-08-30T22:38:15.5533333+00:00 Hi, its a samsung galaxy book4 edge laptop and i bought it brand new in april, the hardrive has hardly been used really as havent downloaded much at all, have a few apps and a couple of songs, also a few pics stored but thats it.
It is a snapdragon x plus ARM processor though which isnt the best for windows.
