Norsemen,
Try resetting your phone. If it does not help, then flashing using the WDRT program.

[yorik5555]

Norsemen,
if the body was not new, it is still desirable to completely clean everything up and go through a long way.

Yorik5555 @ 03/18/17, 10:00 PM

rollback to 8 via WDRT - XP without recovery - installation 10 - XP without recovery (when starting the installation, manually disable all offers from t-shirts about reports and collaboration) - update to the last build - then everything else.

[mmvaglo]

Good player updated. Used on 8.1 Now there is also for WM10https: //www.microsoft ...tore/apps/9wzdncrdc1k6

[art555ua]

Recently, the keyboard has often become slowed down, when typing in characters, tell me the solution, please

[mmvaglo]

art555ua
Try to restart the device, the RAM may be clogged. Add paging file.
Here is the soft for a quick reboot. It is placed after Interop Unlock through the device portal.

Reason for editing: Added file

[art555ua]

The paging file 512 1024 is worth it, there were a couple of applications in the memory, but as it was unloaded they felt better, apparently this is the case

[Sobakolub]

For the third day, the People tile is not working.

[vlad7917]

SobakolubMaybe the connection with the account has fallen off?

[Sobakolub]

Vlad7917 @ 03.28.17, 09:39

Sobakolub, can the connection with the account fall off?

No, everything is fine, all contacts are clinging and adequately displayed, but the live tile just died and everything. And it rebooted, and deleted the tile, and deleted the register, and re-hooked, but to no avail.

Earned after deleting temporary files.

SobakolubI suggest that as an experiment next time, if something like this happens, just do nothing. And, something tells me that without your "reboots", "unhooked-hitch" everything will work. 3-4 day wait. : yes2:

Yes, through the browser, click add - deploy

[mmvaglo]

der_meister1974,
Perhaps not made Unlock. I have established without problems.

[der_meister1974]

mmvaglo,
Interop Tools is installed, but apart from the registry editor, I did not change anything else in it. Maybe tell me what you need to include there to put this application?

[Dr_Capacitor]

Is there any application or can the automatic switching on of the hot spot when the device is connected via Bluetooth can be configured in any way?

[mmvaglo]

der_meister1974,
There is no need to change anything. Unlock simply allows the installation of third-party applications. Try without a device portal, drop the application on the SD card and install via explorer.

[yorik5555]

der_meister1974 @ 03/30/17, 10:07

I just threw the unzipped file into the SD root and clicked on it through the explorer in the phone - everything fell off half a ping.
have long wanted to have such a button

[Roman290]

Guys tell me, I correctly understood to install the program from the memory card, do I need to make an interlop unlock? And they could not throw a link to the instruction with the easiest way, how much I looked, read, I did not fully understand
