Hello everyone I have first 250 gb HDD where Windows 8.1 is located and second 500 gb where is disks D: and E: After installing Update 1 through the MS windows update I noticed that some programs start working slower than before update. For example: I have Rosetta Stone installed on disk D (second 500gb disk), before update 1 it worked normal but now it stuck freeze during data reading from disk D: By the way the size of data is 1-2 MB, but during reading it looks like disk is overload Don't know what to do, is there any way to roll back?
