Since earlier this week, my laptop becomes unresponsive when logging into windows. Disk C: is always at 100%. Windows will only be usable and lag free after around 15 mins. Open Resource Monitor shows me that these are usually the causes: pagefile.sys, softwaredistribution/datastore, app/data/local/comms/unistoredb/store

Also, my shutdown and boot times are prolonged. Booting would take 20 mins or more. The screen would get stuck at the manufacturer logo and the loading of windows.

I have already disabled windows apps from running in the background, disabled superfetch and windows search.

I have run full anti-virus scans and chkdsk scans, but they don't report any problems.

Logging onto different windows accounts doesn't solve it. I also removed my windows account and emails (mail and calendar apps)

All my drivers are up-to-date as well.

The last solution i haven't tried is doing a reset but as much as possible, i don't want to lose my installed programs

My machine: i5 processor, 4gb RAM, 1TB hard drive (Drive C: 209/372 GB, Drive D: 156/537)

  • By C: disk is always at 100%, do you mean the processor %? Or, the actual space left seen from My Computer is at 0? If this is processor usage, you need to isolate the application causing this. You've mentioned pagefile.sys, if so, try changing how much memory is paged: windows.microsoft.com/en-us/windows/… – Dandy Feb 5 '16 at 6:08

    Also check you hard drive for errors. I had a drive that would act like this and it eventually currupted. – NetworkKingPin Feb 5 '16 at 7:49
  • @AaronLayfield by 100% I mean the active time/disk transfer rate, not the storage in My Computer. I have changed the paging memory values. Initial: 200 MB, Maximum size : 1393 MB but to no effect. I have identified the processes/services causing this which is coming from the Unistore folder but have no idea how to stop these at startup – sigs Feb 7 '16 at 1:40
  • @NetworkKingPin I checked for errors but none showed. Both in chksdsk and analyze for defrag – sigs Feb 7 '16 at 1:42
